反序列化

Question

我想deserealize JSON字符串是如下的值

{"data":[ 
{"description":"xxxxxx","created_time":1330356685}, 
    {"description":"zzzz","created_time":1329817903} 
]} 

我班如下：

public class NewFriends 
{ 
    public Data[] data { get; set; } 

    public class Data 
    { 
     string description { get; set; } 
     int created_time { get; set; } 
    } 
} 

，但是當我deserealizing值我在nFrnds

NewFriends nFrnds = serializer.Deserialize<NewFriends>(newFriends); 

的數組索引獲得空值請幫幫忙！

Answer 1

此代碼工作正常，我：

string s = "{\"data\":[{\"description\":\"xxxxxx\",\"created_time\":1330356685}, {\"description\":\"zzzz\",\"created_time\":1329817903}]}"; 
JavaScriptSerializer jss = new JavaScriptSerializer(); 
NewFriends nFrnds = jss.Deserialize(s, typeof(NewFriends)) as NewFriends; 
MessageBox.Show(nFrnds.data.Length.ToString()); 

Answer 2

我想建議你看看使用Json.Net。它將使反序列化過程變得輕而易舉。

PM>安裝，包裝Newtonsoft.Json

public class NewFriends 
{ 
    public List<Data> data { get; set; } 

} 

public class Data 
{ 
    string description { get; set; } 
    int created_time { get; set; } 
} 

var jsonObj = @"{"data":[ 
{"description":"xxxxxx","created_time":1330356685}, 
    {"description":"zzzz","created_time":1329817903} 
]}" 


NewFriends newFriends = JsonConvert.DeserializeObject<NewFriends>(jsonObj); 

Answer 3

嘗試使用List，而不是一個Array

public class NewFriends 
{ 
    public List<Data> data { get; set; } 

} 

public class Data 
{ 
    string description { get; set; } 
    int created_time { get; set; } 
}
