C# Json序列化与反序列化

http://blog.csdn.net/chenbin520/article/details/8711142

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);
