IsOneWay WCF 서비스를 호출하고 클라이언트를 올바르게 호출하는 방법

Question

저는 WCF를 처음 사용하고 테스트 웹 사이트와 서비스를 설치했습니다. 제대로

나는 웹 서비스를 생성하고 그것에게 isoneway 속성을 준 사용자에게

닫기 클라이언트를 차단하지 않고

1. 전화 서비스 : 나는이 두 가지를 달성하려고 해요. 나는 사용자를 차단하지 않고 그것을 호출 할 수 있었지만 나는 클라이언트를 닫지 않을까 걱정된다. 어떻게하면 사용자를 차단하지 않고이 서비스를 호출 할 수 있습니까? 비동기 메서드 (TestServiceAsync)를 사용해야합니까? BeginXX, EndXX 메서드를 사용해야합니까?

   클라이언트 :

   Dim callservice As New WCFEmailServices.EmailServiceClient() 
   callservice.TestService() 
   callservice.Close() 
   

   Webservice를 :

   <ServiceContract()> _ 
       Public Interface IEmailService 
   
   
        <OperationContract(IsOneWay:=True)> _ 
        Sub TestService() 
   
   
       End Interface 
   
   
       Public Class EmailService 
       Implements IEmailService 
   
       Public Sub TestService() Implements IEmailService.TestService 
   
        Dim srvBody As String = "" 
        srvBody = "START: " + DateTime.Now.ToLongTimeString() + System.Environment.NewLine 
        Thread.Sleep(10000) 
        srvBody += "END: " + DateTime.Now.ToLongTimeString() + System.Environment.NewLine 
   
        Me.SendEmail("test@gmail.com", "test", srvBody, Nothing) 
   
       End Sub 
   
   
       Function SendEmail(ByVal srpTo As String, ByVal srpSubject As String, ByVal srpBody As String, ByVal srpAttachmentPath As String) As Boolean 
   
        Dim MailMsg As New MailMessage(New MailAddress("No_Reply@test.com"), New MailAddress(srpTo)) 
        MailMsg.BodyEncoding = Encoding.UTF8 
        MailMsg.Subject = srpSubject 
        MailMsg.Body = srpBody 
        MailMsg.IsBodyHtml = True 
   
        If srpAttachmentPath IsNot Nothing Then 
         Dim srvAttachment As New Attachment(srpAttachmentPath) 
         MailMsg.Attachments.Add(srvAttachment) 
        End If 
   
   
        Dim SmtpMail As New SmtpClient("smtp.gmail.com", 587) 
        SmtpMail.UseDefaultCredentials = False 
        SmtpMail.EnableSsl = True 
        SmtpMail.Credentials = New System.Net.NetworkCredential("No_Reply@test", "password") 
   
        Try 
         SmtpMail.Send(MailMsg) 
        Catch 
         Return False 
        End Try 
        Return True 
       End Function

Answer 1

당신은 제대로 IsOneWay 호출 후 클라이언트를 종료합니다. 바인딩에 따라 IsOneWay가 완료 될 때까지 close()가 차단됩니다. Calling Close() on Service Proxy blocks after One Way WCF call
