html - VB.Net 点击 WebBrowser 中的超链接

Question

如何点击超链接？这不起作用：

       For Each link As HtmlElement In WebBrowser1.Document.links
        If link.Id = "aw0" Then link.InvokeMember("click")
       End If

我也测试过但不起作用：

       For Each link As HtmlElement In WebBrowser1.Document.All
        If link.Id = "aw0" Then link.InvokeMember("click")
       End If

非常感谢您可以给我 html 代码的帮助（在结尾和开头添加 XXX）：
