Label变成有渐变背景色的圆角矩形

设置Label的属性BorderStyle = None;//这样才能看到效果

在Label的Paint事件里调用如下方法：

private void label_Paint(object sender, PaintEventArgs e)
{
DrawRoundRect(e.Graphics, label);
DrawString(e.Graphics, label);
}

private void DrawRoundRect(Graphics graphics, Label label)
{
float X = float.Parse(label.Width.ToString()) - 1;
float Y = float.Parse(label.Height.ToString()) - 1;
PointF[] points = {
new PointF(2,0),
new PointF(X-2,0),
new PointF(X-1,1),
new PointF(X,2),
new PointF(X,Y-2),
new PointF(X-1,Y-1),
new PointF(X-2,Y),
new PointF(2,Y),
new PointF(1,Y-1),
new PointF(0,Y-2),
new PointF(0,2),
new PointF(1,1)
};

GraphicsPath path = new GraphicsPath();
path.AddLines(points);

Pen pen = new Pen(Color.FromArgb(150, Color.Gray), 1);
pen.DashStyle = DashStyle.Solid;
graphics.DrawPath(pen, path);

PathGradientBrush p = new PathGradientBrush(path);
p.CenterColor = Color.White;
Color[] color = { Color.LightGray };
p.SurroundColors = color;
graphics.FillPath(p, path);
}

private void DrawString(Graphics graphics, Label label)
{
Font font = new Font("宋体", 10.0f, FontStyle.Regular);
StringFormat stringFormat = new StringFormat();
stringFormat.Alignment = StringAlignment.Center;
stringFormat.LineAlignment = StringAlignment.Center;
Brush brush = new SolidBrush(Color.Black);
RectangleF rect = new RectangleF(0, 0, label.Width, label.Height);
graphics.DrawString(label.Text, font, brush, rect, stringFormat);
}
