主要用到的类：DataContractJsonSerializer，该类被申明在System.Runtime.Serialization.Json命名空间下，而System.Runtime.Serialization.Json命名空间是被放置在System.ServiceModel.Web.dll程序集里，因此我们要用到DataContractJsonSerializer类，首先应添加对System.ServiceModel.Web的引用，然后添加System.Runtime.Serialization.Json命名空间，注意DataContractJsonSerializer序列化的方式是采用数据契约序列化，因此我们可以通过DataMemberAttribute来控制那些被序列化，那些不被序列化。
例如，我们这里有一个类：
例如，我们这里有一个类：
1
[DataContract]
2 public class User
3 {
4 public User() { }
5 [DataMember]
6 public bool IsMember { get ; set ; }
7 [DataMember]
8 public string Name { get ; set ; }
9 public int Age { get ; set ; }
10 }
2 public class User
3 {
4 public User() { }
5 [DataMember]
6 public bool IsMember { get ; set ; }
7 [DataMember]
8 public string Name { get ; set ; }
9 public int Age { get ; set ; }
10 }
我们现在在一个ashx文件里创建一个实例并将其序列化：
public
class
JsonWriter : IHttpHandler
{
public void ProcessRequest (HttpContext context)
{
DataContractJsonSerializer serializer = new DataContractJsonSerializer( typeof (User));
User user = new User() { IsMember = true , Name = " Zhang Liang " , Age = 24 };
serializer.WriteObject(context.Response.OutputStream, user);
context.Response.ContentType = " text/plain " ;
}
public bool IsReusable {
get {
return false ;
}
}
}
{
public void ProcessRequest (HttpContext context)
{
DataContractJsonSerializer serializer = new DataContractJsonSerializer( typeof (User));
User user = new User() { IsMember = true , Name = " Zhang Liang " , Age = 24 };
serializer.WriteObject(context.Response.OutputStream, user);
context.Response.ContentType = " text/plain " ;
}
public bool IsReusable {
get {
return false ;
}
}
}
看输出结果：
{
"
IsMember
"
:
true
,
"
Name
"
:
"
Zhang Liang
"
}
反序列化：
public
class
JsonWriter : IHttpHandler
{
public void ProcessRequest (HttpContext context)
{
DataContractJsonSerializer serializer = new DataContractJsonSerializer( typeof (User));
User user = serializer.ReadObject(context.Request.InputStream) as User;
//
.使用User对象
context.Response.Write( " OK " );
context.Response.ContentType = " text/plain " ;
}
public bool IsReusable {
get {
return false ;
}
}
}
{
public void ProcessRequest (HttpContext context)
{
DataContractJsonSerializer serializer = new DataContractJsonSerializer( typeof (User));
User user = serializer.ReadObject(context.Request.InputStream) as User;
//
.使用User对象
context.Response.Write( " OK " );
context.Response.ContentType = " text/plain " ;
}
public bool IsReusable {
get {
return false ;
}
}
}
