I come back to you, because after having tried everything I can't manage to deserialize the following json:

{
    "totalcount": 2,
    "count": 2,
    "sort": "1",
    "order": "ASC",
    "data": [
        {
            "1": "S011908",
            "80": "Root entity",
            "31": "Hors-service > En attente réinitialisation",
            "70": "TARTUF",
            "id": 1333,
            "itemtype": "Computer"
        },
        {
            "1": "S01B2101",
            "80": "Root entity",
            "31": "Fonctionnel > Utilisé",
            "70": "FILOU",
            "id": 1360,
            "itemtype": "Computer"
        }
    ],
    "content-range": "0-1/2"
}

It is a json obtained from the API of GLPI, for the connection no problem, I have my accesses I manage to recover the list in my _repository

                return View(new List<Glpi>());
            }
        }
    }
}

At the level of the model I think to have defined as it is necessary, the doubt is at the level of Datum!

            return list;
        }
    }
}

So, as I understand, I can't get my json to deserialize and put it in my list.

I get the following message in Visual Studio in my breakpoint.

List list = _repository.GetAllList().ToList(); error CS0305: L'utilisation du type générique 'List' nécessite des arguments de type 1 Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[Portail_DIN.Models.Glpi]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly. To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object. Path 'totalcount', line 1, position 14.

Thank you in advance for your insights

fix this

 public Glpi GetAllList()
 {
return JsonConvert.DeserializeObject<Glpi>(_savedFileGL
List<Glpi> list =PI);
 }

and if you need only list of data you can fix action too

 public ActionResult GLPI()
        {
            try
            {
                List<Glpi> list = _repository.GetAllList();
                return View(list.Data);
            }

CodePudding user response：

I can't figure out this code. I'm new to c#, but I think there's a typo, Thanks for your help

public Glpi GetAllList()
 {
return JsonConvert.DeserializeObject<Glpi>(_savedFileGL
List<Glpi> list =PI);
 }
