如何將這個複雜的json文檔表示爲C＃對象？

Question

我想創建一個代表下面的Json文檔（這是一個問卷形式）的C＃基礎對象類。我可以輕鬆完成前三個三行，但我怎麼做"FormBody": { }在病房的嵌套。

我已經看到傢伙在哪裏使用public IDictionary<string, object> FormBody {get; set;}。我可以將它傳遞給Json.Net並讓它爲我填充對象類嗎？或者還有其他方法嗎？

Answer 1

[DataContract] 
public sealed class MyJson 
{ 
    [DataMember(Name="FormTitle", IsRequired = true)] 
    public string FormTitle { get; set; } 

    ... 

    [DataMember(Name="FormBody", IsRequired = true)] 
    public FormBody fb { get; set; } 
} 

[DataContract] 
public sealed class FormBody 
{ 
    [DataMember(Name="image", IsRequired = true)] 
    public Image img { get; set; } 

    ... 
} 

等等等等。您可以爲JSon中的每個複雜類型創建一個類（字符串和字符串[]可直接使用）。

如何序列：

var jsonString = ... 

var json = new DataContractJsonSerializer (typeof(MyJson)); 
var stream = new MemoryStream (System.Text.Encoding.UTF8.GetBytes (jsonString)); 
var myObj = (MyJson)json.ReadObject (stream); 
stream.Close(); 

如何反序列化：

FileStream fileStream = System.IO.File.Create (filepath); 

MemoryStream stream = new MemoryStream(); 
DataContractJsonSerializer jsonSerializer = new DataContractJsonSerializer (typeof(MyJson)); 

jsonSerializer.WriteObject (stream, myObj); 
stream.Position = 0; 
StreamReader sr = new StreamReader (stream); 

string jsonString = sr.ReadToEnd();
