Get coordinates points between x and y - c# winforms

Question

I have a jpeg image in a picturebox on page load i am drawing the rectangle based on the x(150) and y(440) coordinates. now when i mousemove on the picturebox i need to identify the rectangle by their coordinates and highlight the image. for example see the below image .. lets take the first rectangle on mouse move any points inside the rectangle i need to perform some actions.. how to find the coordinates between these x and y for the rectangle?.. suggest me any ideas Thanks Dev

I have completed my functionality // page level declaration private Rectangle SelectedRect ; public List Rectangle > listRec = new List Rectangle >(); // on page load add all the rectangle in the rectanglelist. private void Highlightimage_Load ( object sender  EventArgs e ) { for ( int i = 0 ; i table . Rows . Count ; i ++) { int x = Convert . ToInt32 ( table . Rows [ i ][ 0 ]); int y = Convert . ToInt32 ( table . Rows [ i ][ 1 ]); int width = Convert . ToInt32 ( table . Rows [ i ][ 2 ]); int height = Convert . ToInt32 ( table . Rows [ i ][ 3 ]); SelectedRect . Size = new Size ( width  height ); SelectedRect . X = x ; SelectedRect . Y = y ; listRec . Add ( SelectedRect ); } } // draw the rectangle private void pictureBox1_Paint ( object sender  PaintEventArgs e ) { Graphics g = e . Graphics ; foreach ( Rectangle rec in listRec ) { Pen p = new Pen ( Color . Red ); g . DrawRectangle ( p  rec ); } } private Rectangle MakeRectangle ( int x0  int y0  int x1  int y1 ) { return new Rectangle ( Math . Min ( x0  x1 ) Math . Min ( y0  y1 ) Math . Abs ( x0 - x1 ) Math . Abs ( y0 - y1 )); } //finally on mouse move checking the condition private void pictureBox1_MouseMove ( object sender  MouseEventArgs e ) { foreach ( Rectangle rec in listRec ) { SelectedRect = MakeRectangle ( rec . Left  rec . Top  rec . Right  rec . Bottom ); if ( ( e . X >= SelectedRect . Left ) && ( e . X SelectedRect . Right ) && ( e . Y >= SelectedRect . Top ) && ( e . Y SelectedRect . Bottom )) { MessageBox . Show ( test ); } } } Thanks Dev

Drag down two labels ... label 1 label 2...change their location properties to 00 protected override void OnMouseClick(MouseEventArgs e) { base.OnMouseClick(e); Graphics g = CreateGraphics(); Pen p = new Pen(Color.Navy); Pen erase = new Pen(Color.White); x = e.X; y = e.Y; label1.Location = new Point(x - label1.Width y); label2.Location = new Point(x y - label2.Height); label1.Text = x.ToString(); label2.Text = y.ToString(); }
