我现在有段代码可以实现分左右来绘制背景色,请问怎么实现上下来绘制背景色(代码来源于网络)
// Getting the graphics object
Graphics g = pevent.Graphics; // Creating the rectangle for the gradient
Rectangle rBackground = new Rectangle(0, 0, this.Width, this.Height); // Creating the lineargradient
System.Drawing.Drawing2D.LinearGradientBrush bBackground
= new System.Drawing.Drawing2D.LinearGradientBrush(rBackground, _Color1, _Color2, _ColorAngle); // Draw the gradient onto the form
g.FillRectangle(bBackground, rBackground);
// Disposing of the resources held by the brush
bBackground.Dispose();
