c# - 将参数传递到 WebBrowserDocumentCompleted

Question

假设我有这样一个函数:

public TestStuff() {

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

}

public WebBrowserDocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs Url) {

    MessageBox.Show(testing);
}

如何将测试传递给 WebBrowserDocumentCompleted 函数？我不确定语法上如何将它添加为参数。

Answer 1

使用 closures 很容易

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