C#: Print Screen or Take Screenshot

Lately, I was building a simple add-on that will capture the user screen and automatically send it to the system administrator. This add-on will be plug-in into our existing systems. It will be automatically triggered if an error is detected so the system administrator can analyze the problem on-hand before going to the user to fix the error. On this blog entry, I will share the code that I used to print or capture the screen.



First you must include the following namespaces.

using System.Drawing;
using System.Drawing.Imaging;

Now here's the code that performs the print screen or capture screenshot operation.

        private void button1_Click(object sender, EventArgs e)
        {
            Bitmap printscreen = new Bitmap(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);

            Graphics graphics = Graphics.FromImage(printscreen as Image);

            graphics.CopyFromScreen(0, 0, 0, 0, printscreen.Size);

            printscreen.Save(@"C:\fryan0911\printscreen.jpg", ImageFormat.Jpeg);
        }
