            Graphics g = panel1.CreateGraphics();//创健控件的Graphics类
            g.Clear(Color.White);//以指定的颜色清除控件背景
            Color Var_Color_Up = Color.Purple ;//设置前景色

            Font Var_Font = new Font("宋体", 40);//设置字体样式
            string Var_Str = "有暗香盈袖";//设置字符串
            SizeF Var_Size = g.MeasureString(Var_Str, Var_Font);//获取字符串的大小
            PointF Var_Point = new PointF(5, 5);
            RectangleF Var_Rect = new RectangleF(Var_Point, Var_Size);
            LinearGradientBrush Var_LinearBrush = new LinearGradientBrush(Var_Rect, Var_Color_Up, Var_Color_Down, LinearGradientMode.Horizontal);
            g.DrawString(Var_Str, Var_Font, Var_LinearBrush, Var_Point);
