在
Java中,我们可以这样做：
import java.awt.Dimension;
import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
import javax.imageio.ImageIO;
import java.io.File;
...
public void captureScreen(String fileName) throws Exception {
Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
Rectangle screenRectangle = new Rectangle(screenSize);
Robot robot = new Robot();
BufferedImage image = robot.createScreenCapture(screenRectangle);
ImageIO.write(image,"png",new File(fileName));
}
...
我们如何通过Web应用程序在.NET中执行此操作？捕获客户端的屏幕并将其从应用程序内部发送到服务器.
解决方法
.NET图形对象有一个名为CopyFromScreen()的方法,它将捕获屏幕的矩形区域并将其复制到位图中.最好的方法类似于以下内容：
public void CaptureImage(Point SourcePoint,Point DestinationPoint,Rectangle Selection,string FilePath)
{
using (Bitmap bitmap = new Bitmap(Selection.Width,Selection.Height)) {
using (Graphics g = Graphics.FromImage(bitmap)) {
g.CopyFromScreen(SourcePoint,DestinationPoint,Selection.Size);
}
bitmap.Save(FilePath,ImageFormat.Bmp);
}
}
