C#

public void DrawRectangle(System.Drawing.Pen pen, int x, int y, int width, int height);

Parameters

pen

Pen

Pen that determines the color, width, and style of the rectangle.

x

Int32

The x-coordinate of the upper-left corner of the rectangle to draw.

y

Int32

The y-coordinate of the upper-left corner of the rectangle to draw.

width

Examples

The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e, which is a parameter of the Paint event handler. The code performs the following actions:

• Creates a black pen.

• Creates the position and size of a rectangle.

• Draws the rectangle to the screen.

C#

public void DrawRectangleInt(PaintEventArgs e)
{
             
    // Create pen.
    Pen blackPen = new Pen(Color.Black, 3);
             
    // Create location and size of rectangle.
    int x = 0;
    int y = 0;
    int width = 200;
    int height = 200;
             
    // Draw rectangle to screen.
    e.Graphics.DrawRectangle(blackPen, x, y, width, height);
}
