我在做一个项目，我在 vb.net 中遇到了关于 webbrowser 工具的障碍。当用户在特定站点时，我想显示一个 msgbox，如何做到这一点？，换句话说，如何在 vb.net 的 webberowser 工具中获取当前 url？

Webbrowser.Urlis a Uri, not a string. So compare it with a Uri.
Webbrowser.Url是一个Uri，而不是一个字符串。因此，将其与Uri.
If WebBrowser1.Url = New Uri("http://stackoverflow.com") Then

I would say you should check the Host of the URI, that way it works for all of the URLs and not just the top level for a given site:
我会说你应该检查 URI 的主机，这样它适用于所有 URL，而不仅仅是给定站点的顶级：
Private Sub Button1_Click_1( sender As System.Object, e As System.EventArgs) Handles Button1.Click
WebBrowser1.Navigate("http://www.stackoverflow.com")
End Sub
Private Sub WebBrowser1_DocumentCompleted( sender As System.Object, e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
If WebBrowser1.Url.Host = "stackoverflow.com"
MessageBox.Show("You are at stack overflow")
End If
End Sub

Is this what you mean?
你是这个意思吗？
Dim browser As String
browser = TextBox1.Text
WebBrowser1.Navigate(browser)
MsgBox("Your visiting " & browser)
End Sub
