C＃コンソールアプリケーションでSOAPリクエストを送信するときのエラー

Question

C＃コンソールアプリケーションでリクエストを投稿しようとしていますが、このエラーが発生しています。リクエストがSOAPUIで動作しているので、WSDLファイルがないので、コードに直接XMLをロードする必要があります（これはエラーがどこから来たのかと思われます）。

コンソールアプリケーションの出力は以下の通りです：ここでは

を私はこのSOAPリクエストを送信するために使用していますC＃コンソールアプリケーションで次のように働いている

SOAPUI要求です。

      Program obj = new Program(); 
      obj.createSOAPWebRequest(); 
     } 

     //Create the method that returns the HttpWebRequest 
     public void createSOAPWebRequest() 
     { 

      //Making the Web Request 
      HttpWebRequest Req = (HttpWebRequest)WebRequest.Create(@"http://127.1.1.0:9090/spg"); 

      //Content Type 
      Req.ContentType = "text/xml;charset=utf-8"; 
      Req.Accept = "text/xml"; 

      //HTTP Method 
      Req.Method = "POST"; 

      //SOAP Action 
      Req.Headers.Add("SOAPAction", "\"SOAPAction:urn#LstSbr\""); 

      NetworkCredential creds = new NetworkCredential("username", "pass"); 
      Req.Credentials = creds;

ここは私がWebサービスに投稿するのに使う私の基本的な方法です。

static XNamespace soapNs = "http://schemas.xmlsoap.org/soap/envelope/"; 
static XNamespace topNs = "Company.WebService"; 

private System.Net.HttpWebResponse ExecutePost(string webserviceUrl, string soapAction, string postData) { 
    var webReq = (HttpWebRequest)WebRequest.Create(webserviceUrl); 
    webReq.AutomaticDecompression = DecompressionMethods.Deflate | DecompressionMethods.GZip; 
    webReq.ContentType = "text/xml;charset=UTF-8"; 
    webReq.UserAgent = "Opera/12.02 (Android 4.1; Linux; Opera Mobi/ADR-1111101157; U; en-US) Presto/2.9.201 Version/12.02"; 
    webReq.Referer = "http://www.company.com"; 
    webReq.Headers.Add("SOAPAction", soapAction); 
    webReq.Method = "POST"; 

    var encoded = Encoding.UTF8.GetBytes(postData); 
    webReq.ContentLength = encoded.Length; 
    var dataStream = webReq.GetRequestStream(); 
    dataStream.Write(encoded, 0, encoded.Length); 
    dataStream.Close(); 

    System.Net.WebResponse response; 
    try { response = webReq.GetResponse(); } 
    catch { 
     ("Unable to post:\n" + postData).Dump(); 
     throw; 
    } 

    return response as System.Net.HttpWebResponse; 
} 

私は、これが私の必要とすることを何でもしたいものを構築することができます。たとえば、ここで私はそれをどのように使用するかです。

private void CreateTransaction(string webServiceUrl, string ticket, double costPerUnit) { 
    string soapAction = "Company.WebService/ICompanyWebService/CreatePurchaseTransaction"; 
    var soapEnvelope = new XElement(soapNs + "Envelope", 
         new XAttribute(XNamespace.Xmlns + "soapenv", "http://schemas.xmlsoap.org/soap/envelope/"), 
         new XAttribute(XNamespace.Xmlns + "top", "Company.WebService"),      
        new XElement(soapNs + "Body", 
         new XElement(topNs + "CreatePurchaseTransaction", 
          new XElement(topNs + "command", 
           new XElement(topNs + "BillTransaction", "true"), 
           new XElement(topNs + "BillingComments", "Created By C# Code"), 
           new XElement(topNs + "Department", "Development"), 
           new XElement(topNs + "LineItems", GetManualPurchaseLineItems(topNs, costPerUnit)),         
           new XElement(topNs + "Surcharge", "42.21"), 
           new XElement(topNs + "Tax", "true"), 
           new XElement(topNs + "TransactionDate", DateTime.Now.ToString("yyyy-MM-dd")) 
        )))); 

    var webResp = ExecutePost(webServiceUrl, soapAction, soapEnvelope.ToString()); 
    if (webResp.StatusCode != HttpStatusCode.OK) 
     throw new Exception("Unable To Create The Transaction"); 

    var sr = new StreamReader(webResp.GetResponseStream()); 
    var xDoc = XDocument.Parse(sr.ReadToEnd()); 
    var result = xDoc.Descendants(topNs + "ResultType").Single(); 
    if (result.Value.Equals("Success", StringComparison.CurrentCultureIgnoreCase) == false) 
     throw new Exception("Unable to post the purchase transaction. Look in the xDoc for more details."); 
} 

private IEnumerable<XElement> GetManualPurchaseLineItems(XNamespace topNs, double costPerUnit) { 
    var lineItems = new List<XElement>(); 

    lineItems.Add(new XElement(topNs + "PurchaseLineItem", 
         new XElement(topNs + "Count", "5"), 
         new XElement(topNs + "ExpenseClass", "Tech Time"), 
         new XElement(topNs + "ItemName", "Brushing and Flossing"), 
         new XElement(topNs + "Location", "Your House"), 
         new XElement(topNs + "UnitCost", costPerUnit.ToString("#.00")))); 

    return lineItems; 
} 

これをコンソールアプリケーションに適用する必要がありますが、これが役立つでしょうか？
