c# - 在 C# 中保存打印屏幕

Question

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:\Temp\printscreen.jpg", ImageFormat.Jpeg);

这是我的打印屏幕按钮代码。问题是我按了几次按钮，它只是覆盖了旧的图像文件 (printscreen.jpg)，它不会创建另一个新的图像文件，如 printscreen1.jpg。

试试这个。每次都会生成一个唯一的文件。

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:\Temp\printscreen"+Guid.NewGuid()+".jpg", ImageFormat.Jpeg);

或

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);
var date = DateTime.Now.ToString("MMddyyHmmss");
bitmap.Save(@"C:\Temp\printscreen"+date+".jpg", ImageFormat.Jpeg);
