How to capture screen shot in .Net Core console application? RRS feed

  • Nope.  .NET Core cannot assume that there is such a thing as a "screen".

    You may be able to find third-party libraries for this, if you are running on a desktop.

  • Hi Akshay S. Deshmukh,

    Based on my test, the way I found which used to capture screen always use Bitmap. BitMap could not use in .Net Core. If it is possible, please use .Net.

    Here are two examples in .Net.

    Best Regards,

  • This is now possible using System.Drawing.Common

    var captureBmp = new Bitmap(1920, 1024, PixelFormat.Format32bppArgb);
    using (var captureGraphic = Graphics.FromImage(captureBmp))
        captureGraphic.CopyFromScreen(0, 0, 0, 0, captureBmp.Size);
        captureBmp.Save("capture.jpg", ImageFormat.Jpeg);

    It does require you to know the size of the screen as there no support for Screen.

    I've only tested this on Windows, but it should work on Linux too.

    He's a link to Scott Hanselman's blog using the library for image resizing.
