How to get the position of a Click?

Question

I'm currently making a game where the player will click on one of his units (which are pictureboxes) and a circle will become visible with the player's unit in the center. (Circle is also a picturebox) When the player clicks on the picturebox of the circle I need to figure out if the position of the click is inside the radius of the circle. My question is how do I get the position of the click?

Answer 1

In click handler do:

   MousePosition.X
   MousePosition.Y

Add example:

        // 
        // pictureBox1 Init
        // 
        this.pictureBox1.Location = new System.Drawing.Point(1, 1);
        this.pictureBox1.Name = "pictureBox1";
        this.pictureBox1.Size = new System.Drawing.Size(100, 100);
        this.pictureBox1.Click += new System.EventHandler(this.pictureBox1_Click);

..........................................

    private void pictureBox1_Click(object sender, EventArgs e)
    {
        MessageBox.Show(string.Format("X: {0} Y: {1}", MousePosition.X, MousePosition.Y));
    }

Shows: "X: 537 Y: 946"

One more thing:

The MouseEventArgs with coordinates receive only MouseUp and MouseDown.

MouseClick can't recive you cordinates because click consists from MouseUp and MouseDown and it both can have different coordinates.

One more solution (Think it best)

    private int X;
    private int Y;

    private void pictureBox1_Click(object sender, EventArgs e)
    {
        MessageBox.Show(string.Format("X: {0} Y: {1}", X, Y));
    }

    private void pictureBox1_MouseUp(object sender, MouseEventArgs e)
    {
        X = e.X;
        Y = e.Y;
    }

Answer 2

use the MouseClick event of the PictureBox for this sort of thing...

With Yahia's answer, I learned that the EventArgs can be cast to MouseEventArgs.

private void pictureBox1_Click(object sender, EventArgs e)
{
    MouseEventArgs e2 = (MouseEventArgs) e;
    MessageBox.Show(string.Format("X: {0} Y: {1}", e2.X, e2.Y));
}
