HttpWebRequest從SharePoint服務器獲得不同於一切的響應

我試圖連接到Sharepoint服務器並在C＃中獲取RSS源。這似乎是一個足夠簡單的任務，但是由於某種原因，當我發送一個HttpWebRequest時，Sharepoint向我發送了一個不同的響應，這個響應與我在瀏覽器中訪問這個feed時得到的結果不同。具體來說，它返回沒有任何s的feed。HttpWebRequest從SharePoint服務器獲得不同於一切的響應

對提出請求的代碼如下：

HttpWebRequest request = WebRequest.Create(URL) as HttpWebRequest; 
request.Credentials = CredentialCache.DefaultCredentials; //NTLM 

using (HttpWebResponse response = request.GetResponse() as HttpWebResponse) { 
    Stream responseStream = response.GetResponseStream(); 
    // debug: dump the response. 
    System.Diagnostics.Debug.WriteLine((new StreamReader(responseStream)).ReadToEnd()); 
...

在測試這個代碼，我試了一下在公共RSS提要，並能正常工作。我啓動了Wireshark來看看，看看是否有一些關於用C＃發送的請求不同，請求和響應是這樣的：

GET /Test_Blog_B/_layouts/15/listfeed.aspx?List=%7B5600FFF4-50CD-47C5-BEBC-602874E73748%7D HTTP/1.1

    </rss>

然而，一切我嘗試得到這個響應（捲曲輸出，剪斷了一些標題爲簡潔起見）

這是一個乾淨的一個正常的SharePoint博客安裝SharePoint 2013年打開該飼料中的瀏覽器提供同樣的結果捲曲，所以我不能看到的我的C＃代碼被提供了不同的東西。

隨着這種情況的原因任何幫助表示讚賞，感謝

因此，解決辦法是，CredentialCache.DefaultCredentials需要什麼運行IIS的服務器，這不是我自己的憑證的憑證。給代碼我自己的憑據工作，並給出預期的輸出。
