C#实现JSON序列化与反序列化

Posted 2020-08-25 wuln

1、使用 javascriptSerializer类实现序列化

namespace: System.Web.Script.Serialization

eg:

 1 // 序列化
 2 private string ObjectToJson(Person obj)
 3 {
 4     JavaScriptSerializer jsonSerialize = new JavaScriptSerializer();
 5     return jsonSerialize.Serialize(obj);
 6 }
 7 // 反序列化
 8 private Person JsonToObject(string jsonStr)
 9 {
10     JavaScriptSerializer jsonSerialize = new JavaScriptSerializer();
11     return jsonSerialize.Deserialize<Person>(jsonStr);
12 }

注：可用 [ScriptIgnore] 标记不序列化的属性

2、使用 DataContractJsonSerializer类实现序列化

namespace:System.Runtime.Serialization.Json

eg:

 1 // 序列化
 2 using (MemoryStream stream =new MemoryStream())
 3 {
 4     DataContractJsonSerializer jsonSerialize =new DataContractJsonSerializer(Person);
 5     jsonSerialize.WriteObject(stream, obj);
 6     jsonStr = Encoding.UTF8.GetString(stream.ToArray());
 7 }
 8 // 反序列化
 9 using (MemoryStream stream =new MemoryStream(Encoding.UTF8.GetBytes(jsonStr)))
10 {
11     DataContractJsonSerializer jsonSerialize =new DataContractJsonSerializer(Person);
12     obj = (Person)jsonSerialize.ReadObject(stream);
13 }

注：可用 [IgnoreDataMember] 标记不序列化的属性
