执行与单一的点击两个按钮 [英] Execute two buttons with single click

问题描述

我有一个包含按钮的简单的C＃应用​​程序和网络浏览器，每个按钮执行请求，并显示在网络浏览器的请求的结果。并利用一个请求的结果中的下一个按钮。

I have a simple C # application that contains buttons and a web browser, each button execute a request and displays the result of the request on the web browser. And use the results of a request in the next button.

private void button1_Click(object sender, EventArgs e)
        {
webBrowser1.Navigate("http://www.test.com");
}

private void button2_Click(object sender, EventArgs e)
        {
            if (webBrowser1.Document.GetElementById("tesxtbox1") != null)
            {
            HtmlElement txt1 = webBrowser1.Document.GetElementById("tesxtbox1");
            txt1.SetAttribute("value", "test");
            webBrowser1.Document.Forms[0].InvokeMember("submit");
            }
        }

有没有任何方法或与一个单一的点击执行两个按钮的方式，但第二个按钮，直到Web浏览器加载不执行。

Is there any method or way to perform the two buttons with a single click, but the second button, do not execute until the web browser is loaded.

在第一个按钮，我添加

webBrowser1.DocumentCompleted + = new WebBrowserDocumentCompletedEventHandler (Button2_Click);

但第二个按钮excuted几次，所以在最后一行添加的按钮2：

but the second button excuted several times, so I added in the last line of the button 2:

webBrowser1.DocumentCompleted - = new WebBrowserDocumentCompletedEventHandler (Button2_Click);

它的工作原理，但在控制台中我发现，按钮2次执行

it works, but in the console I find that Button 2 is execute twice

在此先感谢！

推荐答案

您应该添加将调用code，一旦该文件已完成加载的事件。

You should add an event that will call the code once the document has completed loading.

private void Form1_Load(object sender, EventArgs e)
{
    webBrowser1.DocumentCompleted += webBrowser1_DocumentCompleted;
}    

void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    button2_Click(sender, e);
}
