"Accessed JArray values with invalid key value: "id". Int32 array index expected" crash when gathering json

I am currently gathering json from a url but i recieve an error that i have never experienced before looking like this:

Accessed JArray values with invalid key value: "id". Int32 array index expected

This is how the JSON looks (an example of 1 item, there are more of these):

[  
   {  
      "id":19205,
      "company_id":2658,
      "external_link":"",
      "county":{  
         "id":12,
         "name":" ",
         "future":"",
         "infrastructure":""
      },
      "category":{  
         "id":5,
         "name":""
      },
      "company":{  
         "id":2658,
         "company_info":[  

         ]
      },
      "merits":[  

      ],
      "reqs":[  
         {  
            "id":56548,
            "ad_id":19205
         },
         {  
            "id":56549,
            "ad_id":19205
         },
         {  
            "id":56550,
            "ad_id":19205
         },
         {  
            "id":56551,
            "ad_id":19205
         },
         {  
            "id":56552,
            "ad_id":19205
         }
      ],
      "contact":null
   }
]

How i gather the json:

static public async Task<JArray> getData()
    {
        var httpClientRequest = new HttpClient();
        try
        {
            var result = await httpClientRequest.GetAsync("https://mydata.com");
            var resultString = await result.Content.ReadAsStringAsync();
            var jsonResult = JArray.Parse(resultString);
            return jsonResult;
        }

        catch
        {
            return null;
        }
    }

How i try to use it and where the error occurs:

var getData = await dataApi.getData();

foreach (var jobs in getData)
{       
    System.Diagnostics.Debug.WriteLine(getData["id"].ToString()); //CRASH: `Accessed JArray values with invalid key value: "id". Int32 array index expected
}

How would I need to adjust my code in order to successfully gather the JSON?

You are trying to reference the array within the for loop, try:

System.Diagnostics.Debug.WriteLine(jobs["id"].ToString());

or 

System.Diagnostics.Debug.WriteLine(jobs.id.ToString());

You might also need to parse your Json for it to be interpreted by c# code see this post about parsing Json with c#
