Sql Server CLR Functions

While writing a CLR function Sql Server can we use namespaces ?

namespace SomeName1.SomeName2
{
   public static class SomeClass
   {
       [SqlFunction]
       public static SqlString SomeMethod(SqlString input)
       {
          // ....
       }
   }
}

If so, then how do we call this function from SqlServer. In other words how do we call CLR functions from SQL Server with namespaces?
