Question

我希望能够打开网页，登录，并能够在下一页上执行操作。 DoPlans不会执行。到目前为止，这是我的代码...（我知道我有很多变量）

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
        webBrowser1.Navigate("t");
    }

    private void DoPlans(object sender,
WebBrowserDocumentCompletedEventArgs e)
    {
        textBox1.AppendText("started");
        webBrowser1.Document.GetElementById("t").InvokeMember("Click");
        webBrowser1.Document.GetElementById("t").InvokeMember("Click");
        foreach (HtmlElement elem in webBrowser1.Document.GetElementsByTagName("input"))
        {
            if (elem.GetAttribute("value") == "Submit Weekend Plans")
            {
                elem.InvokeMember("Click");
            }
        }
    }

    private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
    {
        webBrowser1.Document.GetElementById("username").SetAttribute("value", "t");
        webBrowser1.Document.GetElementById("password").SetAttribute("value", "t");
        foreach (HtmlElement elem in webBrowser1.Document.GetElementsByTagName("input"))
        {
            if (elem.GetAttribute("value") == "Login")
            {
                webBrowser1.DocumentCompleted += new WebBrowserDocumentCompletedEventHandler(DoPlans);
                elem.InvokeMember("Click");
            }
        }
    }
}

尝试这样的事情：

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    switch (e.Url.ToString())
    {
        case "home page":
        {
            // fire click
            break;
        }
        case "next page":
        {
            // handle logged in user
            break;
        }
    }
}
