Silverlight 动态创建Enum

private Type CreateEnum()
        {

           List<string> lists = new List<string>();
            lists.Add("男");
            lists.Add("女");

            AppDomain app = AppDomain.CurrentDomain;
            AssemblyName aName = new    AssemblyName("EnumAssemble");

            AssemblyBuilder ab = app.DefineDynamicAssembly(aName, AssemblyBuilderAccess.Run);

            ModuleBuilder mb = ab.DefineDynamicModule("EnumModule");

            EnumBuilder eb = mb.DefineEnum("Sexs", TypeAttributes.Public, typeof(System.Int32));

            for (int i = 0; i < lists.Count; i++)
            {
                eb.DefineLiteral(lists[i], i);
            }
            return eb.CreateType();
        }
