C# winform 实现弹出的等待对话框实例

在Form1窗体中(主窗体) 
private void button1_Click(object sender, EventArgs e) 
{ 
Form2 f = new Form2(); 
f.ShowDialog(this); 
} 


在Form2窗体中(弹出窗体) 
using System.Threading; 

//线程对象 
Thread tWork ; 

//退出标志 
bool bExit = false; 

//当页面加载时开始线程 
private void Form2_Load(object sender, EventArgs e) 
{ 
tWork = new Thread(new ThreadStart(Work)); 
tWork.Start(); 
} 
// 
void Work() 
{ 
int i = 0; 
while (!bExit) 
{ 
i++; 

Thread.Sleep(1); 
if (i > 100) break; 

} 
this.BeginInvoke(new EventHandler(WorkOver), new object[] { null,null}); 
} 
//点击取消退出 
private void button1_Click(object sender, EventArgs e) 
{ 
bExit = true; 
if (tWork.Join(1000) == false) 
{ 
tWork.Abort(); 
} 
Close(); 
} 
//当工作结束 
private void WorkOver(object sender, EventArgs e) 
{ 
Close(); 

}
