Hi Experts,

using JSON DeserializeAnonymousType method[^]
I managed to get json file using HttpWebRequest.
Everything works just fine for one url/file , but I tried the exaact same code with different anonymous type it gives me the error:
invalid anonymous type member declarator. Anonymous type members must be declared with a member assignment, simple name or member access
Please check my code below
Thanks!

What I have tried:

JSON file that works fine:

{
  "makes": [
    {
      "id": "acura",
      "name": "Acura"
    },
    {
      "id": "audi",
      "name": "Audi"
    },
.......

The code to get the data:

string url = "url";
HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
httpWebRequest.Method = WebRequestMethods.Http.Get;
httpWebRequest.Accept = "application/json; charset=utf-8";
string JSONfile;
var response = (HttpWebResponse)httpWebRequest.GetResponse();
using (var sr = new StreamReader(response.GetResponseStream()))
{ JSONfile = sr.ReadToEnd(); }
var mytb = JsonConvert.DeserializeAnonymousType(JSONfile, new { Makes = default(DataTable) }).Makes;

Another JSON file with almost the same structure:

{
  "vehicle-makes": [
    {
      "id": "acura",
      "name": "Acura",
      "path": "p1"
    },
    {
      "id": "audi",
      "name": "Audi",
      "path": "p2"
    },
......

The code to download the JSON file is the same with the only difference is anonymous type:

string url = "url";
     HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
     httpWebRequest.Method = WebRequestMethods.Http.Get;
     httpWebRequest.Accept = "application/json; charset=utf-8";
     string JSONfile;
     var response = (HttpWebResponse)httpWebRequest.GetResponse();
     using (var sr = new StreamReader(response.GetResponseStream()))
     { JSONfile = sr.ReadToEnd(); }
     var mytb = JsonConvert.DeserializeAnonymousType(JSONfile, new { vehicle-makes = default(DataTable) }).vehicle-makes;

Somehow it doesn't like (vehicle-makes)
