初探Newtonsoft.json

Json的序列化和反序列化是个使用面很广的东西；

原因就在于当你开始使用webapi进行数据交互的时候，很多的操作就需要依靠反序列化将传递的json数据解析即可；

下载方式可以用管理NuGet包进行下载，注意这里需要配置NuGet的包地址：

 

 注意源地址为：https://www.nuget.org/api/v2/

示例代码如下：

客户端：

 1 string apiUrl = "http://localhost:3120/";
 2 HttpWebRequest req = (HttpWebRequest)WebRequest.Create(apiUrl+ @"api/Student");
 3 req.Method = "GET";
 4 //req.ContentType = "application/json";
 5 
 6 HttpWebResponse res = (HttpWebResponse)req.GetResponse();
 7 Stream resStream = res.GetResponseStream();
 8 StreamReader strReader = new StreamReader(resStream, Encoding.UTF8);
 9 string data = strReader.ReadToEnd();
10 List<Student> listData = JsonConvert.DeserializeObject<List<Student>>(data);//反序列化

服务端API：

 1   public class StudentController : ApiController
 2     {
 3         public List<Student> GetStudentsInfo()
 4         {
 5             Student s1 = new Student() { ID = 1, Name = "Lee", Age = 12 };
 6             Student s2 = new Student() { ID = 2, Name = "Tom", Age = 22 };
 7             Student s3 = new Student() { ID = 3, Name = "Han", Age = 34 };
 8             Student s4 = new Student() { ID = 4, Name = "Keven", Age = 14 };
 9             Student s5 = new Student() { ID = 5, Name = "Loce", Age = 43 };
10             Student s6 = new Student() { ID = 6, Name = "KAka", Age = 54 };
11             List<Student> res = new List<Student>() { s1, s2, s3, s4, s5,s6 };
12             return res;
13         }      
14     }
