Is there a way to retain this value without having some private variable in my

问题 I have been writing a cms with MVC being used as the main engine for generating the pages. I am going well, but wanted the ability to create a unique razor template per site and possibly per view if I need to. My rules are that each project has to have a unique code which is linked with a url. Assets for each project site are stored in a way that the location relates to the project. So an assets associated with project C0001 would be stored in assets\C0001\ and for C0002: assets\C0002\ and so
