In this article we are going to see how to draw a elements in the Winforms, To draw the elements we have graphics objects in the paint event. To do the Draw we are using Graphics Path, where we are plotting the points to draw and fill the color. In Graphics path we are adding many elements like line, Ellipse, Curve and Bezier. There is method called Start Figure which will use to draw a figure by the all elements points to finish the figure we have to draw and connect the points by called the CloseFigure(). Finally give the path to the Graphics to draw.

public class AnimatedForm:Form
{
protected override void OnPaint(PaintEventArgs
e)
{
e.Graphics.SmoothingMode = SmoothingMode.AntiAlias;
GraphicsPath path = new
GraphicsPath();
path.StartFigure();
path.AddLine(20, 50, 70, 230);
path.AddArc(30, 60, 70, 140, 130, 120);
path.AddBezier(30, 40, 50, 20, 50, 60, 100, 20);
path.CloseFigure();
path.AddEllipse(60, 50, 180, 180);
PathGradientBrush pgb = new
PathGradientBrush(path);
pgb.SurroundColors = new Color[] { Color.Green,Color.Yellow,Color.Red,
Color.Blue,Color.Orange,
Color.White,
};
e.Graphics.FillPath(pgb, path);
e.Graphics.DrawPath(Pens.Black,
path);
path.Dispose();
path.Dispose();
}
}
public partial class Form1 :AnimatedForm
{
public Form1()
{
InitializeComponent();
}
}
partial class Form1

This programming has the .Net Developer using Elements of Winforms. It's for the graphical analysis with programming.Also Useful for my carrier.
