Deseralise an object that has property types-CodePudding

{
    "correlationID": "00000000-0000-0000-0000-000000000000",
    "scenarioID": 2,
    "scenarioIsAcceptedInPrinciple": false,
    "valid": false,
    "errors": [
        {
            "errorID": 90,
            "errorText": "For the 1st Employment of the 1st Applicant Please provide a valid Landline"
        },
        {
            "errorID": 22,
            "errorText": "The provided value 'string' is not a valid value for the property 'applicants[0][email]'"
        }
    ]
}

I have this JSON response that is produced from a POST request that I have sent.

I would like to deseralise it so I can call the errorID and errorText and do testing assertions to see if the correct error ID and text came back.

I have got it to work with;

public partial class postRequest
    {
        public bool Valid { get; set; }
        public object Errors { get; set; }
    }

and it returns all of the error, like this;

Standard Output: 
[
  {
    "errorID": 90,
    "errorText": "For the 1st Employment of the 1st Applicant Please provide a valid Landline"
  },
  {
    "errorID": 22,
    "errorText": "The provided value 'string' is not a valid value for the property 'applicants[0][email]'"
  }
]

How would I return just the error ID and error text.,

Thanks

CodePudding user response：

You should create another class for the error.

public class Error
{
    public string ErrorID { get; set; }
    public string ErrorText { get; set; }
}

And then use that in the other class:

public Error[] Errors { get; set; }

Finally you access the errors like:

response.Errors[0].ErrorID

CodePudding user response：

You have to deserialize it like this object :

public class JsonResponse
{
    public bool valid { get; set; }
    public List<Error> errors { get; set; }
}

public class Error
{
    public int errorID { get; set; }
    public string errorText { get; set; }
}

For deserialization:

var data =System.Text.Json.JsonSerializer.Deserialize<JsonResponse>("your json source");

CodePudding user response：

you have a list of errors, not just a one

List<Error> errors = JObject.Parse(json)["errors"].Select(x => x.ToObject<Error>()).ToList();
    
public class Error
{
    public int ErrorID { get; set; }
    public string ErrorText { get; set; }
}

you can see them

foreach (var error in errors)
    {
        Console.WriteLine($"Error Id : {error.ErrorID}, Error Text {error.ErrorText}");
    }
    
    // or
    
    var errId=errors[0].ErrorID;
