lblName.Text = "姓名:";
TextBox txtName = new TextBox();
Button btnSubmit = new Button();
btnSubmit.Text = "提交";
btnSubmit.Click += (sender, e) =>
{
MessageBox.Show("您好," + txtName.Text + "!");
};
lblName.Left = 20;
lblName.Top = 20;
txtName.Left = lblName.Right + 10;
txtName.Top = lblName.Top;
btnSubmit.Left = txtName.Left;
btnSubmit.Top = txtName.Bottom + 10;
form.Controls.Add(lblName);
form.Controls.Add(txtName);
form.Controls.Add(btnSubmit);
Application.Run(form);
}
}
3、掌握WinForms的布局方式,包括绝对布局、流式布局、表格布局等。
using System;
using System.Windows.Forms;
class Program
{
static void Main(string[] args)
{
Form form = new Form();
FlowLayoutPanel panel = new FlowLayoutPanel();
Button btn1 = new Button();
btn1.Text = "1";
Button btn2 = new Button();
btn2.Text = "2";
Button btn3 = new Button();
btn3.Text = "3";
panel.Controls.Add(btn1);
panel.Controls.Add(btn2);
panel.Controls.Add(btn3);
form.Controls.Add(panel);
Application.Run(form);
}
}
三、ASP.NET MVC开发
1、了解MVC框架的基本原理及使用方法,掌握Controller、Model、View三者的关系及其作用。
using System.Web.Mvc;
class HomeController : Controller
{
public ActionResult Index()
{
return View();
}
}
2、熟悉ASP.NET MVC的路由配置、数据传递、表单提交及验证方法。
using System.Web.Mvc;
class HomeController : Controller
{
public ActionResult Index()
{
ViewBag.Message = "Hello World!";
return View();
}
[HttpPost]
public ActionResult Submit(string name)
{
ViewBag.Message = "Hello, " + name + "!";
return View("Index");
}
}
3、掌握ASP.NET MVC的常用扩展功能,包括身份认证、授权、缓存等。
using System.Web.Mvc;
class HomeController : Controller
{
[Authorize]
public ActionResult Secret()
{
ViewBag.Message = "Secret page!";
return View();
}
}
四、异步编程
1、了解异步编程的优势及必要性,掌握async和await关键字的使用方法,提高代码的性能。
using System.Threading.Tasks;
class Program
{
static async Task Main(string[] args)
{
Console.WriteLine("开始执行");
await Task.Run(() =>
{
Console.WriteLine("耗时操作");
});
Console.WriteLine("执行完毕");
}
}
2、学习使用Parallel类进行并行计算,提高程序的效率。
using System.Threading.Tasks;
class Program
{
static void Main(string[] args)
{
Parallel.For(0, 10, i =>
{
Console.WriteLine("执行并行操作:" + i);
});
}
}
3、熟悉使用Task.Delay方法实现定时器功能,掌握异步编程中时间操作的方法和技巧。
using System.Threading.Tasks;
class Program
{
static async Task Main(string[] args)
{
Console.WriteLine("开始执行");
await Task.Delay(5000);
Console.WriteLine("5秒钟后执行");
}
}
五、数据访问
1、了解ADO.NET的基本概念及使用方法,包括连接、命令、数据读取器等。
using System.Data.SqlClient;
class Program
{
static void Main(string[] args)
{
string connectionString = "Data Source=myServerAddress;Initial Catalog=myDataBase;User ID=myUsername;Password=myPassword";
using (SqlConnection connection = new SqlConnection(connectionString))
{
connection.Open();
using (SqlCommand command = new SqlCommand("SELECT * FROM Students", connection))
{
SqlDataReader reader = command.ExecuteReader();
while (reader.Read())
{
Console.WriteLine(reader["Name"].ToString());
}
}
}
}
}
2、掌握使用Entity Framework框架进行ORM映射,提高编程效率。
using System.Linq;
class MyContext : DbContext
{
public DbSet Students { get; set; }
}
class Student
{
public int Id { get; set; }
public string Name { get; set; }
public int Age { get; set; }
}
class Program
{
static void Main(string[] args)
{
MyContext context = new MyContext();
List students = context.Students.Where(s => s.Age > 18).ToList();
foreach (Student student in students)
{
Console.WriteLine(student.Name);
}
}
}
3、了解Redis数据库的基本概念及使用方法,掌握C#中对Redis的访问方法。
