使用文本编辑器创建简单的 C WinForms 应用程序

  1. 打开文本编辑器(如记事本),然后键入以下代码:

     using System;
     using System.ComponentModel;
     using System.Drawing;
     using System.Windows.Forms;
        
     namespace SampleApp
     {
         public class MainForm : Form
         {
             private Button btnHello;
        
             // The form's constructor: this initializes the form and its controls.
             public MainForm()
             {
                 // Set the form's caption, which will appear in the title bar.
                 this.Text = "MainForm";
        
                 // Create a button control and set its properties.
                 btnHello = new Button();
                 btnHello.Location = new Point(89, 12);
                 btnHello.Name = "btnHello";
                 btnHello.Size = new Size(105, 30);
                 btnHello.Text = "Say Hello";
        
                 // Wire up an event handler to the button's "Click" event
                 // (see the code in the btnHello_Click function below).
                 btnHello.Click += new EventHandler(btnHello_Click);
        
                 // Add the button to the form's control collection,
                 // so that it will appear on the form.
                 this.Controls.Add(btnHello);
             }
        
             // When the button is clicked, display a message.
             private void btnHello_Click(object sender, EventArgs e)
             {
                 MessageBox.Show("Hello, World!");
             }
        
             // This is the main entry point for the application.
             // All C# applications have one and only one of these methods.
             [STAThread]
             static void Main()
             {
                 Application.EnableVisualStyles();
                 Application.Run(new MainForm());
             }
         }
     }
    
  2. 将文件保存到你具有读/写访问权限的路径。在包含它的类之后命名文件是常规的 -​​ 例如,X:\MainForm.cs

  3. 从命令行运行 C#编译器,将路径作为参数传递给代码文件:

     %WINDIR%\Microsoft.NET\Framework64\v4.0.30319\csc.exe /target:winexe "X:\MainForm.cs"
    

    注意: 要将 C#编译器的一个版本用于其他 .NET 框架版本,请查看路径%WINDIR%\Microsoft.NET 并相应地修改上面的示例。有关编译 C#应用程序的更多信息,请参阅编译并运行第一个 C#程序

  4. 编译完成后,将在与代码文件相同的目录中创建名为 MainForm.exe 的应用程序。你可以从命令行运行此应用程序,也可以在资源管理器中双击它。
