Zoho Crm API から返される次の複雑な JSON 結果を解析しようとしています。

{
"response":
{
    "result":
    {
        "Contacts":
        {
            "row":
            [
                {
                    "no":"1",
                    "FL":
                    [
                        {
                            "content":"555555000000123456",
                            "val":"CONTACTID"
                        },
                        {
                            "content":"555555000000012345",
                            "val":"SMOWNERID"
                        },
                        {
                            "content":"John Doe",
                            "val":"Contact Owner"
                        },
                        {
                            "content":"Pete",
                            "val":"First Name"
                        },
                        {
                            "content":"Smith",
                            "val":"Last Name"
                        },
                        {
                            "content":"pete@mail.com",
                            "val":"Email"
                        },
                        {
                            "content":"5555551000000012346",
                            "val":"SMCREATORID"
                        },
                        {
                            "content":"Jane Doe",
                            "val":"Created By"
                        },
                        {
                            "content":"555555000000012347",
                            "val":"MODIFIEDBY"
                        },
                        {
                            "content":"Doris Doe",
                            "val":"Modified By"
                        },
                        {
                            "content":"2013-06-14 17:24:10",
                            "val":"Created Time"
                        },
                        {
                            "content":"2013-06-14 17:24:10",
                            "val":"Modified Time"
                        },
                        {
                            "content":"2013-06-14 17:28:05",
                            "val":"Last Activity Time"
                        }
                    ]
                },
                {
                    ...
                }
            ]
        }
    },
    "uri":"/crm/private/json/Contacts/getRecords"
}

}

これが私のオブジェクトの外観です。

public class Contact
{
    [JsonProperty(PropertyName = "CONTACTID")]
    public string ContactID { get; set; }
    [JsonProperty(PropertyName = "SMOWNERID")]
    public string OwnerID { get; set; }
    [JsonProperty(PropertyName = "Contact Owner")]
    public string ContactOwner { get; set; }
    [JsonProperty(PropertyName = "First Name")]
    public string FirstName { get; set; }
    [JsonProperty(PropertyName = "Last Name")]
    public string LasName { get; set; }
    [JsonProperty(PropertyName = "Email")]
    public string Email { get; set; }
    [JsonProperty(PropertyName = "SMCREATORID")]
    public string CreatorID { get; set; }
    [JsonProperty(PropertyName = "Created By")]
    public string CreatedBy { get; set; }
    [JsonProperty(PropertyName = "MODIFIEDBY")]
    public string ModifiedByID { get; set; }
    [JsonProperty(PropertyName = "Modified By")]
    public string ModifiedBy { get; set; }
    [JsonProperty(PropertyName = "Created Time")]
    public DateTime CreatedTime { get; set; }
    [JsonProperty(PropertyName = "Modified Time")]
    public DateTime ModifiedTime { get; set; }
    [JsonProperty(PropertyName = "Last Activity Time")]
    public DateTime LastActivityTime { get; set; }
}

「行」パターンは繰り返されます（1、2、3 ... ではありません）ので、基本的に取得しようとしているのは、このタイプのオブジェクトの汎用リストです。JSON.NETを使用しようとしていますが、これが簡単になる場合は、他の提案を受け入れます。

この場合、これは明らかに機能しません。

var response = JsonConvert.DeserializeObject<Contact>(jsonString);

そして、これもしません:

var deserializedObjects = JsonConvert.DeserializeObject<List<Contact>>(jsonString);

JavaScriptSerializer を使用してこれを解析するためにまとめた回避策を次に示しますが、これはこれまでで最悪のコード ブロックの 1 つです。

            List<Contact> loContactList = new List<Contact>();
        Contact loContact = null;

        Dictionary<string, object> dictionary = new JavaScriptSerializer().Deserialize<Dictionary<string, object>>(jsonString);
        var response = (Dictionary<string, object>)dictionary["response"];
        var result = (Dictionary<string, object>)response["result"];
        var contacts = (Dictionary<string, object>)result["Contacts"];
        var row = (ArrayList)contacts["row"];

        foreach (var item in row)
        {
            var loArrayItem = (Dictionary<string, object>)item;
            var fl = (ArrayList)loArrayItem["FL"];

            loContact = new Contact();

            foreach (var contactitem in fl)
            {
                var contactdict = (Dictionary<string, object>)contactitem;
                string val = (string)contactdict["val"];
                string content = (string)contactdict["content"];

                if (val == "CONTACTID")
                {
                    loContact.ContactID = content;
                }
                else if (val == "SMOWNERID")
                {
                    loContact.OwnerID = content;
                }
                else if (val == "Contact Owner")
                {
                    loContact.ContactOwner = content;
                }
                else if (val == "First Name")
                {
                    loContact.FirstName = content;
                }
                else if (val == "Last Name")
                {
                    loContact.LastName = content;
                }
                else if (val == "Email")
                {
                    loContact.Email = content;
                }
                else if (val == "SMCREATORID")
                {
                    loContact.CreatorID = content;
                }
                else if (val == "Created By")
                {
                    loContact.CreatedBy = content;
                }
                else if (val == "MODIFIEDBY")
                {
                    loContact.ModifiedByID = content;
                }
                else if (val == "Modified By")
                {
                    loContact.ModifiedBy = content;
                }
                else if (val == "Created Time")
                {
                    loContact.CreatedTime = Convert.ToDateTime(content);
                }
                else if (val == "Modified Time")
                {
                    loContact.ModifiedTime = Convert.ToDateTime(content);
                }
                else if (val == "Last Activity Time")
                {
                    loContact.LastActivityTime = Convert.ToDateTime(content);
                }
            }

            loContactList.Add(loContact);
        }

私は StackOverflow に関する他の同様の投稿を調べましたが、この問題の解決策を提供しているようには見えません。誰かがこれに対する解決策を持っていますか? 私の目標は、この JSON 応答をより洗練された方法で解析することです。これには、100 万の辞書オブジェクトと ArrayList が必要ありません! どんな助けでも大歓迎です。

ありがとう、ピート

JSON.Net を使用して逆シリアル化するには、以下のクラスを使用します。

public class ResponseActual
{

    [JsonProperty("response")]
    public Response2 Response { get; set; }
}

public class Response2
{

    [JsonProperty("result")]
    public Result Result { get; set; }

    [JsonProperty("uri")]
    public string Uri { get; set; }
}

public class Result
{

    [JsonProperty("Contacts")]
    public Contacts Contacts { get; set; }
}

public class Contacts
{

    [JsonProperty("row")]
    public IList<Row> Row { get; set; }
}

  public class Row
{

    [JsonProperty("no")]
    public string No { get; set; }

    [JsonProperty("FL")]
    public IList<FL> FL { get; set; }
}

 public class FL
{

    [JsonProperty("content")]
    public string Content { get; set; }

    [JsonProperty("val")]
    public string Val { get; set; }
}

//To De-serialize
ResponseActual respone = JsonConvert.DeserializeObject<ResponseActual>(jSON_sTRING)

//Get the contacts list
List<FL> contacts = respone.Response.Result.Contacts.Row[0].FL.ToList();

//Now Get the required value using LINQ
var value = contacts.Where<FL>((s, e) => s.Val =="Email").Select(x=>x.Content).Single();

これをチェックアウトすることもでき ます-Newtonsoftを使用してJSONを.NETオブジェクトにデシリアライズします（またはLINQ to JSON多分？）

you can use this code:

    dynamic dictionary = (JsonConvert.DeserializeObject>(jsonstring))["response"];


            var result = dictionary.result;
            var contact= result.Contacts;
            var row= contact.row;

            foreach (var item in row)
            {

                var no= item.no;

            }

逆シリアル化オブジェクト Type に JSON の次の部分を含める必要があります。

{
"response":
{
    "result":
    {
        "Contacts":
        {
            "row":
            [
                {
                    "no":"1",
                    "FL":

クラス タイプ : 'Contact' は不適切です。
