Desrializing jsonresult throws error in razor pages.

Question

Hi,

I have a json result like shown below,

"{\r\n  \"AccessRights\": [],\r\n  \
"ADAttributes\": [
\r\n    {\r\n      \
"AD\": \"teenajohn\",\r\n      \
"ADFull\": \"\",\r\n      \
"DisplayName\": \"Teena John\",\r\n      \
"FirstName\": \"Teena\",\r\n      \
"Initials\": \"\",\r\n      \
"EmployeeNumber\": \"1111111\",\r\n      \
"LastName\": \"John\",\r\n      \
"EmailAddress\": \"******@gmail.com\",\r\n      \
"Department\": \"Information Systems\",\r\n      \
"Title\": \"System Analyst\",\r\n      \
"BusinessPhone2\": \"6666111111\",\r\n      \
"Mobile\": \"\",\r\n      \
"CleanMobile\": \"\",\r\n      \
"Okta\": \"******@gmail.com\"\r\n    }\r\n  
],
\r\n  \
"OktaAttributes\": 
[\r\n    {\r\n      \
"Okta\": \"******@gmail.com\",\r\n      \
"AD\": \"teenajohn\",\r\n      \
"EmployeeNumber\": \"1111111\",\r\n      \
"FirstName\": \"Teena\",\r\n      \
"LastName\": \"John\",\r\n      \
"Email\": \"******@gmail.com\",\r\n      \
"SecondEmail\": \"\",\r\n      \
"ManagerAD\": \"\",\r\n      \
"ManagerEmail\": \"\",\r\n      \
"HRAdvisor\": \"\",\r\n      \
"Title\": \"System Analyst\",\r\n      \
"RockFunction\": \"\",\r\n      \
"Mobile\": \"\",\r\n      }\r\n  
],\r\n  \
"IsPublic\": false,\r\n  \
"AuthenticateType\": 1\r\n
}"

To reterive the ADAttributes like AD, DisplayName etc i created a Model Class like this

 public class AuthenticateUserInfo
    {
        public Dictionary<string, ADUserInfo>? ADAttributes { get; set; }
        public Dictionary<string, OktaUserInfo>? OktaAttributes { get; set; }

    }

    public class ADUserInfo
    {
        public string AD { get; set; }
        public string ADFull { get; set; }      
        public string DisplayName { get; set; }
        public string FirstName { get; set; }
        public string Initials { get; set; }
        public string EmployeeNumber { get; set; }
        public string LastName { get; set; }
        public string EmailAddress { get; set; }
        public string Department { get; set; }
        public string Title { get; set; }
        public string Manager { get; set; }
    }

    public class OktaUserInfo
    {

    }

And used json deserialize in my .cshtml.cs file to retrieve those details.

But system throws error

 if (result.Success)
                {
                    Console.WriteLine("Success");
                    string jsonString = result.JsonResult.ToString();
                    AuthenticateUserInfo AuthenticateUserInfo = JsonSerializer.Deserialize<AuthenticateUserInfo>(jsonString);
               
                    return Redirect("/Privacy");

                }

could not figure out where i am going wrong.

Any help would be appreciated.Thanks!

Hi @Blooming Developer ,

From your description of this question, I think you want to desrialize json to objects. So you can check this simple demo.

Let's remove escape characters from this json:

{
    "AccessRights": [],
    "ADAttributes": [
        {
            "AD": "teenajohn",
            "ADFull": "",
            "DisplayName": "Teena John",
            "FirstName": "Teena",
            "Initials": "",
            "EmployeeNumber": "1111111",
            "LastName": "John",
            "EmailAddress": "******@gmail.com",
            "Department": "Information Systems",
            "Title": "System Analyst",
            "BusinessPhone2": "6666111111",
            "Mobile": "",
            "CleanMobile": "",
            "Okta": "******@gmail.com"
        }
    ],
    "OktaAttributes": [
        {
            "Okta": "******@gmail.com",
            "AD": "teenajohn",
            "EmployeeNumber": "1111111",
            "FirstName": "Teena",
            "LastName": "John",
            "Email": "******@gmail.com",
            "SecondEmail": "",
            "ManagerAD": "",
            "ManagerEmail": "",
            "HRAdvisor": "",
            "Title": "System Analyst",
            "RockFunction": "",
            "Mobile": "",
            
        }
    ],
    "IsPublic": false,
    "AuthenticateType": 1
}

There are five properties in this json: AccessRights,ADAttributes,OktaAttributes,IsPublic,AuthenticateType.

So you can create a class contains these properties.

AuthenticateUserInfo

public class AuthenticateUserInfo
    {
        public List<AccessRights> accessRights { get; set; }
        public List<ADAttributes> adAttributes { get; set; }
        public List<OktaAttributes> oktaAttributes { get; set; }
        public bool IsPublic { get; set; }
        public int AuthenticateType { get; set; }
    }

ADAttributes

public class ADAttributes
    {
        public string AD { get; set; }
        public string ADFull { get; set; }
        public string DisplayName { get; set; }
        public string FirstName { get; set; }
        public string Initials { get; set; }
        public string EmployeeNumber { get; set; }
        public string LastName { get; set; }
        public string EmailAddress { get; set; }
        public string Department { get; set; }
        public string Title { get; set; }
        public string Manager { get; set; }

        public string BusinessPhone2 { get; set; }

        public string Mobile { get; set; }

        public string CleanMobile { get; set; }

        public string Okta { get; set; }
    }

OktaAttributes

 public class OktaAttributes
{
    public string Okta { get; set; }
    public string AD { get; set; }
    public string EmployeeNumber { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Email { get; set; }
    public string SecondEmail { get; set; }
    public string ManagerAD { get; set; }
    public string ManagerEmail { get; set; }
    public string HRAdvisor { get; set; }
    public string Title { get; set; }
    public string RockFunction { get; set; }
    public string Mobile { get; set; }
}

Then you can use:

AuthenticateUserInfo AuthenticateUserInfo = JsonConvert.DeserializeObject<AuthenticateUserInfo>(content);

to get the value.
