Web APIからこのJsonを受け取る方法は？

Question

私はこのような構造..

Clienteサイド<持っている - >ウェブアピ戻る - - >ウェブアピフロント<>データベースだから、

、私のウェブアピ戻る私にJSONを送信すると、私が知っているドントを結果を得る方法。

データベースとの接続が表示されません。

Web Api Frontでは、var data = response.Content.ReadAsStringAsync().Result;という行は、すべて正しい値のJson Arrayを提供します。しかし、私はクライアント側のApiCallにこれをどのように送るのか分かりません。

返品には何が必要ですか？

public class ApiCall 
{ 
    static readonly string ApiUrl = "http://Localhost:1762/api/{0}/{1}?nomePesquisa={2}&nomeMae={3}&nomePai={4}&dtNasc={5}&nrg={6}&ncpf={7}"; 


    //buscar os dados com os parametros digitados 
    public async Task<T> GetResponse<T>(string controller, string method, string nomepesquisa, 
     string nomemae, string nomepai, string dtnasc, string nrg, string ncpf) where T : class 
    { 
     var client = new System.Net.Http.HttpClient(); 

     //Definide o Header de resultado para JSON, para evitar que seja retornado um HTML ou XML 
     client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 

     var urllink = string.Format(ApiUrl, controller, method, nomepesquisa, nomemae, nomepai, dtnasc, nrg, ncpf); 
     var response = await client.GetAsync(urllink); 

     //Lê a string retornada 
     var JsonResult = response.Content.ReadAsStringAsync().Result; 

     if (typeof(T) == typeof(string)) 
      return null; 

     //Converte o resultado Json para uma Classe utilizando as Libs do Newtonsoft.Json 
     var rootobject = JsonConvert.DeserializeObject<T>(JsonResult); 
     return rootobject; 
    } 

}

ウェブAPIバックエンド[サービスは、Webアピフロントを呼び出します]返されますIEnumerable<Envolvido>

ウェブアピフロントエンドは、Webアピバックエンドを呼び出すとき、それはちょうどそれがリスト、コレクション、配列も、IEnumerable<Envolvido>に割り当て可能である何かにそれをデシリアライズする必要がある...など

//...other code removed for brevity 
if (response.IsSuccessStatusCode) 
{ 
    var data = response.Content.ReadAsAsync<List<Envolvido>>().Result; 
    return data; 
}
