转换VB 6代码VB.NET

Question

我升级代码从VB 6到VB.NET，和下面的代码给我一个错误：

(VB6.PixelsToTwipsX(mvarPicture.ClientRectangle.Width) - (BDR + X), 
VB6.PixelsToTwipsY(mvarPicture.ClientRectangle.Height) - (BDR + X)), 
mvarBorderColor, 
B 

的错误是：

Error 6 End of statement expected.

任何人都可以帮助我吗？

这是全码：

简短的回答，你少开那些行右括号。

VB.NET不支持长答案，PictureBox.Line()。请查看http://msdn.microsoft.com/en-us/library/9dtfzwyx(v=vs.90).aspx和http://msdn.microsoft.com/en-us/library/system.drawing.graphics.drawline(v=vs.90).aspx了解如何在.NET中执行此操作。
