C# Folder Creation and search

I require a file-management function for an existing ASP.NET Website, written in C#, for folder creation and retrieval. The function: public static string CreateRetrieveFolder(string ProjectName, int ProjectID, string Location, string TemplateFolderPath) should create a file-folder in the passed in location (parent folder path) and return the Folderpath. Also it should copy the full content of TemplateFolderPath into the new created folder. The folder-name should be like "[435]-My Project Name" where 435 is the ProjectID. If the Project-Name contains characters, not allowed in the file system, the function should adjust the Folder name -> E.g. remove all non alphanumerical characters. If a folder already exists in the location with the same ProjectId, but a different name, the function should not create a folder (nor copy templatefolder), but return the path of the existing folder. (Project-Names can change, but ID remains the same). Since in this project only time-constraint and working functionality is important, this will decide who gets the work. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
