-------- DRAFT解决方案-----------

  VAR topLeftCorner = MainBrowser.PointToScreen（新System.Windows.Point（0，0））;
VAR topLeftGdiPoint =新System.Drawing.Point（（INT）topLeftCorner.X，（INT）topLeftCorner.Y）;
VAR大小=新System.Drawing.Size（（INT）MainBrowser.ActualWidth，（INT）MainBrowser.ActualHeight）;

位图的截图=新位图（（INT）MainBrowser.ActualWidth，（INT）MainBrowser.ActualHeight）;

使用（VAR图形= Graphics.FromImage（截图））
{
   graphics.CopyFromScreen（topLeftGdiPoint，新System.Drawing.Point（）
        大小，CopyPixelOperation.SourceCopy）;
}

screenShot.Save（@D：\ TEMP \ screenshot.png）;
 

解决方案

作为一种理念，你可以使用安装在PC上的虚拟打印机和打印的图像。

  PrintDialog类P =新PrintDialog类（）;
p.PrintVisu​​al（webBrowser1webBrowser1）;
 

I need to get a screenshot of the page which downloads WPF Webrowser Control on fly in memory.

The basic requirement is the WPF Webrowser is hidden or even doesn't implemented in XAML.

Is it possible to do? If yes then how?

-------- DRAFT SOLUTION -----------

var topLeftCorner = MainBrowser.PointToScreen(new System.Windows.Point(0, 0));
var topLeftGdiPoint = new System.Drawing.Point((int)topLeftCorner.X, (int)topLeftCorner.Y);
var size = new System.Drawing.Size((int)MainBrowser.ActualWidth, (int)MainBrowser.ActualHeight);

Bitmap screenShot = new Bitmap((int)MainBrowser.ActualWidth, (int)MainBrowser.ActualHeight);

using (var graphics = Graphics.FromImage(screenShot))
{
   graphics.CopyFromScreen(topLeftGdiPoint, new System.Drawing.Point(),
        size, CopyPixelOperation.SourceCopy);
}

screenShot.Save(@"D:\Temp\screenshot.png");

解决方案

As an idea you can use a virtual printer installed on your PC and print as image.

PrintDialog p = new PrintDialog();
p.PrintVisual(webBrowser1,"webBrowser1");
