我想创建一个 C# 基对象类，它代表下面的 Json 文档（这是一个调查表）。我可以轻松地完成前三三行，但我如何从"FormBody": { }病房开始做嵌套的。

我已经看到人们在哪里使用public IDictionary<string, object> FormBody {get; set;}. 我可以将它传递给 Json.Net 并让它为我填充对象类吗？或者还有其他方法吗？

[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。您可以为您的 JSon 中的每个复杂类型创建一个类（可以直接使用 Strings 和 String[]）。

如何序列化：

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 ();
