{

    public class Params2
    {
        public string service { get; set; }
        public string year { get; set; }
        public string login_ldap_key_name { get; set; }
        public string login_ldap_key_value { get; set; }
        public string email_key_name { get; set; }
        public string photo_key_name { get; set; }
        public string cellular_key_name { get; set; }
    }

    public class Params
    {
        public string year { get; set; }
       // public Params2 Params { get; set; }
    }

    public class Meta
    {
        public string service { get; set; }
        public int row_count { get; set; }
        public string year { get; set; }
        public Params @params { get; set; }
    }

    public class Data
    {
        public string id { get; set; }
        public string name { get; set; }
        public string surname { get; set; }
        public string login { get; set; }
        public string mail { get; set; }
        public string photo { get; set; }
        public string cell_phone { get; set; }
        public string annee_universitaire { get; set; }
        public string code_formation { get; set; }
        public string lib1_formation { get; set; }
        public string lib2_formation { get; set; }
        public string base_url_photo { get; set; }
        public string personal_email { get; set; }
        public string student_id { get; set; }
        public string diplome_type { get; set; }
        public string diplome_code { get; set; }
        public string diplome_lib { get; set; }
        public string administrative_status { get; set; }
    }

    public class RootObject
    {
        public Meta meta { get; set; }
        public Data data { get; set; }
    }


}

but i get this error :

 Unhandled Exception:

 Newtonsoft.Json.JsonSerializationException: Cannot deserialize the current 
 JSON object
 (e.g. {"name":"value"}) into type 
 'System.Collections.Generic.List`1[University.Data.JSON1]'
  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 l
 ike an array or List<T>) 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 'meta', line 1, position 8. a eu lieu 

My Json is :

{
  "meta": {
    "service": "student",
    "row_count": 18,
    "year": "2017",
    "params": {
      "year": "2017",

Answer 1

Just enclose your response with [] backet

Answer 2

Change

JsonConvert.DeserializeObject<List<JSON1>>(result_Student.Content);

to

JsonConvert.DeserializeObject<JSON1>(result_Student.Content);

The JSON you have included in the collection is not an array/collection/list but a single object.
