推荐答案

您必须将复制循环移至其自己的线程.
最简单的方法是使用backgroundworker.
代码项目中有一个示例:
BackgroundWorker线程和支持取消 [

You have to move the copy loop to its own thread.
The easiest way to do that is using the backgroundworker.
There is an example here on the code project :
BackgroundWorker Threads and Supporting Cancel[^]

有最简单的方法:

首先定义一个布尔字段:

There is an easiest way:

first define a bool field:

private bool StopLoop = true;

然后将此条件添加到您的循环中:

then add this condition to your loop:

for (int i = 0; i < 30; i++)
{
    if (!StopLoop)
        // Your actions
}

private void Button_Click(object sender, EventArgs e)
{
    StopLoop = false;
}
