C# 在windowsce上发射

我有以下获取和保存委托的方法，这些方法比每秒使用反射数千次时使用反射快得多：

private FastInvokeHandler GetMethodInvoker(MethodInfo methodInfo)
    {
        DynamicMethod dynamicMethod = new DynamicMethod(String.Empty,
                      typeof(Object), new Type[] { typeof(Object), 
                      typeof(Object[]) },
                      methodInfo.DeclaringType.Module);
        ILGenerator il = dynamicMethod.GetILGenerator();
        ParameterInfo[] ps = methodInfo.GetParameters();
        Type[] paramTypes = new Type[ps.Length];
        for (int i = 0; i < paramTypes.Length; i++)
        {
            if (ps[i].ParameterType.IsByRef)
                paramTypes[i] = ps[i].ParameterType.GetElementType();
            else
                paramTypes[i] = ps[i].ParameterType;
        }
        LocalBuilder[] locals = new LocalBuilder[paramTypes.Length];

        for (int i = 0; i < paramTypes.Length; i++)
        {
            locals[i] = il.DeclareLocal(paramTypes[i], true);
        }
        for (int i = 0; i < paramTypes.Length; i++)
        {
            il.Emit(OpCodes.Ldarg_1);

            il.Emit(OpCodes.Ldnull);
        else
            EmitBoxIfNeeded(il, methodInfo.ReturnType);

        }

        il.Emit(OpCodes.Ret);
        FastInvokeHandler invoder = (FastInvokeHandler)
           dynamicMethod.CreateDelegate(typeof(FastInvokeHandler));
        return invoder;
    }

    private static void EmitCastToReference(ILGenerator il, System.Type type)

        if (value > -129 && value < 128)

            il.Emit(OpCodes.Ldc_I4, value);
    }

    public Object TypeConvert(Object source, Type DestType)
    {
        Object NewObject = System.Convert.ChangeType(source, DestType);
        return (NewObject);
    }

在compact framework 3.5上有没有类似的方法？甚至可以使用本机C++？< /P>
