private void Save_Click(object sender, EventArgs e)
{
    //Show a save dialog to allow the user to specify where to save the image file
    using (SaveFileDialog dlgSave = new SaveFileDialog())
    {
        dlgSave.Title = "Save Image";
        dlgSave.Filter = "Bitmap Images (*.bmp)|*.bmp|All Files (*.*)|*.*";
        if (dlgSave.ShowDialog(this) == DialogResult.OK)
        {
            //If user clicked OK, then save the image into the specified file
            using (Bitmap bmp = new Bitmap(pictureBox1.Width, pictureBox1.Height))
            {
                picturebox1.DrawToBitmap(bmp, new Rectangle(0, 0, bmp.Width, bmp.Height));
                bmp.Save(dlgSave.FileName);
            }
        }
    }

Hi madhu

Try this code:

If you want to save the image that is displayed in the picture box, complete with any lines that may have been drawn on top of it during run-time, you can use the Control.DrawToBitmap method

Here's an example of a complete solution. First, the user is prompted by a save dialog (entitled "Save Image" and filtering to bitmap images (*.bmp) by default). If they click OK, the image displayed in the picture box is drawn to a temporary bitmap, and that temporary bitmap is saved to the location they specified. If they click Cancel, the file is not saved and the method simply exits.
