Remarks
ASP.NET uses the ProfileBase class to create the class used for the user profile. When an application that has the user profile enabled is started, ASP.NET creates a new class of type ProfileCommon, which inherits from the ProfileBase class. Strongly typed accessors are added to the ProfileCommon class for each property defined in the profile configuration section. The strongly typed accessors of the ProfileCommon class call the SetPropertyValue method to pass property values to the ProfileProvider to be stored at the data source.
You can use the SetPropertyValue method to assign property values in the user profile for your application by name. Values are untyped, and type checking will be done at run time, not compile time. For strongly typed access to profile property values, you can access the property by name as a member of the Profile property that is available on each page, for example, Profile.CustomerAddress.
