Dragable rectangles

[Dumpen]

Hello.

I have a question..

I have this script:
int mouseDownX;
int mouseDownY;

int width;
int height;

private void Form1_MouseUp(object sender, MouseEventArgs mouseEv)
{
width = mouseEv.X - mouseDownX;
height = mouseEv.Y - mouseDownY;

textBox2.Text = Convert.ToString(mouseEv.Location);

Graphics graphics = this.CreateGraphics();

Rectangle rectangle = new Rectangle(
mouseDownX, mouseDownY, width, height);

graphics.DrawRectangle(Pens.Red, rectangle);
}

private void Form1_MouseDown(object sender, MouseEventArgs mouseEv)
{
textBox1.Text = Convert.ToString(mouseEv.Location);

mouseDownX = mouseEv.X;
mouseDownY = mouseEv.Y;
}

Which works fine if I make a rectangle from the left top corner to the right bottom corner

But is there any easier way of just making rectangles?

Here is a video of what I want:

And here is a download link to my project:

So I want to be able to draw rectangles from any angle if you understand?
