效果

格式化前的字符串：
    
    {id=11,name="xxj",age=111,time=DateTime.Now};
    
    格式化后的字符串：
    {
      id=11,
      name="xxj",
      age=111,
      time='2010-1-1 1:1:1'
    };

需要1：Newtonsoft.Json.dll 组件

需要2：自定义扩展方法

/// <summary>
            /// 生成Json格式
            /// key=字段名，value=字段值
            /// </summary>
            /// <typeparam name="T">待序列化的对象</typeparam>
            /// <returns></returns>
            /// <remarks>创建人员(日期):★xxj★(111026 19:08)</remarks>
            public static string ToJsonSerialize<T>(this T obj) //where T : class
            {
                if (obj.IsNullOrDbNull())
                    return string.Empty;
    
                if (obj is DataTable)
                    return DataTableToJson(obj as DataTable);
    
                JavaScriptSerializer serialize = new JavaScriptSerializer();
                //针对日期序列化时区的转化
                var json = Regex.Replace(serialize.Serialize(obj), @"\\/Date\((-?\d+)\)\\/", match =>
                {
                    var dt = new DateTime(1970, 1, 1);
                    dt = dt.AddMilliseconds(long.Parse(match.Groups[1].Value));
                    dt = dt.ToLocalTime();
                    return dt.ToString("yyyy-MM-dd HH:mm:ss");
                });
                return json;
            }

格式化json代码

/// <summary>
        /// 测试json字符串格式化
        /// </summary>
        [TestMethod]
        public void TestJsonFormat()
        {
            //格式化json字符串
            var data = new
            {
                id=11,
                name="xxj",
                age=111,
                time=DateTime.Now
            };
            var json = data.ToJsonSerialize();
            //Newtonsoft.Json.dll, v4.5.0.0
            JsonSerializer serializer = new JsonSerializer();
            TextReader tr = new StringReader(json);
            JsonTextReader jtr = new JsonTextReader(tr);
            object obj = serializer.Deserialize(jtr);
            if (obj != null)
            {
                StringWriter textWriter = new StringWriter();
                JsonTextWriter jsonWriter = new JsonTextWriter(textWriter)
                {
                    Formatting = Formatting.Indented,
                    Indentation = 4,
                    IndentChar = ' '
                };
                serializer.Serialize(jsonWriter, obj);
                var jsonF = textWriter.ToString();
            }
    
    
            Assert.IsTrue(true);
        }
