[c#] Saving image to file

I am working on a basic drawing application. I want the user to be able to save the contents of the image.

I thought I should use

System.Drawing.Drawing2D.GraphicsState img = drawRegion.CreateGraphics().Save();

but this does not help me for saving to file.

If you are drawing on the Graphics of the Control than you should do something draw on the Bitmap everything you are drawing on the canvas, but have in mind that Bitmap needs to be the exact size of the control you are drawing on:

  Bitmap bmp = new Bitmap(myControl.ClientRectangle.Width,myControl.ClientRectangle.Height);
  Graphics gBmp = Graphics.FromImage(bmp);
  gBmp.DrawEverything(); //this is your code for drawing
  gBmp.Dispose();
  bmp.Save("image.png", ImageFormat.Png);

Or you can use a DrawToBitmap method of the Control. Something like this:

Bitmap bmp = new Bitmap(myControl.ClientRectangle.Width, myControl.ClientRectangle.Height);
myControl.DrawToBitmap(bmp,new Rectangle(0,0,bmp.Width,bmp.Height));
bmp.Save("image.png", ImageFormat.Png);

You can try with this code

Image.Save("myfile.png", ImageFormat.Png)

You can save image , save the file in your current directory application and move the file to any directory .

 Bitmap btm = new Bitmap(image.width,image.height);
    Image img = btm;
                        img.Save(@"img_" + x + ".jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
                        FileInfo img__ = new FileInfo(@"img_" + x + ".jpg");
                        img__.MoveTo("myVideo\\img_" + x + ".jpg");
