这几天闲着没有事，想编写一个模仿QQ显示与隐藏的程序，现在有问题如下：

{

private int x,y;
private System.ComponentModel.IContainer components;
public Form1()
{
//

//

//
}
/// <summary>

protected override void Dispose( bool disposing )
{
if( disposing )
{
if (components != null)
{
components.Dispose();
}
}
base.Dispose( disposing );
}

this.SuspendLayout();
//

this.label1.Location = new System.Drawing.Point(40, 144);
this.label1.Name = "label1";
this.label1.TabIndex = 0;
this.label1.Text = "label1";
//

//
this.AutoScaleBaseSize = new System.Drawing.Size(6, 14);
this.ClientSize = new System.Drawing.Size(172, 471);

this.Move += new System.EventHandler(this.Form1_Move);

上面红色部分代码为什么运行不到啊？
