Detecting closest picturebox

Question

I ran into a problem while working on my platform game (once again :D) and i couldn't really found solution for it.. so here is the code:

Blocks.AddRange(this.Controls.OfType<PictureBox>());
if (Blocks.Any(x => x.Location.Y - Player.Height <= Player.Location.Y))
{
    Player.Top = Height - ClosestBlock.Location.Y - Player.Height;
}

and I need to detect which Block is the closest to move player on. If you have any ideas please let me know, Thanks!

What is player, what is block and how they can be related to picture boxes? — Reza Aghaei, Dec 26 '15 at 16:17

Check out the Phytagorean theorem.

If you have two points (x1, y1) and (x2, y2), then the distance between the two are distance = Math.Sqrt(Math.Pow((x2-x1), 2) + Math.Pow(y2-y1),2))

Iterate over all blocks, calculate their center-position (x2, y2) and use the Phytagorean theormen to find the distance between player center-position (x1, y1) and each block (x2n, y2n). Select the block with the shortest distance.
