如何將Json中的自定義節點反序列化為名稱不斷變化的c#?

[英]How do I deserialize a custom node in Json to c#, whose name keeps changing?

以下是我從端點收到的json部分。

如果您查看下面的Json,“用戶定義的網絡名稱”是一個自定義節點,並且名稱每次都會更改。

如何為此Json定義C#對象?

"addresses": {
            "public": [{
                "version": 6,
                "address": "2005:4600:788e:0910:1a72:81c0:ff03:c7y6"
            },
            {
                "version": 4,
                "address": "197.68.xx.xxx"
            }],
            "private": [{
                "version": 4,
                "address": "10.xx.xx.xxx"
            }],
            "User-Defined-Network-Name": [{
                "version": 4,
                "address": "192.xxx.x.xxx"
            }]
        }

這就是我走了多遠-

[Serializable]
    public class Addresses
    {
        public List<Public> @public { get; set; }
        public List<Private> @private { get; set; }
    }

我正在使用'JavascriptSerializer'類反序列化json。

謝謝,瑞安

可以將addresses反序列化為Dictionary<string,List<YourClass>>類的類型Dictionary<string,List<YourClass>>其中YourClass保存versionaddresss

var obj = new JavaScriptSerializer().Deserialize<Root>(jsonstring);

-

public class Root
{
    public Dictionary<string,List<VersionAddress>> addresses;
    //Your other fields/properties
}

public class VersionAddress
{
    public string version;
    public string address;
}

您可以利用C#的動態特性:

// this could come from user input:
string userDefinedName = "User-Defined-Network-Name";

string json =“您的JSON即將出現”;

var serializer = new JavaScriptSerializer();
dynamic result = serializer.DeserializeObject(json);
int version = result["addresses"][userDefinedName][0]["version"];
string address = result["addresses"][userDefinedName][0]["address"];

Console.WriteLine(version);
Console.WriteLine(address);

如果您想遍歷結果:

foreach (dynamic item in result["addresses"][userDefinedName])
{
    int version = item["version"];
    string address = item["address"];

    Console.WriteLine(version);
    Console.WriteLine(address);
}

為什么不使用網絡名稱關鍵字將網絡名稱設為字典? 然后,您可以對其進行迭代。

我不建議使用JavaScriptSerializer ,因為它已被棄用。 如果您需要第三方解決方案,那么據我JSON.NetJSON.Net相當不錯。

但是,我對依賴項很奇怪,因此如果不存在依賴項,我通常會自己滾動。 幸運的是,由於System.Runtime.Serialization命名空間中的DataContractJsonSerializer ,這System.Runtime.Serialization不太難。

您需要做的就是首先以嵌套方式定義所有對象:

using System.Reflection;
using System.Runtime.Serialization;      // You will have to add a reference
using System.Runtime.Serialization.Json; // to System.Runtime.Serialization.dll

[DataContract]
public class AddressInfo
{ 
  [DataMember(Name = "address")]
  public string Address { get; set; }

  [DataMember(Name = "version")]
  public int Version { get; set; }
}

[DataContract]
public class AddressList
{ 
  [DataMember(Name = "public")]
  public IEnumerable<AddressInfo> Public { get; set; }

  [DataMember(Name = "private")]
  public IEnumerable<AddressInfo> Private { get; set; }

  [DataMember(Name = "User-Defined-Network-Name")]
  public IEnumerable<AddressInfo> UserDefined { get; set; }
}

然后使用幾種輔助方法進行反序列化:

// This will change the DataMember.Name at runtime!
// This will only work if you know the node name in advance.
static void SetUserDefinedNodeName(string userDefinedNodeName)
{
  var type = typeof(AddressList);
  var property = type.GetProperty("UserDefined", BindingFlags.Default);
  var attribute = property.GetCustomAttribute<DataMemberAttribute>();

  if (attribute != null)
    attribute.Name = userDefinedNodeName;
}

static T Deserialize<T>(string jsonText, string userDefinedNodeName)
{
  SetUserDefinedNodeName(userDefinedName);

  var jsonBytes = Encoding.UTF8.GetBytes(jsonText);

  using (var stream = new MemoryStream(jsonBytes))
  {
    var serializer = new DataContractJsonSerializer(typeof(T));  
    var obj = serializer.ReadObject(stream) as T;

    return obj;
  }
}

然后像這樣使用它:

var jsonText = // get your json text somehow
var addressList = Deserialize<AddressList>(jsonText);
