请问下这个怎么回事?

private void DrawRect(Graphics Painter, int Mouse_x, int Mouse_y)
{
int width = 0;
int heigth = 0;
if (Mouse_y < Rect.Y)
{
Rect.Y = Mouse_y;
heigth = downPoint.Y - Mouse_y;
}
else
{
heigth = Mouse_y - downPoint.Y;
}
if (Mouse_x < Rect.X)
{
Rect.X = Mouse_x;
width = downPoint.X - Mouse_x;
}
else
{
width = Mouse_x - downPoint.X;
}
Rect.Size = new Size(width, heigth);
Painter.DrawRectangle(pen, Rect);
}

private Image DrawScreen(Image back, int Mouse_x, int Mouse_y)
{
Graphics Painter = Graphics.FromImage(back);
DrawRect(Painter, Mouse_x, Mouse_y);
return back;
}
private void MoveRect(Image image, Rectangle Rect)
{
Graphics Painter = Graphics.FromImage(image);
Painter.DrawRectangle(pen, Rect.X, Rect.Y, Rect.Width, Rect.Height);
DrawRect(Painter, Mouse_x, Mouse_y);
MainPainter.DrawImage(image, 0, 0);
image.Dispose();
}


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

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

查找
Application.Run(new Form1());
改为其他form

原本是下面代码
private void DrawRect(Graphics Painter, int Mouse_x, int Mouse_y)
{
int width = 0;
int heigth = 0;
if (Mouse_y < Rect.Y)
{
Rect.Y = Mouse_y;
heigth = downPoint.Y - Mouse_y;
}
else
{
heigth = Mouse_y - downPoint.Y;
}
if (Mouse_x < Rect.X)
{
Rect.X = Mouse_x;
width = downPoint.X - Mouse_x;
}
else
{
width = Mouse_x - downPoint.X;
}
Rect.Size = new Size(width, heigth);
Painter.DrawRectangle(pen, Rect);
}

private Image DrawScreen(Image back, int Mouse_x, int Mouse_y)
{
Graphics Painter = Graphics.FromImage(back);
DrawRect(Painter, Mouse_x, Mouse_y);
return back;
}
private void MoveRect(Image image, Rectangle Rect)
{
Graphics Painter = Graphics.FromImage(image);
Painter.DrawRectangle(pen, Rect.X, Rect.Y, Rect.Width, Rect.Height);
DrawRects(Painter);
MainPainter.DrawImage(image, 0, 0);
image.Dispose();
}
