主题：[讨论]FileManager控件中文件打开后能不能加上水印

这样写

    g.DrawString(msg,fnt,Brushes.Red,new RectangleF(30, 100, 100, 100))
    g.DrawString(msg,fnt,Brushes.Red,new RectangleF(60, 200, 100, 100))
    g.DrawString(msg,fnt,Brushes.Red,new RectangleF(90, 300, 100, 100))   

或者这样写

For x As Integer = 30 To 90 Step 30
    For y As Integer = 100 To 300 Step 100
        g.DrawString(msg,fnt,Brushes.Red,new RectangleF(30, 100, 100, 100))
    Next
