Question

我没有想法......

大家好，我对C＃和Html Documents / Elements几乎一无所知，使用DocumentCompleted时发生了一些奇怪的事情。这是DocumentCompleted代码和PostGame（）代码：

    private void WB_CHL_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
    {
        if (Date != "")
            PostGame();
        else
            this.Close();
    }

    private void PostGame()
    {
        HtmlDocument doc = null;
        doc = WB_CHL.Document;

        HtmlElementCollection inputelems = doc.GetElementsByTagName("input");
        inputelems.GetElementsByName("subject")[0].SetAttribute("value", Date);

        doc.GetElementById("text_editor_textarea").SetAttribute("value", Games);

        HtmlElementCollection inputbutton = doc.GetElementsByTagName("input");
        inputbutton.GetElementsByName("post")[0].Focus();
        SendKeys.Send("{ENTER}");
    }

以下是HTML源代码：

所以问题是在执行帖子之前必须调用DocumentCompleted / PostGame（）函数4次。

第一回合：遇到此行时，会抛出异常

    inputelems.GetElementsByName("subject")[0].SetAttribute("value", Date);

    System.ArgumentOutOfRangeException: Value of '0' is not valid for 
    'index'. 'index' should be between 0 and -1.
    Parameter name: index

第二回合：第一回合发生同样的事情

第3回合：浏览所有PostGame（）函数，但不会在论坛上发布。（这部分代码似乎没有很好地切换）

    HtmlElementCollection inputbutton = doc.GetElementsByTagName("input");
    inputbutton.GetElementsByName("post")[0].Focus();
    SendKeys.Send("{ENTER}");

第4回合：浏览所有PostGame（）函数并在论坛上正确发布。

我对此都很陌生......我已经尝试调试并找到问题超过3个小时而无法找到它们/他们......请帮帮我!!!

谢谢你们！

Answer 1

您没有发布完整的HTML，但我可以说它包含一些iframe。 < - 1}}在文件加载完毕后会被调用。

但是如果HTML中有多个DocumentCompleted，那么您有多个文档。

因此，当每个iframe完成加载它所指向的文档时，它会被多次调用。

您可以检查事件处理程序中iframe参数的Url属性，以查看加载的文档。如果您只想处理主页面加载，您应该可以使用：

WebBrowserDocumentCompletedEventArgs

webBrowser_DocumentCompleted无缘无故地调用4次（我可以找到）
