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());  } }}
