           int row = txtViewer.GetLineIndexFromCharacterIndex(txtViewer.CaretIndex);
           int col = txtViewer.CaretIndex - txtViewer.GetCharacterIndexFromLineIndex(row);
          lblCursorPosition.Text = "line" + (row + 1) + ",char" + (col + 1);
        }
    }
}

推荐答案

您好使用以下代码，

Hi use the following code,

Application.Current.Dispatcher.Invoke(DispatcherPriority.Background,
     (Action)(() =>
     {
         txtViewer.Text += msg;
     }));
