C# Check The Width and Height of a Image
<p>I am able to display the picture in the picture box without  checking the file size  by the following code.</p>

<pre><code>            private void button3_Click_1(object sender, EventArgs e)
    {

        try
        {
            //Getting The Image From The System
            OpenFileDialog open = new OpenFileDialog();
            open.Filter = "Image Files(*.jpg; *.jpeg; *.gif; *.bmp)|*.jpg; *.jpeg; *.gif; *.bmp";
            if (open.ShowDialog() == DialogResult.OK)
            {
                Bitmap img = new Bitmap(open.FileName);



                    pictureBox2.Image = img;

            }
        }   
        catch (Exception)
        {
            throw new ApplicationException("Failed loading image");
        }

    }
</code></pre>
