投不使用的BackgroundWorker时有效

Question

我已经从我的Form_Load代码BackgroundWorker的，但它说，“指定的转换无效”，上传这里：My Codes Image

    Private Sub FirstRunWorker_DoWork(sender As Object, e As System.ComponentModel.DoWorkEventArgs) Handles FirstRunWorker.DoWork
    Dim url1 As String = publicurl & "index.php"
    Dim datavillages1 As String = TGet("", url1, url1, My.Settings.useragent)
    If datavillages1.Contains("error") Then
        'ADD LOG
    Else
        wb.DocumentText = datavillages1
        While wb.ReadyState <> WebBrowserReadyState.Complete
            Application.DoEvents()
        End While
    End If
End Sub
