c# ERROR while insert into database ms. access : i have a problem. i want to load image file or rar/zip to my WPF. when i click button on my WPF to open file dialog, i got some errors. 

this is my code to open file dialog.

    private void button1_Click(object sender, EventArgs e)
        {

            try
            {
                
                op.Title = "Select a File";
                op.Filter = "All supported graphics|*.jpg;*.jpeg;*.png|" +
                            "JPEG (*.jpg;*.jpeg)|*.jpg;*.jpeg|" +
                            "Portable Network Graphic (*.png)|*.png"+
                            "Zip Files|*.zip;*.rar";
                if (op.ShowDialog() == DialogResult.OK)
                {
                    
                        pictureBox1.Image = System.Drawing.Image.FromFile(op.FileName);
                        _path = op.FileName;
                        pictureBox1.SizeMode = PictureBoxSizeMode.StretchImage;
                    
                    
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }



        }

my question is how to show image if file format is .jpg / .png, and show rar icon if file format is .rar / .zip in picturebox.
