示例1: FillEllipseWithPathGradient
public void FillEllipseWithPathGradient(PaintEventArgs e)
{
// Create a path that consists of a single ellipse.
GraphicsPath path = new GraphicsPath();
path.AddEllipse(0, 0, 140, 70);
// Use the path to construct a brush.
PathGradientBrush pthGrBrush = new PathGradientBrush(path);
// Set the color at the center of the path to blue.
pthGrBrush.CenterColor = Color.FromArgb(255, 0, 0, 255);
// Set the color along the entire boundary
// of the path to aqua.
Color[] colors = { Color.FromArgb(255, 0, 255, 255) };
pthGrBrush.SurroundColors = colors;
e.Graphics.FillEllipse(pthGrBrush, 0, 0, 140, 70);
