stackoverflow search api

Question

我想使用stackoverflow API的搜索方法，根據搜索關鍵字返回結果的json結構，然後在SearchResults div中顯示這些結果（標題，描述和url）。

我是新來的C＃和我第一次嘗試去是這樣的：

protected void searchStockOverflow(string y) 
    { 

     var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://api.stackoverflow.com/1.1/search?intitle="+y); 
     httpWebRequest.ContentType = "text/json"; 
     httpWebRequest.Method = "POST"; 

     using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream())) 
     { 
      string json = "{ \"intitle\": \"" + y + "\"}"; 

      streamWriter.Write(json); 
     } 
     var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse(); 
     using (var streamReader = new StreamReader(httpResponse.GetResponseStream())) 
     { 
      var responseText = streamReader.ReadToEnd(); 

      SearchResults.InnerHtml += "<div style='border:1px solid blue;margin:5px;'>"; 
      SearchResults.InnerHtml += responseText + "<br />"; 
      SearchResults.InnerHtml += "</div><br style='clear:both;' />"; 
     } 
    } 

問題是返回看起來像裝飾符號垃圾 - 我猜是因爲它是序列化，需要進行反序列化？

我肯定會說考慮使用REST客戶端;然而，看看這些問題...通常您想要手動將數據反序列化爲JSON，然後然後通過您的UI代碼運行該數據。例如：

static void SearchStackOverflow(string y) 
{ 
    var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://api.stackoverflow.com/1.1/search?intitle=" + Uri.EscapeDataString(y)); 
    httpWebRequest.AutomaticDecompression = DecompressionMethods.Deflate | DecompressionMethods.GZip; 
    httpWebRequest.Method = "GET"; 
    var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse(); 
    string responseText; 
    using (var streamReader = new StreamReader(httpResponse.GetResponseStream())) 
    { 
     responseText = streamReader.ReadToEnd(); 
    } 
    var result = (SearchResult)new JavaScriptSerializer().Deserialize(responseText, typeof(SearchResult)); 
    .... do something with result ... 
} 
class SearchResult 
{ 
    public List<Question> questions { get; set; } 
} 
class Question 
{ 
    public string title { get; set; } 
    public int answer_count { get; set; } 
} 

從System.Web.Extensions.dll

使用JavaScriptSerializer

不幸的是，我在我的Mac上，無法對您的代碼運行測試。您可能想要檢查頁面和返回的響應流的字符編碼。如果它們不匹配;它可能會導致來自響應流的字符被錯誤地渲染，因此您看到垃圾。
