WebRequest Equivalent to CURL command

Question

I am banging my head against a wall trying to convert a working curl command to a c# WebRequest.

I have read through quite a few postings and I was pretty sure I had the code right but it still will not work.

Can anyone see what I am doing wrong please?

Here is the working curl command:

curl -k -u x:reallylongstring -H "Content-Type: application/json"  https://api.somewhere.com/desk/external_api/v1/customers.json

And this is the code I have written in c#:

WebRequest wrGETURL;
wrGETURL = WebRequest.Create("https://api.somewhere.com/desk/external_api/v1/customers.json");
wrGETURL.Method = "GET";
wrGETURL.ContentType = "application/json"; 
wrGETURL.Credentials = new NetworkCredential("x", "reallylongstring");
Stream objStream = wrGETURL.GetResponse().GetResponseStream();
StreamReader objReader = new StreamReader(objStream);
string responseFromServer = objReader.ReadToEnd();

But the api responds:

The remote server returned an error: (406) Not Acceptable.

Any help would be much appreciated!

Thanks

Based on Nikolaos's pointers I appear to have fixed this with the following code:

public static gta_allCustomersResponse gta_AllCustomers()
    {
        var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://api.somewhere.com/desk/external_api/v1/customers.json");
        httpWebRequest.ContentType = "application/json";
        httpWebRequest.Accept = "*/*";
        httpWebRequest.Method = "GET";
        httpWebRequest.Headers.Add("Authorization", "Basic reallylongstring");

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();

        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            gta_allCustomersResponse answer =  JsonConvert.DeserializeObject<gta_allCustomersResponse>(streamReader.ReadToEnd());
            return answer;
        }
    }
