According to the documentation the return value is the number of objects updated in the context:

Return Value
Type: System.Int32
The number of objects written to the underlying database.

So your method could look like this:

int returnValue = CS.SaveChanges();
return returnValue > 0 ? 
    String.Format("{0} User profiles have been updated successfully.", returnvalue) : 
    "No updates have been written to the database.";

context.SaveChanges return 0 when updated without any change
