需要帮助来停止BackgroundWorker线程.我试图阻止后台工作线程.这就是我在做的事情:

在停止按钮单击(UI图层):

if (backgroundWorker.IsBusy == true && 
    backgroundWorker.WorkerSupportsCancellation == true)
{
    backgroundWorker.CancelAsync();
}

在DoWork事件(UI层)上:

if ((backgroundWorker.CancellationPending == true))
{
     e.Cancel = true;
}
else
{
    //Function which progresses the progress bar is called 
    //here with its definition in business layer 
}

一旦DoWork事件被触发并且我的程序控件在Business层中定义的函数中,我如何恢复到DoWork事件以设置'e.Cancel = true'？

你能否让我知道以下声明的含义？

S:%B= %B="@1" S:%E= %E="@999"
