在后台进程DoWork（）后，控件从块中退出，但它从不触发RunWorkerCompleted（），还有一件事是isBusy仍然是真的
请帮帮我
Dispatcher.CurrentDispatcher.Invoke(new Action(() =>
{
sendFile.Send();
}));
这是我的FileReadWrite.cs文件 每当我在xaml类文件中使用此文件时它都可以工作但是我在WindowBase.dll的DispatcherObject类中使用Dispatcher但在另一个.cs文件中我不能使用DispatcherObject类，这就是我使用Dispatcher的原因.CurrentDispatcher.Invoke（）
