C# Description詳細闡述

一、cba賽程

C#是微軟公司推出的一種針對Windows平台的高級編程語言。而C#對於很多開發者來說，就像NBA對於球迷一樣，是一種熱愛和追求。在C#的社區中，類似NBA賽程一樣的熱門話題，就是cba賽程。這裡我們將以使用C#實現獲取最新cba賽程為例，詳細闡述C#的WEB服務。

首先我們需要創建一個ASP.NET WEB服務項目，然後在代碼中使用HttpClient進行cba網站的數據請求，獲取json格式的數據後進行反序列化，最終獲取最新的cba賽程。以下是相關代碼實現：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net.Http;
using System.Web;
using System.Web.Services;
using Newtonsoft.Json;

namespace CBAWebService
{
    /// 
    /// 獲取cba賽程的WEB服務
    /// 
    [WebService(Namespace = "http://cba.com/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    public class CBASchedule : WebService
    {
        [WebMethod]
        public string GetSchedule()
        {
            using (var httpClient = new HttpClient())
            {
                var result = httpClient.GetAsync("http://cba.sports.sina.com.cn/cba/schedule/index.json").Result;
                var json = result.Content.ReadAsStringAsync().Result;
                var schedule = JsonConvert.DeserializeObject<List<Schedule>>('[' + json + ']');
                var latestSchedule = schedule.OrderByDescending(s => s.date).ThenByDescending(s => s.id).First();
                return JsonConvert.SerializeObject(latestSchedule, Formatting.None);
            }
        }
    }

    public class Schedule
    {
        public string date { get; set; }
        public string time { get; set; }
        public string leftTeam { get; set; }
        public string rightTeam { get; set; }
        public string url { get; set; }
        public int id { get; set; }
    }
}

二、coach

使用C#開發一個教練管理系統，可以讓我們更好地了解C#的面向對象思想和語法知識。下面是一個簡單的代碼實例展示如何創建一個Coach類：

public class Coach
{
    private string name;
    private int age;
    private string teamName;

    public Coach(string name, int age, string teamName)
    {
        this.name = name;
        this.age = age;
        this.teamName = teamName;
    }

    public string GetName()
    {
        return this.name;
    }

    public void SetName(string name)
    {
        this.name = name;
    }

    public int GetAge()
    {
        return this.age;
    }

    public void SetAge(int age)
    {
        this.age = age;
    }

    public string GetTeamName()
    {
        return this.teamName;
    }

    public void SetTeamName(string teamName)
    {
        this.teamName = teamName;
    }
}

三、cctv5節目表

C#可以用來開發跨平台的移動應用程序。在移動應用的開發中，往往需要使用到網路請求和數據解析，以下是在C#移動應用中獲取cctv5節目表的相關代碼：

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        GetCctv5ProgramTable();
    }

    private async void GetCctv5ProgramTable()
    {
        var client = new HttpClient();
        var response = await client.GetAsync("http://api.cntv.cn/epg/getEpgInfoByChannelNew?c=china&d=20210822&p=1&v=4&cb=epgnew&_=" + GetTimeStamp().ToString());
        var result = await response.Content.ReadAsStringAsync();

        // 省略解析json，更新UI的部分代碼
    }

    private int GetTimeStamp()
    {
        return Convert.ToInt32(DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1)).TotalSeconds);
    }
}

四、chat GPT人工智慧

使用C#開發聊天機器人的應用程序是一個不錯的練手項目，下面我們展示的是如何把GPT人工智慧集成到C#聊天機器人中：

public class Gpt2Bot
{
    private DefaultHttpClient httpClient = new DefaultHttpClient();

    public async Task<string> GetResponse(string query)
    {
        var json = JsonConvert.SerializeObject(new { textInput = query });

        var httpRequestMessage = new HttpRequestMessage
        {
            Method = HttpMethod.Post,
            RequestUri = new Uri("https://api.ai21.com/gpt2?max_tokens=64&temperature=0.7"),
            Headers =
            {
                { HttpRequestHeader.ContentType.ToString(), "application/json; charset=utf-8" },
                { "Authorization", "Bearer " + GetAuthToken() }
            },
            Content = new StringContent(json, Encoding.UTF8, "application/json")
        };

        var httpResponseMessage = await httpClient.SendAsync(httpRequestMessage).ConfigureAwait(false);
        httpResponseMessage.EnsureSuccessStatusCode();

        var responseBody = await httpResponseMessage.Content.ReadAsStringAsync().ConfigureAwait(false);
        var responseJson = JsonConvert.DeserializeObject(responseBody);
        return ExtractTextFromJson(responseJson);
    }

    private string ExtractTextFromJson(dynamic responseJson)
    {
        // 省略解析json
    }

    private string GetAuthToken()
    {
        // 省略獲取token的部分代碼
    }
}

五、cctv5在線直播

C#可以用於開發桌面應用程序，比如視頻播放器。以下是一個簡單的代碼實現展示如何使用C#實現cctv5直播：

public partial class MainForm : Form
{
    private HttpServer _localServer;
    private Process _vlcPlayerProcess;

    public MainForm()
    {
        InitializeComponent();
    }

    private void MainForm_Load(object sender, EventArgs e)
    {
        var m3u8Url = "http://lives.cctv.com/1001.m3u8";

        var vlcPlayerPath = @"C:\Program Files (x86)\VideoLAN\VLC\vlc.exe";
        if (!File.Exists(vlcPlayerPath))
        {
            MessageBox.Show("請先安裝VLC播放器");
            return;
        }

        try
        {
            _localServer = new HttpServer(m3u8Url);
            var localUrl = "http://localhost:" + _localServer.Port.ToString() + "/";
            _vlcPlayerProcess = Process.Start(vlcPlayerPath, localUrl);
        }
        catch (Exception ex)
        {
            MessageBox.Show(ex.Message);
        }
    }

    private void MainForm_FormClosing(object sender, FormClosingEventArgs e)
    {
        _localServer?.Dispose();
        _vlcPlayerProcess?.Kill();
    }
}

public class HttpServer : IDisposable
{
    private readonly HttpListener _listener;
    private readonly string _url;
    private readonly byte[] _buffer = new byte[0x10000];
    private Task _acceptTask;

    public int Port { get; }

    public HttpServer(string url)
    {
        _url = url;
        _listener = new HttpListener();
        _listener.Prefixes.Add(url);
        _listener.Start();

        Port = new Uri(url).Port;

        _acceptTask = Task.Factory.StartNew(AcceptConnections, this, TaskCreationOptions.LongRunning);
    }

    private async Task AcceptConnections()
    {
        while (_listener.IsListening)
        {
            try
            {
                var context = await _listener.GetContextAsync();
                var buffering = context.Response.SendChunked;
                var requestUrl = context.Request.RawUrl;

                using (var client = new HttpClient())
                {
                    var response = await client.GetAsync(requestUrl);
                    var content = await response.Content.ReadAsByteArrayAsync();

                    context.Response.ContentLength64 = content.Length;
                    await context.Response.OutputStream.WriteAsync(content, 0, content.Length);
                }
            }
            catch (HttpListenerException) { }
            catch (ObjectDisposedException) { }
        }
    }

    public void Dispose()
    {
        _listener?.Stop();
        _listener?.Close();
        _acceptTask?.Dispose();
    }
}

六、c1駕照能開什麼車

使用C#實現一個C1駕照考試題庫，可以更好地了解C#操作資料庫的知識。以下是相關代碼實現：

public class Question
{
    private readonly string _connectionString;
    private readonly MySqlConnection _conn;

    public int Id { get; set; }
    public string Title { get; set; }
    public string OptionA { get; set; }
    public string OptionB { get; set; }
    public string OptionC { get; set; }
    public string OptionD { get; set; }
    public string Answer { get; set; }
    public string Analysis { get; set; }
    public int Type { get; set; }

    public Question()
    {
        _connectionString = ConfigurationManager.ConnectionStrings["QuestionDB"].ConnectionString;
        _conn = new MySqlConnection(_connectionString);
    }

    public void Insert()
    {
        _conn.Open();
        var insertCommand = new MySqlCommand
        {
            Connection = _conn,
            CommandText = "INSERT INTO question (title, option_a, option_b, option_c, option_d, answer, analysis, type) " +
                "VALUES (@title, @optionA, @optionB, @optionC, @optionD, @answer, @analysis, @type);"
        };
        insertCommand.Parameters.AddWithValue("@title", Title);
        insertCommand.Parameters.AddWithValue("@optionA", OptionA);
        insertCommand.Parameters.AddWithValue("@optionB", OptionB);
        insertCommand.Parameters.AddWithValue("@optionC", OptionC);
        insertCommand.Parameters.AddWithValue("@optionD", OptionD);
        insertCommand.Parameters.AddWithValue("@answer", Answer);
        insertCommand.Parameters.AddWithValue("@analysis", Analysis);
        insertCommand.Parameters.AddWithValue("@type", Type);

        insertCommand.ExecuteNonQuery();
        _conn.Close();
    }

    public Question GetById(int id)
    {
        _conn.Open();
        var selectCommand = new MySqlCommand { Connection = _conn, CommandText = "SELECT * FROM question WHERE id = @id" };
        selectCommand.Parameters.AddWithValue("@id", id);

        var reader = selectCommand.ExecuteReader();
        var question = new Question();

        while (reader.Read())
        {
            question.Id = reader.GetInt32("id");
            question.Title = reader.GetString("title");
            question.OptionA = reader.GetString("option_a");
            question.OptionB = reader.GetString("option_b");
            question.OptionC = reader.GetString("option_c");
            question.OptionD = reader.GetString("option_d");
            question.Answer = reader.GetString("answer");
            question.Analysis = reader.GetString("analysis");
            question.Type = reader.GetInt32("type");
        }

        reader.Close();
        _conn.Close();

        return question;
    }
}

七、c反應蛋白高說明什麼

在健康檢查中，如果我們的c反應蛋白高了，就說明可能存在炎症、感染等相關問題。使用C#可以開發健康管理應用程序，將c反應蛋白高值輸入進去，給出相應的健康分析報告。以下是相關代碼展示：

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void btnAnalysis_Click(object sender, EventArgs e)
    {
        var crpValue = Convert.ToDouble(tbxCRPValue.Text);
        var healthReport = GetHealthAnalysisReport(crpValue);

        lblOverallHealth.Text = healthReport.OverallHealth;
        lblInflammationRisk.Text = healthReport.InflammationRisk;
        lblPossibleDiseases.Text = healthReport.PossibleDiseases;
    }

    private HealthAnalysisReport GetHealthAnalysisReport(double crpValue)
    {
        if (crpValue < 1.0)
        {
            return new HealthAnalysisReport("健康", "低", "無");
        }
        else if (crpValue <= 3.0)
        {
            return new HealthAnalysisReport("中等", "中等", "感染風險、炎症風險");
        }
        else
        {
            return new HealthAnalysisReport("健康風險", "高", "感染、腫瘤等慢性發病風險");
        }
    }
}

public class HealthAnalysisReport
{
    public string OverallHealth { get; }
    public string InflammationRisk { get; }
    public string PossibleDiseases { get; }

    public HealthAnalysisReport(string overallHealth, string inflammationRisk, string possibleDiseases)
    {
        OverallHealth = overallHealth;
        InflammationRisk = inflammationRisk;
        PossibleDiseases = possibleDiseases;
    }
}
