JSON字符串和Dictionary字典类型的相互转换

在开发过程中，往往会遇到数据类型转换的情况，根据自己的业务，可能转换类型有多种，下面就说一下json字符串和字典类型的转换。

public static class JsonUntity
    {
        /// <summary>
        /// 将字典类型序列化为json字符串
        /// </summary>
        /// <typeparam name="TKey">字典key</typeparam>
        /// <typeparam name="TValue">字典value</typeparam>
        /// <param name="dict">要序列化的字典数据</param>
        /// <returns>json字符串</returns>
        public static string SerializeDictionaryToJsonString<TKey, TValue>(Dictionary<TKey, TValue> dict)
        {
            if (dict.Count == 0)
                return "";

            string jsonStr = JsonConvert.SerializeObject(dict);
            return jsonStr;
        }

        /// <summary>
        /// 将json字符串反序列化为字典类型
        /// </summary>
        /// <typeparam name="TKey">字典key</typeparam>
        /// <typeparam name="TValue">字典value</typeparam>
        /// <param name="jsonStr">json字符串</param>
        /// <returns>字典数据</returns>
        public static Dictionary<TKey, TValue> DeserializeStringToDictionary<TKey, TValue>(string jsonStr)
        {
            if (string.IsNullOrEmpty(jsonStr))
                return new Dictionary<TKey, TValue>();

            Dictionary<TKey, TValue> jsonDict = JsonConvert.DeserializeObject<Dictionary<TKey, TValue>>(jsonStr);

            return jsonDict;

        }
    }
