将 json 响应转换为 .net 中的动态特定 object C#

Question

I'm working on .NET Core where I'm trying to masking some sensitive data like emailid , password , etc.. I want all my json response data keys or properties name should be in lowercase for that I'm using one of the feature of Newtonsoft eg ContractResolver which helps us to customize property name. But it seems, it only works with generic class type eg

class customer
{
   public string firstName { get; set; } 
}

but it not working when we have json string eg

{\n   \n    \"firstName\": \"Testbusiness\",\n    \"lastName\": \"business\",\n}

now i'm looking for how to convert json response to specific object type dynamically so that i can pass that object to contractResolver checkout below code.

public class LowerCaseResolver : DefaultContractResolver
{
   protected override string ResolvePropertyName(string propertyName)
    {
        return propertyName.ToLower();
    }
}

using Newtonsoft.Json;
using SerializationContractResolverExample.ContractResolver;
using System;

namespace SerializationContractResolverExample
{
    class Program
    {
        static void Main(string[] args)
        {
            CustomerInfo customerInfo = new CustomerInfo()
            {
                FirstName = "Sukhpinder",
                LastName = "Singh",
                MobileNumbers = new System.Collections.Generic.List<string>() {
                 "33443434343"
                }
            };

            var sestting = new JsonSerializerSettings
            {
                ContractResolver = new LowerCaseResolver()
            };

            // need to convert below response to dynamic generic type 
            string tem1 = "{\n    \"lmsUserId\": 10268,\n    \"landlordProfileId\": \"2ea81674-6ca6-478c-a9c6-fefbe9572f28\",\n    \"firstName\": \"Testbusiness\",\n    \"lastName\": \"business\",\n    \"email\": \"yesteluydi@vusra.com\",\n    \"createdBy\": 1551,\n    \"createdDate\": \"2022-05-05T17:05:10.37\",\n    \"user\": null,\n    \"linkedLLCs\": null,\n    \"ssn\": null,\n    \"accountTypeId\": 2,\n    \"completeLater\": false\n}";

            var responseLowerCase = JsonConvert.SerializeObject(tem1, Formatting.Indented, sestting);  //Not working
            
            var responseLowerCase = JsonConvert.SerializeObject(customerInfo, Formatting.Indented, sestting); //Working Fine 

            Console.WriteLine(responseLowerCase);

            Console.ReadLine();
        }
    }
}

You can try to use JsonConvert.DeserializeObject to convert tem1 to Object .

string tem1 = "{\n    \"lmsUserId\": 10268,\n    \"landlordProfileId\": \"2ea81674-6ca6-478c-a9c6-fefbe9572f28\",\n    \"firstName\": \"Testbusiness\",\n    \"lastName\": \"business\",\n    \"email\": \"yesteluydi@vusra.com\",\n    \"createdBy\": 1551,\n    \"createdDate\": \"2022-05-05T17:05:10.37\",\n    \"user\": null,\n    \"linkedLLCs\": null,\n    \"ssn\": null,\n    \"accountTypeId\": 2,\n    \"completeLater\": false\n}";
   var s = JsonConvert.DeserializeObject<Object>(tem1);

result:
