平时我们编写WinForm程序经常使用VS进行拖控件的方式，这样做虽然简单，但是无法深入了解WinForm程序的本质。其实，用记事本也可以编写出VS编写的WinForm程序。还是直接看代码吧：

1、打开记事本，写入以下代码，另存为hello.cs文件


using System;
using System.Windows.Forms;
namespace Hello
{
 public class Form1:Form
 {
  private System.Windows.Forms.Button btnClose;
  public Form1()
  {
    this.Text = "Form1窗体";
    btnClose = new System.Windows.Forms.Button();
    //将窗体挂起
    this.SuspendLayout();
    //设置按钮属性
    this.btnClose.Location = new System.Drawing.Point(20,20);
    this.btnClose.Size = new System.Drawing.Size(100,25);
    this.btnClose.Name = "btnClose";
    this.btnClose.Text = "按钮";
    this.btnClose.UseVisualStyleBackColor = true;
    //设置按钮控件点击事件
    this.btnClose.Click += new System.EventHandler(this.btnClose_Click);
    //将构造的控件添加到窗体Controls控件集合
    this.Controls.Add(btnClose);
  }
  //按钮点击事件
   private void btnClose_Click(object sender,EventArgs e)
   {
   this.Close();
   }
 }
 public class Program
 {
  //程序入口
  public static void Main()
  {
   Application.Run(new Form1());
  }
 }
}
