I am trying to deserialize the json string in C#. Following is jsonstring I used. But after deserialize it is giving null value. So what's going wrong with me?

string res = @"{   ""root"":{""EmployeeMaster"":{""EmployeeMasterData"":[{""BasicDetails"":{ ""BasicDetail"":{ ""Action"":""Update"",""EmployeeCode"":""0076"",""L2ManagerCode"":2911}}},{""BasicDetails"":{""BasicDetail"":{ ""Designation"":""Branch Incharge"",""Action"":""Update"",""EmployeeCode"":1786,""SubDepartment"":""Branch Manager"",""Department"":""Operations"",""JOBROLE"":""Branch Manager"",}}},{""DependentDetails"":{""DependentDetail"":{""DateOfBirth"":""1972-07-31"",""DependentName"":""Ramani"",""Action"":""Create"",""EmployeeCode"":2923,""Address"":"""",""RelationshipType"":""Mother"",""Gender"":"""",""IsDependent"":""No""}}},{""ContactDetails"":{""ContactDetail"":[{""AddressLine2"":""Turvekere"",""AddressLine1"":""Hallada Hosahalli"",""Action"":""Update"",""Country"":""India"",""City"":""Tumkur"",""Pincode"":572227},{""AddressLine2"":"""",""AddressLine1"":"""",""Action"":""Update"",""State"":"""",""Country"":"""",""City"":"""",""Pincode"":""""}]}},{""BasicDetails"":{""BasicDetail"":{""Action"":""Create"",""L2ManagerName"":""Ratheesh P R"",""IsDisabled"":""No"",""L1ManagerCode"":2771,""SubDepartment"":""Collection Assistant"",""Gender"":""Male"",""EmploymentType"":""Permanent"",""Department"":""Operations"",""L1ManagerName"":""Arun K K"",""Designation"":""Collection Assistant"",""EmployeeCode"":201021,""L2ManagerCode"":2564,""FirstName"":""Vishnu"",""Title"":""Mr."",""EmploymentStatus"":""Active"",""MiddleName"":"""",""DisabilityType"":"""",""OfficialMailID"":"""",""Nationality"":""IND"",""DateOfRelieving"":"""",""DateOfJoining"":""2022-01-20"",""JOBROLE"":"""",""LastName"":""G"",""BirthDate"":""1995-08-28""}}}]}}}";

It's not working, because the primitive object is invalid. can anyone please help me to create the class file. thanks in advance

try this, it was tested in visual studio

var jsonParsed = JObject.Parse(json); 

List<EmployeeMasterData> employeeMasterData  = jsonParsed["root"]["EmployeeMaster"]
["EmployeeMasterData"].Select(x => AddItems(x)).ToList();

public static EmployeeMasterData AddItems(JToken jt)
{
    var emd = new EmployeeMasterData();
    foreach (var element in ((JObject)jt).Properties())
    {
        if (element.Name == "BasicDetails")
            emd.BasicDetails = element.Value.ToObject<BasicDetails>();
        if (element.Name == "DependentDetails")
            emd.DependentDetails = element.Value.ToObject<DependentDetails>();
        if (element.Name == "ContactDetails")
            emd.ContactDetails = element.Value.ToObject<ContactDetails>();
    }
    return emd;
}

Generally, I would suggest the NewtonSoft JSON library if you are working with JSON. You can serialize and deserialize JSON to class, and class to JSON.

With this library you must not parse JSON by yourself.

JSON Library

CodePudding user response：

First of all, there are some errors in the Json format. There is an incorrect use of the icon. Additionally, if you specify string for Json, the \ add symbol is required for each ".

You do not need to write @ in front of the string this time.

like this

\"DateOfJoining\":\"2022-01-20\"
