C＃：如何采取屏幕

Question

的部分截图像

TakeScreenshot(new Rectangle(0,0,100,100), "output.jpg"); 

Answer 1

使用以下命令：

 Rectangle rect = new Rectangle(0, 0, 100, 100); 
     Bitmap bmp = new Bitmap(rect.Width, rect.Height, PixelFormat.Format32bppArgb); 
     Graphics g = Graphics.FromImage(bmp); 
     g.CopyFromScreen(rect.Left, rect.Top, 0, 0, bmp.Size, CopyPixelOperation.SourceCopy); 
     bmp.Save(fileName, ImageFormat.Jpeg); 

Answer 2

你检查Graphics.CopyFromScreen方法？

Answer 3

使用Graphics.CopyFromScreen方法。谷歌变成this tutorial。

Answer 4

这里是捕获屏幕的代码。将值更改为您需要的大小。

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

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

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

printscreen.Save(@"C:\printscreen.jpg", ImageFormat.Jpeg); 

或做方法，该方法将返回捕捉这样的形象：

Image CaptureScreen(int sourceX, int sourceY, int destX, int destY, 
      Size regionSize) 
{ 
    Bitmap bmp = new Bitmap(regionSize.Width, regionSize.Height); 
    Graphics g = Graphics.FromImage(bmp); 
    g.CopyFromScreen(sourceX, sourceY, destX, destY, regionSize); 
    return bmp; 
} 
...... 
// call 
Image image = CaptureScreen(sourceX, sourceY, destX, destY, regionSize); 
image.Save(@"C:\Somewhere\screen.jpg);
