无法反序列化JSON正确

Question

我有一个类

[DataContract] 
    public class restaurant 
    { 
     public restaurant() {} 

     public restaurant(string Address, string Description, int Id, float Latitude, float Longitude, string Name, 
      string OpeningHours, string Phone, string Sandwich, string Price, string UpdatedAt , string Website, float Score, int RatingCount, string ThumbnailUrl) 
     { 
      address = Address; 
      description = Description; 
      id = Id; 
      latitude = Latitude; 
      longitude = Longitude; 
      name = Name; 
      opening_hours = OpeningHours; 
      phone = Phone; 
      sandwich = Sandwich; 
      price = Price; 
      updated_at = UpdatedAt; 
      website = Website; 
      score = Score; 
      rating_count = RatingCount; 
      thumbnail_url = ThumbnailUrl; 

     } 


     [DataMember] 
     public string address { get; set; } 
     [DataMember] 
     public string description { get; set; } 
     [DataMember] 
     public int id { get; set; } 
     [DataMember] 
     public float latitude { get; set; } 
     [DataMember] 
     public float longitude { get; set; } 
     [DataMember] 
     public string name { get; set; } 
     [DataMember] 
     public string opening_hours { get; set; } 
     [DataMember] 
     public string phone { get; set; } 
     [DataMember] 
     public string sandwich { get; set; } 
     [DataMember] 
     public string price { get; set; } 
     [DataMember] 
     public string updated_at { get; set; } 
     [DataMember] 
     public string website { get; set; } 
     [DataMember] 
     public float score { get; set; } 
     [DataMember] 
     public int rating_count { get; set; } 
     [DataMember] 
     public string thumbnail_url { get; set; } 

    } 

和JSON字符串：

string json = @"{""restaurant"":{""address"":""blablabla"",""description"":""blablabla"",""id"":6,""latitude"":12.1,""longitude"":-12.3, 
            ""name"":""blablabla"",""opening_hours"":""Mon-Fri: 12pm-2:30pm\r\n     6:30pm-11pm \r\nSat: 12-3:30pm/6:30-11pm \r\nSun: 12-9pm"",""phone"":""123456"",""price"":""1"", ""sandwich"":""blablabla"",""updated_at"":""2011-10-10T21:40:17Z"", 
            ""website"":""blablabla"",""score"":4.3,""ratings_count"":3,""thumbnail_url"":""http://website.com/1.jpg""}}"; 

我想使用此代码反序列化：

restaurant LR; 

      using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json))) 
      { 
       DataContractJsonSerializer serializer = 
         new DataContractJsonSerializer(typeof(restaurant)); 

       LR= (restaurant)serializer.ReadObject(ms); 
      } 

但它不工作！奇怪的是，当我尝试反序列化它时，它不显示错误（所以json是好的，如果我故意拧上json，它会在运行时显示错误），但餐厅对象是空的。我究竟做错了什么？

根据您的餐厅类，我认为这是一个会被你的代码进行反序列化JSON的：

string json = @"{""address"":""blablabla"",""description"":""blablabla"",""id"":6,""latitude"":12.1,""longitude"":-12.3, 
           ""name"":""blablabla"",""opening_hours"":""Mon-Fri: 12pm-2:30pm\r\n     6:30pm-11pm \r\nSat: 12-3:30pm/6:30-11pm \r\nSun: 12-9pm"",""phone"":""123456"",""price"":""1"", ""sandwich"":""blablabla"",""updated_at"":""2011-10-10T21:40:17Z"", 
           ""website"":""blablabla"",""score"":4.3,""ratings_count"":3,""thumbnail_url"":""http://website.com/1.jpg""}"; 

我不能谈论的日期，但。有时他们抛出文化的原因。

编辑：为了让你的序列化JSON，你可以创建一个外部类休息。像，

public class rest 
{ 
    public restaurant restaurant { get; set; } 
} 

那么你的反序列化的代码也将需要更改为：

rest LR; 

using (MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json))) 
{ 
    DataContractJsonSerializer serializer = 
        new DataContractJsonSerializer(typeof(rest)); 

    LR = (rest)serializer.ReadObject(ms); 
} 

BIG注意 如果你能容纳像一些[餐饮] S

{"restaurant":[{""address"":"blah1", ...}, {""address"":"blah2", ...}]} 

，那么您可能需要将餐厅的成员休息类为阵列如下：

public class rest 
{ 
    public restaurant[] restaurant { get; set; } 
}
