Question

我已经从outlook创建了一个控制台电子邮件应用程序读取应用程序每当新邮件到达收件箱时，都会调用异步方法。此异步方法通过发送Web请求来调用Web服务并在服务内部执行该功能。这些应用程序像调度程序作业一样运行。当第一封电子邮件进入收件箱时，这个过程正在运行。在第二个它有异常异常：交易范围嵌套错误。当我尝试关闭电子邮件应用程序然后开始，那时它的工作正常。我该如何解决这个异常？ 以下是来自电子邮件应用程序的致电服务代码

static void Save(string userAlias, string engagementName, string documentTranferId, string fileName, string fileSize,string activityName)
        {
            try
            {
                userAlias = userAlias.ToLower();
                var url = new StringBuilder();
                url.Append(
               string.Format("https://myapp.com:8443/Services/MyService/Test.svc/Save?User={0}&Engagement={1}&FileName={2}&DocumentTrasferID={3}&fileSize={4}&ActivityName={5}",userAlias, engagementName, fileName, documentTranferId, fileSize, activityName));
                Console.WriteLine(url);
                WebRequest request = WebRequest.Create(url.ToString());
                CurrentUrl = url.ToString();
                var networkCredential = new NetworkCredential("testr", "123Test", "jemi");
                request.Credentials = networkCredential;
                WebResponse response = request.GetResponse();
                Encoding encoding = Encoding.GetEncoding(1252);
                var responseStream = new StreamReader(response.GetResponseStream());
                string responseResult = responseStream.ReadToEnd();
                responseStream.Close();
                Console.WriteLine(responseResult);
            }
            catch(Exception ee)
            {
                Console.WriteLine(ee.Message);
            }

        }

服务详情 - 端点

 <OperationContract()> _
  <WebGet(UriTemplate:="/Save?User={User}&Engagement={Engagement}&FileName={FileName}&DocumentTrasferID={documentTrasferID}&fileSize={fileSize}&ActivityName={ActivityName}", RequestFormat:=WebMessageFormat.Json, ResponseFormat:=WebMessageFormat.Json)> _
    Function Save(ByVal User As String, ByVal Engagement As String, ByVal FileName As String, ByVal DocumentTrasferID As String, ByVal fileSize As String, ByVal ActivityName As String) As String

实施

Public Function Save(ByVal User As String, ByVal Engagement As String, ByVal FileName As String, ByVal DocumentTrasferID As String, ByVal fileSize As String, ByVal ActivityName As String) As String Implements IMyInterface.Save
        Dim facade= New MyFacade
        Dim Result As String = facade.Save(User, Engagement, FileName, DocumentTrasferID, fileSize, ActivityName)
        Return Result
    End Function

门面类。这是我得到了例外

Public Function Save(Doc doc,string id,string param) As String
Dim facade= New MyFacade
facade.Save(doc, id, param)
End Function

例外：交易范围嵌套不正确
