Senden von Dateien mit Httpwebrequest

Question

Hallo, ich versuche XML-Dateien aus einem Ordner mit Webservice in einen anderen Ordner auf meinem lokalen Computer zu senden, Dateien erfolgreich gesendet werden und die Anwendung wird normal geschlossen, aber das Problem ist, dass Dateien für immer in geändert wird der Zielordner und wenn ich versuche, den Webservice erneut anzurufen gibt es eine Ausnahmezeit. hier ist mein Code

public void SendC_XML(string path, string queueID, string application, string servicewTMURI) 
    { 


     HttpWebRequest httpWebRequest2 = null; 
     //Stream memStream = null; 
     //FileStream fileStream = null; 

     String[] listOfFiles = Directory.GetFiles(path, "*.xml"); 






     for (int i = 0; i < listOfFiles.Length; i++) 
     { 
      try 
      { 
       MyLog.Add("found path " + listOfFiles[i]); 

       string[] ImagesArray = listOfFiles[i].Split('\\'); 
       string ImageName = ImagesArray[ImagesArray.Length - 1]; 
       int index = ImageName.IndexOf("."); 
       if (index > 0) 
        ImageName = ImageName.Substring(0, index); 


       MyLog.Add("image name = " + ImageName); 


       string[] textArray1 = new string[] { servicewTMURI, "/Queue/SetFile/", application, "/", queueID, "/" + ImageName + "/xml" }; 
       string requestUriString = string.Concat(textArray1); 

       Guid guid = new Guid(); 
       string boundary = "---------------------------" + guid; 



       httpWebRequest2 = (HttpWebRequest)WebRequest.Create(requestUriString); 
       httpWebRequest2.ContentType = "multipart/form-data; boundary=" + 
       boundary; 
       MyLog.Add("ContentType = " + httpWebRequest2.ContentType); 

       httpWebRequest2.Method = "POST"; 
       httpWebRequest2.KeepAlive = false; 
       httpWebRequest2.Timeout = 5000; 
       httpWebRequest2.Proxy = null; 

       httpWebRequest2.ServicePoint.ConnectionLeaseTimeout = 5000; 
       httpWebRequest2.ServicePoint.MaxIdleTime = 5000; 

       httpWebRequest2.Credentials = 
       System.Net.CredentialCache.DefaultCredentials; 


       using (Stream memStream = new System.IO.MemoryStream()) 
       { 


        byte[] boundarybytes = System.Text.Encoding.ASCII.GetBytes("\r\n--" + 
        boundary + "\r\n"); 


        string formdataTemplate = "\r\n--" + boundary + 
        "\r\nContent-Disposition: form-data; name=\"{0}\";\r\n\r\n{1}"; 






        memStream.Write(boundarybytes, 0, boundarybytes.Length); 

        string headerTemplate = "Content-Disposition: form-data; name=\"{0}\"; filename=\"{1}\"\r\n Content-Type: application/octet-stream\r\n\r\n"; 

        //for (int i = 0; i < files.Length; i++) 
        //{ 

        //MyLog.Add("file = " + files[i]); 
        string header = string.Format(headerTemplate, "uplTheFile", listOfFiles[i]); 

        byte[] headerbytes = System.Text.Encoding.UTF8.GetBytes(header); 

        memStream.Write(headerbytes, 0, headerbytes.Length); 

        using (FileStream fileStream = new FileStream(listOfFiles[i], FileMode.Open, FileAccess.Read)) 
        { 
         byte[] buffer = new byte[1024]; 

         int bytesRead = 0; 

         while ((bytesRead = fileStream.Read(buffer, 0, buffer.Length)) != 0) 
         { 
          memStream.Write(buffer, 0, bytesRead); 

         } 


         memStream.Write(boundarybytes, 0, boundarybytes.Length); 


         fileStream.Close(); 
        } 

        httpWebRequest2.ContentLength = memStream.Length;

       } 


      }

       } 
       catch (Exception exception2) 
       { 
        throw exception2; 
       } 

      } 




     }

Sie diese Dateien hochladen können mehrteilige Formulardaten verwenden, wenn dies ist, zeigen nicht funktioniert, wie Sie den Dienst implementiert haben Empfang der Datei

public void Upload(string uri, string filePath) 
{ 
    string formdataTemplate = "Content-Disposition: form-data; filename=\"{0}\";\r\nContent-Type: image/jpeg\r\n\r\n"; 
    string boundary = "---------------------------" + DateTime.Now.Ticks.ToString("x"); 
    byte[] boundarybytes = Encoding.ASCII.GetBytes("\r\n--" + boundary + "\r\n"); 

    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri); 
    request.ServicePoint.Expect100Continue = false; 
    request.Method = "POST"; 
    request.ContentType = "multipart/form-data; boundary=" + boundary; 

    using(FileStream fileStream = new FileStream(filePath, FileMode.Open, FileAccess.Read, FileShare.Read)) 
    { 
     using (Stream requestStream = request.GetRequestStream()) 
     { 
      requestStream.Write(boundarybytes, 0, boundarybytes.Length); 
      string formitem = string.Format(formdataTemplate, Path.GetFileName(filePath)); 
      byte[] formbytes = Encoding.UTF8.GetBytes(formitem); 
      requestStream.Write(formbytes, 0, formbytes.Length); 
      byte[] buffer = new byte[1024 * 4]; 
      int bytesLeft = 0; 

      while ((bytesLeft = fileStream.Read(buffer, 0, buffer.Length)) > 0) 
      { 
       requestStream.Write(buffer, 0, bytesLeft); 
      } 

     } 
    } 

    try 
    {   
     using (HttpWebResponse response = (HttpWebResponse)request.GetResponse()) { } 

     Console.WriteLine ("Success"); 
    } 
    catch (Exception ex) 
    { 
     throw; 
    } 
}
