捕获WPF窗口的屏幕截图的源示例 [英] Source example for capturing a screen capture of a WPF Window

问题描述

当前，我正在使用White API来控制WPF应用程序，但是White API没有功能来为其生成UI事件的当前窗口生成位图图像.因此，我正在寻找一些示例代码，可以在其中捕获在单独的进程(正在测试的应用程序)中运行的外部WPF窗口的快照，并传入UIAutomationClient.AutomationElement.到目前为止，我仅设法找到了GDI屏幕捕获应用程序的屏幕捕获源示例，在这些示例中，它们无法捕获正在运行的WPF应用程序的图像.任何关于在哪里看的建议都将不胜感激.

Currently I am using the White API to control a WPF application, but the White API has no functionality to generate a bitmap image of the current window for which it is generating UI events for. So, I am looking for some example code where I can take a snapshot of an external WPF window running in a separate process (application under test) passing in an UIAutomationClient.AutomationElement. So far, I have only managed to find screen capture source examples for GDI screen capture applications where they will not capture the image of a running WPF application. Any suggestions on where to look is greatly appreciated.

我在google上发现了这个问题:

在使用该示例之前，我将检查pInvoke以获得互操作调用的正确签名，因为我几乎可以肯定，您在提供的链接上看到的内容在64位系统上不起作用. pInvoke具有正确的方法原型.

I found this on google:

Before using that example, I would check pInvoke for the correct signatures of the interop calls because I''m almost positive that what you see at the link provided won''t work on a 64-bit system. pInvoke has the right method prototypes.
