傳遞參數到WebBrowserDocumentCompleted

Question

比方說，我有一個功能，例如：

public TestStuff() { 

    string testing = "test"; 
    webBrowser2.Navigate("http://google.com"); 
    webBrowser2.DocumentCompleted += WebBrowserDocumentCompleted; 

} 

public WebBrowserDocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs Url) { 

    MessageBox.Show(testing); 
} 

我怎樣才能通過測試進入WebBrowserDocumentCompleted功能？我不確定如何將其添加爲參數。

Answer 1

容易利用closures

public void TestStuff() 
{ 
    string testing = "test"; 
    webBrowser2.DocumentCompleted += (s, e) => 
     { 
      MessageBox.Show(testing); 
     }; 
    webBrowser2.Navigate("http://google.com"); 
} 

Answer 2

試試這個

public TestStuff() 
    { 
     string testing = "test"; 
     webBrowser2.DocumentCompleted += ((WebBrowserDocumentCompletedEventArgs)delegate(object sender, EventArgs args) 
     { 
      evHandler(sender, testing); 
     }); 
     webBrowser2.Navigate("http://google.com"); 

    } 

    public void evHandler(Object sender, string testing) 
    { 
     MessageBox.Show(testing); 
    }
