Use C to get the path to the system's special folder

win7 cannot write files to c disk. At present, users can only write files to their own user folders, such as MyDocuments, folders. The directory method to get these folders by using c# is:

string path=System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
