使用http请求将图像发送到WCF服务

Question

我正在尝试使用来自简单控制台应用程序的http请求向wcf服务发送字节数组

这是我的代码：

*的接口：

[OperationContract]
    [WebInvoke(Method = "POST", UriTemplate = "uploadImage")]
    void UploadImage(byte[] recImg);

• wcf service

  public void UploadImage(byte[] recImg)
  {
      try
      {
          if (recImg != null && recImg.Length != 0)
          {
              MemoryStream memStream = new MemoryStream(recImg, 0, recImg.Length);
              Image img = Image.FromStream(memStream);
              img.Save(@"img.jpg");
          }
      }
      catch (Exception ex)
      {
          Debug.Assert(false, ex.Message);
      }
  }
  

这是控制台应用程序代码：

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("`    http://localhost:3765/ImageService.svc/uploadImage `");
            webRequest.Credentials = CredentialCache.DefaultCredentials;
            webRequest.Method = "POST";
            webRequest.ContentType = "application/octet-stream";
            webRequest.ContentLength = imgBytes.Length;



            Stream dataStream = webRequest.GetRequestStream();
            dataStream.Write(imgBytes, 0, imgBytes.Length);
            dataStream.Close();

            WebResponse response = webRequest.GetResponse();
            dataStream = response.GetResponseStream();

            StreamReader reader = new StreamReader(dataStream);
            string responseFromServer = reader.ReadToEnd();
            reader.Close();
            response.Close();

请帮助我，我不知道这段代码有什么问题...... 它差不多3天了，我不知道如何解决这个问题!!
