如何在运行时将方法附加到动态创建的C#类型？

TypeBuilder typeBuilder = moduleBuilder.DefineType("DynamicType", TypeAttributes.Public);

MethodBuilder methodBuilder = typeBuilder.DefineMethod("DynamicMethod", MethodAttributes.Public);

ILGenerator ilGenerator = methodBuilder.GetILGenerator();
ilGenerator.Emit(OpCodes.Ldstr, "Hello, world!");
ilGenerator.Emit(OpCodes.Call, typeof(Console).GetMethod("WriteLine", new Type[] { typeof(string) }));
ilGenerator.Emit(OpCodes.Ret);

typeBuilder.CreateType().GetMethod("DynamicMethod").Invoke(null, null);
