這是我的代碼：

WebRequest request = HttpWebRequest.Create(url); 
using (WebResponse response = request.GetResponse()) 
{ 
    using (Stream stream = response.GetResponseStream()) 
    { 
     stream.Flush(); 
     stream.Position = 0; 
     XmlDocument doc = new XmlDocument(); 
     doc.Load(stream); 
    } 
}

後，我跑我得到的代碼Doc.Load中的異常 - 「根級別的數據無效。第1行，第1行「當解析XML時。

如何克服這個錯誤，？我嘗試了所有方法。因爲XML初始化標題格式錯誤。我遇到這個錯誤，如何解決這個問題？

什麼是響應編碼？ –

你會得到一個不同的錯誤 - XML無效，因爲它沒有關於「LoadReportViewModel」或「ArrayOfLoanReportViewModel」的關閉元素。你有沒有把'stream'讀到'string'來看看它的樣子？ –

即使使用有效的XML，我也遇到同樣的問題，看起來XmlDocument.Load（Stream）方法表現得很奇怪。將流轉換爲字符串並使用XmlDocument.LoadXml（String）後，它工作正常。 – LInsoDeTeh

如果您發佈的XML是您收到的整個XML，那麼它缺少根級別元素。嘗試使用沿着這樣的線XmlDocumentFragment

的東西應該工作：

var doc = new XmlDocument(); 
var xml = doc.CreateDocumentFragment(); 
xml.InnerXml = stream;

我終於解決了這個問題。對於面臨此問題的其他人有用。

工作代碼：

   WebRequest request = WebRequest.Create(url); 
       // If required by the server, set the credentials.r 
       request.Credentials = CredentialCache.DefaultCredentials; 
       request.ContentType = "application/xml; charset=utf-8"; 
       // Get the response. 
       HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
       //// Display the status. 
       //Console.WriteLine(response.StatusDescription); 
       //// Get the stream containing content returned by the server. 
       Stream dataStream = response.GetResponseStream(); 
       // Open the stream using a StreamReader for easy access. 
       StreamReader reader = new StreamReader(dataStream); 
       // Read the content. 
       string responseFromServer = reader.ReadToEnd(); 

       DataSet ds = new DataSet(); 

       ds.ReadXml(new StringReader(responseFromServer)); 

       if (ds.Tables[0].Rows.Count != 0) 
       { 
        for (int i = 0; i < ds.Tables[0].Rows.Count; i++) 
        { 
         strArrNames.Add(ds.Tables[0].Rows[i]["Name"].ToString()); 
         strArrEmails.Add(ds.Tables[0].Rows[i]["Email"].ToString()); 
         strArrTitles.Add(ds.Tables[0].Rows[i]["Title"].ToString()); 
         strArrBalanceDays.Add(ds.Tables[0].Rows[i]["BalanceDays"].ToString()); 
         strArrLoanDueDates.Add(ds.Tables[0].Rows[i]["loanDueDate"].ToString()); 

        } 

        overduestatus = true; 

       }

感謝所有..
