I have a custom model CustomActionResult and it add “is-success” and “message” to the end of data I tried CustomActionResult<PostViewModel> but it didn’t work either.

My data format is like this:

{
    "data": 
       [
        {
            "title": "test1",
            "body": "body",
            "author": null,
            "id": 1,
            "createdDate": "0001-01-01T00:00:00",
            "updatedDate": "0001-01-01T00:00:00"
        },
        {
            "title": "test1",
            "body": "body1",
            "author": null,
            "id": 2,
            "createdDate": "0001-01-01T00:00:00",
            "updatedDate": "0001-01-01T00:00:00"
        }
     ],
     "isSuccess": true,
     "message": null
}

PostViewModel :

public class CustomActionResult
{
    public bool IsSuccess { get; set; }
    public string Message { get; set; }
}

public class CustomActionResult<T> : CustomActionResult
{
    public T Data { get; set; }
}

CustomActionResult:

public class CustomActionResult
{
    public bool IsSuccess { get; set; }
    public string Message { get; set; }
}

public class CustomActionResult<T> : CustomActionResult
{
    public T Data { get; set; }
}
