在Silverlight中动态创建Enum时，多次调用改方法出现上图所示错误，后来发现定义名称都是一样的，

在程序中声明全局变量去区别就可以了。

int num = 1;

private Type CreateEnum(List<string> lists,string enumName)
        {
            AppDomain app = AppDomain.CurrentDomain;
            AssemblyName aName = new AssemblyName("SilverlightEnum" + num);

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

            ModuleBuilder mb = ab.DefineDynamicModule(aName.Name + "Module");

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

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

            num++;
            return eb.CreateType();

        }

Silverlight 用户代码未处理 TypeLoadException
