}你试试可以不？

楼主，进度条有一个最大的值，你在每次增加value的时候就检测一下这个值，达到后就触发指定函数

ProgressBar1.Maximum = 100;
ProgressBar1.Value = 1; 
timer21Start();  
private void timer1_Tick(object sender, EventArgs e) 
{ 
  ProgressBar1.Value --; 
  this.progressBar1.Update(); 
}

顶一楼的，写的很好，在timer事件中加上if 判断语句就行，满足了就直接调用你想要执行按钮事件

progressBar1.Value== progressBar1.Maximum)触发事件
