Searching for a default "check mark" icon

I am currently searching for an icon that shows a green check mark, such as this:

Basically what I want to do is the following: My C# WPF application contains a ListView with some entries and each of the entry gets validated. Depending on the outcome of the validation, such a green check mark or a red cross should be displayed.

I found a very nice red cross in the class SystemIcons. It is called SystemIcons.Error. The SystemIcons class also provides other icons like "开发者_开发问答Exclamation", "hand", "Shield", "Question" and various other icons, however there is no such a check mark thing.

Does anyone know whether such a check mark icon exists in some default library? I googled but I could not find anything alike. In case there is no such Icon, I would have to take some image from the web (like I posted here), but that would be the last option since my application should look consistent and I'm pretty sure Microsoft uses lots of those green things in many places of Windows. So there must be some icon I could use, right?

Best wishes, Christian

If you're using one of the full versions of Visual Studio, you could always check out the Visual Studio Image Library that comes with Visual Studio.

I'm double checking now to make sure it contains something like what you're looking for.

What size icon images do you need?

If 16x16 will do then I'd recommend the silk icon set at famfamfam.com. This set is nice and consistent, and contains a green check mark.
