推荐答案

一个的哈克的办法是：

1. 附加一个事件处理程序的按钮的onclick事件。


2. 然后，一旦该事件被触发时，使用的 Microsoft Internet控制（SHDOCVW）的类型库，以获得在IE中打开过的网址。


3. 最后，导航到网址，一旦文件被加载，您可以通过 webBrowser1.DocumentText 属性文件的来源。

1. Attach an event handler to the 'onclick' event of the button.
2. Then, once the event is triggered, use the Microsoft Internet Controls (SHDocVw) type library in order to get the last URL opened in IE.
3. Lastly, navigate to the URL and once the document is loaded, get the source of the document from the webBrowser1.DocumentText property.

在你的项目中，添加到的 Microsoft Internet控制的参考的类型库（你会在 COM 的标签找到它）。加入你的文件的顶部：

In your project, add a reference to the Microsoft Internet Controls type library (you'll find it in the COM tab). Add at the top of your file:

using SHDocVw;

在code：

webBrowser1.Navigate(url);
while (webBrowser1.ReadyState != WebBrowserReadyState.Complete)
{
    Application.DoEvents();
}

// assign the button to a variable
var button = webBrowser1.Document.GetElementById("downloadButton");

// attach an event handler for the 'onclick' event of the button
button.AttachEventHandler("onclick", (a, b) =>
{
    // use the Microsoft Internet Controls COM library
    var shellWindows = new SHDocVw.ShellWindows();

    // get the location of the last window in the collection
    var newLocation = shellWindows.Cast<SHDocVw.InternetExplorer>()
        .Last().LocationURL;

    // navigate to the newLocation
    webBrowser1.Navigate(newLocation);
    while (webBrowser1.ReadyState != WebBrowserReadyState.Complete)
    {
        Application.DoEvents();
    }

    // get the document's source
    var source = webBrowser1.DocumentText;
});

button.InvokeMember("click");
