C# 利用Newtonsoft.Json进行Json序列化与反序列化

我们可以通过DataContractJsonSerializer类来序列化一个对象为json字符串。

public class JsonConvert<T>{public static string ObjectToJson(T obj){var serializer = new DataContractJsonSerializer(typeof(T));var stream = new MemoryStream();serializer.WriteObject(stream, obj);byte[] dataBytes = new byte[stream.Length];stream.Position = 0;stream.Read(dataBytes, 0, (int)stream.Length);string json = Encoding.UTF8.GetString(dataBytes);return json;}public static T JsonToObject(string jsonString){DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(T));var stream = new MemoryStream(Encoding.UTF8.GetBytes(jsonString));T t1 = (T)serializer.ReadObject(string);return t1;}}

使用Json.NET(Newtonsoft.Json)进行序列化与反序列化。

List<Student> students = studentBLL.GetALL();            string jsonStudents = JsonConvert.SerializeObject(students);

 string jsonStudents = service.GetAllStudent();            List<Student> students = JsonConvert.DeserializeObject<List<Student>>(jsonStudents);
