C# Take ScreenShot of .net control within application and attach to Outlook Email [duplicate]

Question

Does anyone know how to take a screenshot using C# and limit it to take a picture of a specific container/portion of an application. I do not want the whole screen or whole window of the application.

My Panel is simply called: panel1 User would click a "button" and take screenshot of panel1 and attach to email.

I would like to take a screen shot of that section only and then save locally to the C:\ Drive and/or attach or embed into an outlook email.

I read other various things on the internet but most of them had to deal with creating complex changes in take a screenshot of a web browser control which I am not looking for.

Answer 1

If you just want to the Panel's screenshot, you can use the built-in DrawToBitmap method.

Bitmap bmp = new Bitmap(myPanel.Width, myPanel.Height);
myPanel.DrawToBitmap(bmp, new Rectangle(0, 0, bmp.Width, bmp.Height));
bmp.Save(@"C:\MyPanelImage.bmp");

Just note that some controls may not work with this functionality such as the WebBrowser and RichTextBox controls but it should work for most other controls (textbox, labels etc..)

Answer 2

I do this using something like

public static void TakeCroppedScreenShot(
    string fileName, int x, int y, int width, int height, ImageFormat format)
{
    Rectangle r = new Rectangle(x, y, width, height);
    Bitmap bmp = new Bitmap(r.Width, r.Height, PixelFormat.Format32bppArgb);
    Graphics g = Graphics.FromImage(bmp);
    g.CopyFromScreen(r.Left, r.Top, 0, 0, bmp.Size, CopyPixelOperation.SourceCopy);
    bmp.Save(fileName, format);
}

I hope this helps
