那位大姐能帮我解决一下个人问题啊:) 我是新手,今天在弄C#的时候,碰到了一个小问题

今天在写一个使用Timer的关于Button的程序,碰到了一个小问题,我搞了一个下午,到现在还没弄出来类.

是这样的:我的程序里面有个button1,我想让程序运行后用定时器实现button1的5秒钟的呈灰色状态;5秒

后button1由灰色状态变为可用.就向某些论坛的账号申请页面,里面用户声明页面的"同意"按钮一样,在X

秒后自动变为可用的功能.

希望各位大人能帮小弟解决一下,在下不胜感激!

就是在哪个OntimedEvent()里面不能使用本类里面定义的变量和函数啊??????
我的代码在下面:

using System;

using System.Drawing;

using System.Collections;

using System.ComponentModel;

using System.Windows.Forms;

using System.Data;

using System.Timers;

namespace UseTimer

{

/// <summary>

/// Form1 的摘要说明。

/// </summary>

public class MyTimer : System.Windows.Forms.Form

{

private System.Windows.Forms.Button button1;

private System.ComponentModel.IContainer components;

private System.Timers.Timer aTimer;

private static int intTimer = 5;

private static string buttonText ;

//private void change();

public MyTimer()

{

//

// Windows 窗体设计器支持所必需的

//

InitializeComponent();

//

// TODO: 在 InitializeComponent 调用后添加任何构造函数代码

//

}

/// <summary>

/// 清理所有正在使用的资源。

/// </summary>

protected override void Dispose( bool disposing )

{

if( disposing )

{

if (components != null)

{

components.Dispose();

}

}

base.Dispose( disposing );

}

#region Windows 窗体设计器生成的代码

/// <summary>

/// 设计器支持所需的方法 - 不要使用代码编辑器修改

/// 此方法的内容。

/// </summary>

private void InitializeComponent()

{

this.button1 = new System.Windows.Forms.Button();

this.aTimer = new System.Timers.Timer();

((System.ComponentModel.ISupportInitialize)(this.aTimer)).BeginInit();

this.SuspendLayout();

//

// button1

//

this .button1 .Location = new System.Drawing.Point(96, 96);

this .button1 .Name = "button1";

this .button1 .TabIndex = 1;

this .button1 .Text = "确定(5)";

//

// aTimer

//

this.aTimer.Enabled = true;

this.aTimer.Interval = 1000;

this.aTimer.SynchronizingObject = this;

//

// MyTimer

//

this.AutoScaleBaseSize = new System.Drawing.Size(6, 14);

this.ClientSize = new System.Drawing.Size(292, 268);

this.Controls.Add(this.button1 );

this.Name = "MyTimer";

this.Text = "MyTimer";

this.Load += new System.EventHandler(this.MyTimer_Load);

((System.ComponentModel.ISupportInitialize)(this.aTimer)).EndInit();

this.ResumeLayout(false);

}

#endregion

/// <summary>

/// 应用程序的主入口点。

/// </summary>

[STAThread]

static void Main()

{

Application.Run(new MyTimer ());

}

private void MyTimer_Load(object sender, System.EventArgs e)

{

this.button1 .Enabled = false;

}

private void timer1_Tick(object sender, System.EventArgs e)

{

}

private static void OnTimedEvent(object source, ElapsedEventArgs e)

{

if ( MyTimer.intTimer >0)

{

MyTimer.buttonText = MyTimer.intTimer .ToString ();

MyTimer.intTimer --;

this.button1.Text ="确定(" + buttonText + ")";

}

else

{

this.button1.Enabled = true;

this.button1.Text = "确定";

}

}

}

}
