推荐答案

在UserControl中设置一个公共方法，该方法调用一个事件，然后从表单中调用该方法.

Make a public method in your UserControl which invokes an event, then call that method from your form.

您的问题不清楚.我认为您想以父表单处理事件，而不是从父表单引发事件.发布您的代码可能会有所帮助.但这是一个一般准则.

要以父形式处理用户控件事件，请将控件的事件连接到父形式中的方法，如下所示:

Your question is not clear. I think you want to handle the event in the parent form rather than raise it from the parent form. Posting your code might help. But here is a general guideline.

To handle user control events in the parent form, hook up the control''s event to a method in the parent form like this:

private void Form1_Load(......) {
    userControl1.MyEvent+=new EventHandler(UserControl1_MyEvent);
}

private void UserControl1_MyEvent(......) {
    //Do stuff here
}
