错误 1 当前上下文中不存在名称“Mouse_x” C:\Documents and Settings\user\My Documents\Visual Studio 2005\Projects\ScreenCutter\ScreenCutter\ScreenBody.cs 63 31 ScreenCutter
错误 2 当前上下文中不存在名称“Mouse_y” C:\Documents and Settings\user\My Documents\Visual Studio 2005\Projects\ScreenCutter\ScreenCutter\ScreenBody.cs 63 40 ScreenCutter

Answer 1

DrawRect(Painter, Mouse_x, Mouse_y);
改成
DrawRect(Painter, Rect.X, Rect.Y);
