C#-从浏览器中删除事件 [英] C# - Remove Event From Browser

问题描述

我将一个事件添加到 webBrowser 中，如下代码:

I add an event to webBrowser as below code:

webBrowser.DocumentCompleted += (s, e) => {};

现在如何删除此事件?这样的事情:

Now How can I remove this event inside of it? Somthing like this:

webBrowser.DocumentCompleted += (s, e) => {
webBrowser.DocumentCompleted -= this;
};

推荐答案

您只需要引用您的委托即可.像这样:

You just need a reference to your delegate. Something like this:

WebBrowserDocumentCompletedEventHandler complete = null;
complete = (s, e) => {
    webBrowser.DocumentComplete -= complete;
};
webBrowser.DocumentComplete += complete;
