Question

I have wpf application that calls wcf service with forms authentication. I added Service Reference to my solution, and in service configuration checked Generate asynchronous operations.

In code behind I created client to that reference, than I attached event to fire after async method is completed, then username and pass is setted:

        client.ClientCredentials.UserName.UserName = txtUser.Text;
        client.ClientCredentials.UserName.Password = passbox.Password;
        client.IsAuthenticatedAsync(txtUser.Text, passbox.Password);
        client.Close();

in IsAuthenticatedCompletedEventArgs I get error: "The communication object, System.ServiceModel.Channels.HttpsChannelFactory+HttpsRequestChannel, cannot be used for communication because it has been Aborted."

是否有任何人知道这种情况发生?

提前感谢!

坦率地说,我没有机会测试你的设想,但这一错误是一个一般性错误,表明在与服务部门沟通时有些错误(这一答案更是评论,但范围很广,可能很合适)。您可以在网站<代码><configuration>栏目中添加以下内容,从而获得更多信息。页: 1

<system.diagnostics>
<trace autoflush="true" />
<sources>
  <source name="System.ServiceModel"
          switchValue="Information, ActivityTracing"
          propagateActivity="true">
    <listeners>
      <add name="sdt"
          type="System.Diagnostics.XmlWriterTraceListener"
          initializeData= "ServiceTestWCFTrace.svclog" />
    </listeners>
  </source>
</sources>

After you get the error use svc log viewer to view the log: C:Program FilesMicrosoft SDKsWindowsv6.0AinSvcTraceViewer.exe There you ll probably find the exact error that caused the Abort on the channel. Hope it helps.
