C# 将委托(delegate)作为参数传递

Question

我知道我可以做到这一点:

WebClient client = new WebClient();client.UploadStringCompleted += delegate(object sender, UploadStringCompletedEventArgs e){    //handle event};client.UploadStringAsync(myURI, "POST", "some_data");

但是有没有一种方法可以将内联委托(delegate)作为参数传递？像这样:

DoRequest("some_data",    delegate(object sender, UploadStringCompletedEventArgs e)    {        //handle event    });public void DoRequest(string data, UploadStringCompletedEventHandler event){    WebClient client = new WebClient();    client.UploadStringCompleted += event;    client.UploadStringAsync(myURI, "POST", data);}

Answer 1

是的，该代码是正确的，只是您不能调用您的参数事件。我也会改用 lambda 表达式，因为它更好。

DoRequest("some_data", (o, e) => {/* 处理事件 */});
