让文件系统监视器事件发生在主UI线程上

Question

我可以让文件系统监视器事件发生在主UI线程上吗?

Answer 1

简单地设置FileSystemWatcher。将SynchronizingObject属性添加到表单实例。与调用BeginInvoke()相同，但会自动为您完成。样板代码:

public Form1() {
    InitializeComponent();
    fileSystemWatcher1.SynchronizingObject = this;
}

Answer 2

this.BeginInvoke((MethodInvoker)(() => SomeMethod())); // Check files in the Main thread otherwise threading issues occur
