C#使用System.Timers.Timer类实现一个Button锁定功能（windows form）

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
Control.CheckForIllegalCrossThreadCalls = false;//消除异常：Cross-thread operation not valid:Control 'button1' accessed from a thread other than the thread it was created on .
}
System.Timers.Timer t = new System.Timers.Timer(5000);

private void button1_Click(object sender, EventArgs e)
{
MessageBox.Show("This Button has been locked");
t.Start();
t.AutoReset = false;
t.Enabled = true;
button1.Enabled = false;
t.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed);

}
private void  timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
t.Stop();
this.button1.Enabled = true;//必须加上Control.CheckForIllegalCrossThreadCalls = false;否则报异常：Cross-thread operation not valid:Control 'button1' accessed from a thread other than the thread it was created on .
}
private void button2_Click(object sender, EventArgs e)
{
MessageBox.Show(Owner,"OK");
}
