Manage User Properties

In many of my SharePoint projects I need to add some information about the logged user.
The User Profile Services is able to do that, I show you how step by step:

1. Go to Sharepoint Central Administrator and go to Manage service applications and click on User Profile Services
   
2. Then click on Manage User Properties
   
3. Create New Property and insert the information that you need
   
4. Now come back and click on Manage User Profiles
   
5. Find the user where you want insert the new property and edit it
   
6. Add the value that you need
   

Off course you can get the value programmatically:

//Get Current Site
var site = SPContext.Current.Site; 
//Define Server Context
var cx =  SPServiceContext.GetContext(site);
//Create an instance of the User Profile Manager
var profileManager = new UserProfileManager(cx); 
var user = profileManager.GetUserProfile(SPContext.Current.Web.CurrentUser.Name); 


string str = user["CustomerClassification"].Value.ToString();
