每次都保存为新名称

Question

我可以在计时器上保存屏幕截图,但是我怎么能将它保存为新名称而不是每次都覆盖？

Bitmap bitmap = new Bitmap(Screen.PrimaryScreen.Bounds.Width,
                           Screen.PrimaryScreen.Bounds.Height);

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

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

bitmap.Save(@"c:tempscreenshot.bmp", ImageFormat.Bmp);

Answer 1

您可以使用方便的方法: Path.GetRandomFileName()

Bitmap bitmap = new Bitmap(Screen.PrimaryScreen.Bounds.Width, 
              Screen.PrimaryScreen.Bounds.Height);

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

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

bitmap.Save("c://" + Path.GetRandomFileName() + ".bmp", ImageFormat.Bmp);
