仿照窗体应用程序编写：
任务一：生成一个Form类的窗体对象frm
using System.Windows.Forms; //using指令使用Form对象创建所需的命名空间
//如果using指令不成功，则应该去添加引用，如图
using System.Drawing;
namespace WindowsFormsApplication6
{
public partial class Form1 : Form //Form是空白窗体
{
//Form1继承于空白窗体，又通过构造函数添加新的控件button等
public Form1() //构造函数
{
InitializeComponent(); //初始化函数
}
private void InitializeComponent() //初始化函数
{
this.textBox1 = new System.Windows.Forms.TextBox(); //创建新的textbox1控件
this.SuspendLayout(); //挂起控件更新，使得以后一同更新
//
// textBox1
//
this.textBox1.Location = new System.Drawing.Point(108, 128); //属性设置
this.textBox1.Size = new System.Drawing.Size(100, 21);
this.textBox1.TabIndex = 0;
//
this.textBox1.Name = "textBox1";
// Form1
//
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.ClientSize = new System.Drawing.Size(284, 261);
this.Controls.Add(this.textBox1); //添加新生成的控件textbox1
this.Name = "Form1";
this.Text = "Form1";
this.Load += new System.EventHandler(this.Form1_Load);
this.ResumeLayout(false);
this.PerformLayout();
}
}
