如何從Spotify Web API獲取藝術家的前5個專輯？

Question

我正在嘗試使用ASP.NET MVC 4和C＃構建一個網站，以使用Spotify web api搜索音樂藝術家的前5個專輯。

這是到目前爲止我的代碼：

public ActionResult Result(string Artist) 
    { 
     var httpClient = new HttpClient(); 
     httpClient.BaseAddress = new Uri("https://api.spotify.com/"); 
     // what goes here to authenticate and get the info? 

     return View(); 
    } 

我找不到，告訴我如何進行身份驗證，然後使用C＃檢索信息。

編輯：我應該提到，我是這個東西的絕對初學者，雖然我讀過spotify API參考，但它並沒有幫助我，因爲它沒有解釋足夠的細節。

例如，web api用戶指南討論GET，POST等，但沒有給出任何代碼來幫助解釋如何使用它。在那裏唯一的代碼是：

$ curl -H "Authorization: Basic Yjc...cK" -d grant_type=refresh_token -d refresh_token=AQD...f0 "https://accounts.spotify.com/api/token" 

{ 
    "error": "invalid_client", 
    "error_description": "Invalid client secret" 
} 

這是令人困惑的我，因爲我不知道放在哪裏，我不知道用什麼語言代碼等

有沒有C＃示例，我可以找到。即使這些代碼示例都是javascript，但它並不能幫助我。
