如何使用Selenium C＃拍摄下拉菜单的屏幕截图？

Question

I am new to Selenium and to C#. I am trying to create an automation code to a website and saving screenshots of the elements of each step. Figured a way to save screenshots only of specified elements, however the drop-down menus are not appearing on the saved images. Tried using the PRTSC option which is doing the job but taking images only of the screen and I only need image of the drop-down menu and not the whole page. Is there a way in Selenium that I can take screenshot only of the drop-down list? Any idea or advice is welcome.

I was looking for the same, to have screenshots of dropdowns. I figured that, on using the keyboard strokes: Alt+Down arrow we can open the dropdown. The same can be done by below:

//Alt key code is 18, the below does the alt key stroke
selenium.KeyDownNative("18");

//Down arrow key code is 40, the below does the downkey stroke
selenium.KeyDownNative("40");

//Takes screenshot
selenium.CaptureScreenshot(@"d:\Image.jpg");

//Release alt key
selenium.KeyUpNative("18");

//Releases down arrow key.
selenium.KeyUpNative("40");
