How I can do drawing through any event ? like button click or function

public partial class Form1 : Form
    {

        public int xcoordinate = 0;
        public int ycoordinate = 0;
        public int ESD_no = 2;
        public int IntertripESD = 0;
        public bool MenuClickdone = false;
        //private Bitmap MyImage;

        public event System.Windows.Forms.MouseEventHandler MouseClick;
        public void ShowMyimage(string WorkingDirectory, int xsize,int ysize)
                    {
           // WorkingDirectory = @"C:\PhotoXv";
            WorkingDirectory = @"C:\Users\abuhmammACER\source\repos\PhotoXv\xv_close.png";
            Bitmap xv_close = new Bitmap(WorkingDirectory);
            // xv_close = Image.FromFile(@"C:\PhotoXv\xv_close.png");
           // Image xv_open = Image.FromFile(WorkingDirectory + @"\xv_open.png");
           //// if (MyImage !=null )
           // {
            //    MyImage.Dispose();
           // }
            int sourceWidth = xv_close.Width;
            int sourceHeight = xv_close.Height;
            

            //Bitmap bmPhoto = new Bitmap(sourceWidth,sourceHeight);
            Graphics GraphicPhoto = Graphics.FromImage(xv_close);

            GraphicPhoto.DrawImage(xv_close, xsize, ysize,sourceWidth,sourceHeight);
            //GraphicPhoto.Save("output.png", ImageFormat.Png);
           // GraphicPhoto.Save( ImageFormat.Png);
        }

private void button1_Click(object sender, EventArgs e)
        {
            //this.Paint += new PaintEventHandler(Image_fun);
            
            ShowMyimage(@"C:\Users\abuhmammACER\source\repos\PhotoXv\xv_close.png", 40, 50);
           // f1_paint(object sender, PaintEventArgs e);
        }
