REST

The following code works for basic authentication.

public async Task RunAsync(string name, string value)
{
using (var handler = new HttpClientHandler { UseDefaultCredentials = true })
using (var client = new HttpClient(handler))
{
var byteArray = Encoding.ASCII.GetBytes("username:password");
client.DefaultRequestHeaders.Authorization = new System.Net.Http.Headers.AuthenticationHeaderValue("Basic", Convert.ToBase64String(byteArray));
var urlRestGet = HomeController.url;
client.BaseAddress = new Uri(urlRestGet + "?name=" + name + "&value=" + value + "");
client.DefaultRequestHeaders.Accept.Clear();
**1. if(HomeController.contentType.ToLower()=="xml"){
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/xml"));
}**
else if (HomeController.contentType.ToLower() == "json")
{
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
}

HttpResponseMessage response = await client.GetAsync(urlRestGet + "?name=" + name + "&value=" + value + "");

if (response.IsSuccessStatusCode)
{
//Get the response
loginJsonString = await response.Content.ReadAsStringAsync();

//Converting to xml
using (var stream = new MemoryStream(Encoding.ASCII.GetBytes(loginJsonString)))
{
var output = new XmlDictionaryReaderQuotas();
xmlResult = XDocument.Load(JsonReaderWriterFactory.CreateJsonReader(stream, output)).ToString();
}
}
}
}

What I have tried:

1) If the content type is application/xml am I correct to use line 1 part in the code.

2) How can I make this code more generic. (when the authentication type is different eg: tokenized or cookiebased how can I change this.)
