Json.Net 小提示1 (反序列化失败的解决方案)

最近在Unity中使用时遇到的问题,继承IEnumable接口导致反序列化失败,经过多方查找解决了.
下图调用 JsonConvert.PopulateObject();一直报错,反复对照json文件,并没有发现什么问题.

解决方案如下(我这里是使用默认解析比较方便,当然自定义解析也可以解决.),更详细的问题根源,继续往下.

下方代码是json.net,反序列化构造对象的过程.(可以看到JsonObject转换顺序在上方,高于IEnumerable).

        {
            Type t = ReflectionUtils.EnsureNotByRefType(objectType);

            if (IsJsonPrimitiveType(t))
            {

            JsonContainerAttribute? containerAttribute = JsonTypeReflector.GetCachedAttribute(t);

            if (containerAttribute is JsonObjectAttribute)
            {
                return CreateObjectContract(objectType);
            }

            if (containerAttribute is JsonArrayAttribute)

            }

            if (containerAttribute is JsonDictionaryAttribute)
            {
                return CreateDictionaryContract(objectType);
            }

            if (t == typeof(JToken) || t.IsSubclassOf(typeof(JToken)))
            {
                return CreateLinqContract(objectType);
            }

            if (CollectionUtils.IsDictionaryType(t))
            {
                return CreateDictionaryContract(objectType);
            }

            if (typeof(IEnumerable).IsAssignableFrom(t))
            {
                return CreateArrayContract(objectType);
            }

            if (CanConvertToString(t))
            {
                return CreateStringContract(objectType);
            }

#if HAVE_BINARY_SERIALIZATION
            if (!IgnoreSerializableInterface && typeof(ISerializable).IsAssignableFrom(t) && JsonTypeReflector.IsSerializable(t))
            {
                return CreateISerializableContract(objectType);
            }
#endif

#if HAVE_DYNAMIC
            if (typeof(IDynamicMetaObjectProvider).IsAssignableFrom(t))
            {
                return CreateDynamicContract(objectType);
            }
#endif

#if HAVE_ICONVERTIBLE
            // tested last because it is not possible to automatically deserialize custom IConvertible types
            if (IsIConvertible(t))
            {
                return CreatePrimitiveContract(t);
            }
#endif

            return CreateObjectContract(objectType);
        }

结语:好了反序列化也解决了,如果出现反序列化失败了,可以回头看看构造的顺序.
