在C＃中使用嵌套数组反序列化JSON

Question

我在这里尝试反序列化这个JSON时遇到了麻烦：

{
    "response": {
        "numfound": 1,
        "start": 0,
        "docs": [
            {
                "enID": "9999",
                "startDate": "2013-09-25",
                "bName": "XXX",
                "pName": "YYY",
                "UName": [
                    "ZZZ"
                ],
                "agent": [
                    "BobVilla"
                ]
            }
        ]
    }
}

我为此创建的类是：

public class ResponseRoot {
    public Response response;
}

public class Response {
    public int numfound { get; set; }
    public int start { get; set; }
    public Docs[] docs;
}

public class Docs {
    public string enID { get; set; }
    public string startDate { get; set; }
    public string bName { get; set; }
    public string pName { get; set; }
    public UName[] UName;
    public Agent[] agent;
}

public class UName {
    public string uText { get; set; }
}

public class Agent {
    public string aText { get; set; }
}

但是，每当我打电话：

    ResponseRoot jsonResponse = sr.Deserialize<ResponseRoot>(jsonString);

jsonResponse最终为null，JSON没有反序列化。 我似乎无法说出为什么我的类可能对这个JSON有误。

Answer 1

你的代码表明Docs的UName属性是一个对象数组，但它是json中的一个字符串数组，同样适用于agent

试试这个：

 public class Docs
 {
   public string enID { get; set; }
   public string startDate { get; set; }
   public string bName { get; set; }
   public string pName { get; set; }
   public string[]  UName;
   public string[] agent;
 }

并删除UName和Agent类

Answer 2

这应该适用于您的类，使用json2csharp

public class Doc
{
    public string enID { get; set; }
    public string startDate { get; set; }
    public string bName { get; set; }
    public string pName { get; set; }
    public List<string> UName { get; set; }
    public List<string> agent { get; set; }
}

public class Response
{
    public int numfound { get; set; }
    public int start { get; set; }
    public List<Doc> docs { get; set; }
}

public class ResponseRoot
{
    public Response response { get; set; }
}
