纯手工打造C#窗体程序,CSC编译后只有6KB
程序如下：
加控件

//窗体

			this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;

			this.Name = "MainForm";

			this.AutoScaleBaseSize =new System.Drawing.Size(216,14);

			this.ClientSize=new System.Drawing.Size(380,280);

			this.Text="纯手工打造C#窗体程序";

			this.ResumeLayout(false);

			

			//文本框

			this.textBox1=new System.Windows.Forms.TextBox();

			this.SuspendLayout();

			this.textBox1.Location=new System.Drawing.Point(24,48);

			this.textBox1.Name="textBox1";

			this.textBox1.Size=new System.Drawing.Size(224,21);

			this.textBox1.TabIndex=0;

			this.textBox1.Text="按住鼠标右键在窗体上移动！ ";

			this.Controls.Add(this.textBox1);

			//label1

			this.label1=new System.Windows.Forms.Label();

			this.label1.Location=new System.Drawing.Point(24,24);

			this.label1.Name="label1";

			this.label1.Size=new System.Drawing.Size(168,16);

			this.label1.TabIndex=1;

			this.label1.Text="鼠标的当前应用程序屏幕坐标";

			this.Controls.Add(this.label1);

定义鼠标响应事件

//定义三个鼠标事件处理程序的委托关联			

		    this.MouseDown +=new System.Windows.Forms.MouseEventHandler (this.MainForm_MouseDown);

		    this.MouseUp+=new System.Windows.Forms.MouseEventHandler(this.MainForm_MouseUp );

		    this.MouseMove+=new System.Windows.Forms.MouseEventHandler(this.MainForm_MouseMove);

实现鼠标事件

//具体的委托处理程序实现

		//鼠标按下

		private void MainForm_MouseDown(object sender,System.Windows.Forms.MouseEventArgs e)

		{

			if(e.Button==MouseButtons.Right)

				textBox1.Text="横坐标（X）："+e.X+"   纵坐标(Y):"+e.Y;

		}

		//鼠标移动

		private void MainForm_MouseMove(object sender,System.Windows.Forms.MouseEventArgs e)

		{

			if(e.Button== MouseButtons.Right)

				textBox1.Text="横坐标（X）："+e.X+"   纵坐标(Y):"+e.Y;

		}

		//鼠标放开

		private void MainForm_MouseUp(object sender,System.Windows.Forms.MouseEventArgs e)

		{

			if (e.Button==MouseButtons.Right)

				textBox1.Text="";

		}
