比如xcode就可以在项目的目录树中看到resource文件夹。
vs2012中怎么看不到?但是看HelloWorld示例工程确实用了resource文件夹中的图片。
请问一下vs2012在哪里设置了resource的引用目录,还是有别的其他方法?

自己找到了。。。。
貌似Resources文件夹不能在项目的目录树中显示出来,要添加,修改,删除资源文件只能去Resource文件夹下操作。
In the project’s properties under Configuration Properties->Debugging you will see the executable’s working directory is set to something like $(ProjectDir)..This is how VS knows where it is… Everything in Resources is thus accessed as if it was in the same folder as the exe.
It is a common gotcha when running the exe outside VS not to copy the contents of your Resource folder to the folder containing the exe and then puzzling why no assets will load.
