C＃传递一个委托作为参数

Question

我知道我可以这样做：

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

但是有没有办法可以将内联委托作为参数传递？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，除非您无法调用参数事件。我也会使用lambda表达式，因为它更好。

DoRequest（“some_data”，（o，e）=＆gt; {/ *处理事件* /}）;

Answer 2

是的，除了event是关键字且不能用作变量名之外，您可以完全写出来。
