這篇文章主要介紹了C# Newtonsoft.Json 的使用說明，具有很好的參考價(jià)值，希望對大家有所幫助。一起跟隨小編過來看看吧

我就廢話不多說啦，大家還是直接看代碼吧~

byte[] bUserInfoSearch = new byte[1024 * 10]; //10kb大小
   Marshal.Copy(lpBuffer, bUserInfoSearch, 0, bUserInfoSearch.Length);
   string strUserInfoSearch = System.Text.Encoding.UTF8.GetString(bUserInfoSearch);
   CUserInfoSearch m_JsonUserInfoSearch = new CUserInfoSearch();
   //序列化這個(gè)字符串
   m_JsonUserInfoSearch = JsonConvert.DeserializeObject<CUserInfoSearch>(strUserInfoSearch);
  public class CUserInfoSearch
  {
   public CUserInfoSearchContent UserInfoSearch { get; set; }
  }
  public class CUserInfoSearchContent
  {
   public string searchID { get; set; }
   public string responseStatusStrg { get; set; } //查詢狀態(tài)字符串描述: OK-查詢結(jié)束, MORE-還有數(shù)據(jù)等待查詢, NO MATCH-沒有匹配數(shù)據(jù)
   public int numOfMatches { get; set; } //本次返回的記錄條數(shù)
 　　　　　　
   public int totalMatches { get; set; } //符合條件的記錄總條數(shù)
public List<CUserInfoContent> UserInfo { get; set; } }
 public class CUserInfoContent
  {
   public string employeeNo { get; set; }
   public string name { get; set; }
   public string userType { get; set; }
   public bool closeDelayEnabled { get; set; }
   public CVaild Valid { get; set; }
   public string belongGroup { get; set; }
   public string password { get; set; }
   public string doorRight { get; set; }
   public List<CRightPlan> RightPlan { get; set; }
   public int maxOpenDoorTime { get; set; }
   public int openDoorTime { get; set; }
   public int roomNumber { get; set; }
   public int floorNumber { get; set; }
   public bool doubleLockRight { get; set; }
   public bool alwaysOpenRight { get; set; }
   public bool localUIRight { get; set; }
   public string userVerifyMode { get; set; }
   public bool checkUser { get; set; }
  }
  public class CVaild
  {
   public bool enable { get; set; }
   public string beginTime { get; set; }
   public string endTime { get; set; }
   public string timeType { get; set; }
  }
  public class CRightPlan
  {
   public int doorNo { get; set; }
   public string planTemplateNo { get; set; }
  }

json字符串為

{
 "UserInfoSearch": {
  "searchID": "1",
  "responseStatusStrg": "MORE",
  "numOfMatches": 2,
  "totalMatches": 4,
  "UserInfo": [{
    "employeeNo": "1",

    },
    "belongGroup": "",

      "planTemplateNo": "1"
     }],
    "maxOpenDoorTime": 0,

     "endTime": "0-00-00T00:00:00",
     "timeType": "local"
    },
    "belongGroup": "",
    "password": "",
    "doorRight": "1",
    "RightPlan": [{
      "doorNo": 1,
      "planTemplateNo": "1"
     }],
    "maxOpenDoorTime": 0,
    "openDoorTime": 0,
    "roomNumber": 1,
    "floorNumber": 1,
    "localUIRight": false,
    "numOfCard": 0,
    "numOfFP": 0,
    "numOfFace": 1
   }]
 }
}

補(bǔ)充：C#使用NewtonSoft操作Json實(shí)戰(zhàn)

上代碼~
