Json.net dynamic serialization and processing of time formats, json.net serialization

About Json processing in my work

1. Dynamic serialization

Second: Time Format Processing

Generally, a class may have 10 to more attributes, but we only need to serialize three to five of them so that there will be extra data.

 

 

 

What if I only want to serialize id and name?

This is my online method:

Using Newtonsoft. json; using Newtonsoft. json. converters; using Newtonsoft. json. serialization; using System. collections. generic; using System. linq; namespace CYP. new. WCF. common. common {public class LimitPropsContractResolver: DefaultContractResolver {private string [] props = null; public LimitPropsContractResolver (string [] props) {this. props = props;} protected override IList <JsonProperty> CreateProperties (Type type, MemberSerialization memberSerialization) {IList <JsonProperty> list = base. createProperties (type, memberSerialization); // only the sorted return list listed in the list is retained. where (p => props. contains (p. propertyName )). toList ();}}}

Looking at the first figure of Json.net processing date format, we can see that Json.net processing date format. Nima is not a normal human can understand it.

 

You may find that Json.net contains something about the processing date.

 

 

 

However, at this time, you will find the Json.net reload

     public static string SerializeObject(object value);        public static string SerializeObject(object value, Formatting formatting);        public static string SerializeObject(object value, JsonSerializerSettings settings);        public static string SerializeObject(object value, params JsonConverter[] converters);        public static string SerializeObject(object value, Formatting formatting, JsonSerializerSettings settings);        public static string SerializeObject(object value, Formatting formatting, params JsonConverter[] converters);

You will find that the formats of dynamic serialization and time processing cannot coexist. This problem really makes my little headache .....

Solution:

using Newtonsoft.Json;using Newtonsoft.Json.Converters;using Newtonsoft.Json.Serialization;using System;using System.Collections.Generic;using System.Linq;namespace CYP.New.WCF.Common.Common{    public class LimitPropsContractResolver : DefaultContractResolver    {        private string[] props = null;        public LimitPropsContractResolver(string[] props)        {            this.props = props;        }        protected override IList<JsonProperty> CreateProperties(Type type, MemberSerialization memberSerialization)        {            IList<JsonProperty> list = base.CreateProperties(type, memberSerialization);            IsoDateTimeConverter iso = new IsoDateTimeConverter() { DateTimeFormat = "yyyy-MM-dd HH:mm:ss" };            IList<JsonProperty> listWithConver = new List<JsonProperty>();            foreach (var item in list)            {                if (props.Contains(item.PropertyName))                {                    if (item.PropertyType.ToString().Contains("System.DateTime"))                    {                        item.Converter = iso;                    }                    listWithConver.Add(item);                }            }            return listWithConver;        }    }}

What is JSON serialization? I learned json under net. What is serialization? What is the role?

The json string itself is organized in a certain format, just like the tag pairs used in xml, json needs to use:
"Key": "value"; format to organize;
In this way, it becomes a string sequence. The advantage of serialization is that Parsing is convenient and easy to understand. For example, javascript can directly convert json into an object using eval to call the value Attribute using the key;
I believe. net also has functions or classes for processing json strings. You can find them.

When JSONNET serializes an object as a JSON string, it can be specified. An attribute is not converted.

Mark the property under serialization:
[JsonProperty (Name = "password")]
Public string Password {get; set ;}

You can try it out without marking it ~
