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 == )
                 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;

         }
     }
