PictureBox Image is a property  not a method  You can set it like this   PictureBox1 Image   System Drawing Image FromFile dlg FileName

You have to create an instance of the Bitmap class  using the constructor overload that loads an image from a file on disk  As your code is written now  you re trying to use the PictureBox Image property as if it were a method   Change your code to look like this  also taking advantage of the using statement to ensure proper disposal  rather than manually calling the Dispose method    private void button1 Click object sender  EventArgs e           Wrap the creation of the OpenFileDialog instance in a using statement         rather than manually calling the Dispose method to ensure proper disposal     using  OpenFileDialog dlg   new OpenFileDialog                  dlg Title    Open Image           dlg Filter    bmp files    bmp    bmp            if  dlg ShowDialog      DialogResult OK                        PictureBox PictureBox1   new PictureBox                    Create a new Bitmap object from the picture file on disk                 and assign that to the PictureBox Image property             PictureBox1 Image   new Bitmap dlg FileName                       Of course  that s not going to display the image anywhere on your form because the picture box control that you ve created hasn t been added to the form  You need to add the new picture box control that you ve just created to the form s Controls collection using the Add method  Note the line added to the above code here   private void button1 Click object sender  EventArgs e        using  OpenFileDialog dlg   new OpenFileDialog                  dlg Title    Open Image           dlg Filter    bmp files    bmp    bmp            if  dlg ShowDialog      DialogResult OK                        PictureBox PictureBox1   new PictureBox                PictureBox1 Image   new Bitmap dlg FileName                   Add the new control to its parent s controls collection             this Controls Add PictureBox1

You should try to      Create the picturebox visually in form  it s easier  Set Dock property of picturebox to Fill  if you want image to fill form  Set SizeMode of picturebox to StretchImage   Finally   private void button1 Click object sender  EventArgs e        OpenFileDialog dlg   new OpenFileDialog        dlg Title    Open Image       dlg Filter    bmp files    bmp    bmp       if  dlg ShowDialog      DialogResult OK                                     PictureBox1 Image   Image FromFile dlg Filename             dlg Dispose
