Question

我的项目中有一个WebBrowser从txt文件中读取信息...（只有1行）...但每次打开程序时，浏览器都在重新加载（如循环）url位于url.txt这里是代码：

    Private Sub WebBrowser1_DocumentCompleted_1(sender As Object, e As WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
    Dim url As String = "url.txt"
    Dim objReader As New System.IO.StreamReader(url)
        WebBrowser1.Navigate(objReader.ReadLine)
        objReader.Close()
End Sub

如果有人能帮助我，我会感激的。

尝试更改要加载URL的事件处理程序。现在，当WebBrowser完成加载文档时，您正在执行此操作。因此，每次完成加载，它都会再次执行。我怀疑你真的想在表单加载时这样做：

Private Sub Form1_Load(sender As Object, e As WebBrowserDocumentCompletedEventArgs) Handles Form1.Load
    Dim url As String = "url.txt"
    Dim objReader As New System.IO.StreamReader(url)
    WebBrowser1.Navigate(objReader.ReadLine)
    objReader.Close()
End Sub

Web浏览器从txt文件循环url ...
