How to get the position of a Click?

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?

In your click handler, do:

MousePosition.X
MousePosition.Y

Example:

// 
// pictureBox1 Init
// 
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 only receives MouseUp and MouseDown. A MouseClick can't receive your coordinates, because a click consists of a MouseUp and a MouseDown, and both can have different coordinates.

One more solution (I think this is 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;
}

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));
}

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