C# Description详细阐述

一、cba赛程

C#是微软公司推出的一种针对Windows平台的高级编程语言。而C#对于很多开发者来说，就像NBA对于球迷一样，是一种热爱和追求。在C#的社区中，类似NBA赛程一样的热门话题，就是cba赛程。这里我们将以使用C#实现获取最新cba赛程为例，详细阐述C#的WEB服务。

首先我们需要创建一个ASP.NET WEB服务项目，然后在代码中使用HttpClient进行cba网站的数据请求，获取json格式的数据后进行反序列化，最终获取最新的cba赛程。以下是相关代码实现：

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
{
    /// 
    /// 获取cba赛程的WEB服务
    /// 
    [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#开发一个教练管理系统，可以让我们更好地了解C#的面向对象思想和语法知识。下面是一个简单的代码实例展示如何创建一个Coach类：

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节目表

C#可以用来开发跨平台的移动应用程序。在移动应用的开发中，往往需要使用到网络请求和数据解析，以下是在C#移动应用中获取cctv5节目表的相关代码：

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的部分代码
    }

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

四、chat GPT人工智能

使用C#开发聊天机器人的应用程序是一个不错的练手项目，下面我们展示的是如何把GPT人工智能集成到C#聊天机器人中：

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()
    {
        // 省略获取token的部分代码
    }
}

C#可以用于开发桌面应用程序，比如视频播放器。以下是一个简单的代码实现展示如何使用C#实现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("请先安装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驾照能开什么车

使用C#实现一个C1驾照考试题库，可以更好地了解C#操作数据库的知识。以下是相关代码实现：

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反应蛋白高说明什么

在健康检查中，如果我们的c反应蛋白高了，就说明可能存在炎症、感染等相关问题。使用C#可以开发健康管理应用程序，将c反应蛋白高值输入进去，给出相应的健康分析报告。以下是相关代码展示：

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", "无");
        }
        else if (crpValue <= 3.0)
        {
            return new HealthAnalysisReport("中等", "中等", "感染风险、炎症风险");
        }
        else
        {
            return new HealthAnalysisReport("健康风险", "高", "感染、肿瘤等慢性发病风险");
        }
    }
}

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;
    }
}
