如何使异步服务调用同步调用 [英] How make Async service calls into Sync calls

问题描述

我添加服务作为服务参考。然后是Async部分显示的方法。例如，我创建了userAuthentication方法，但它显示为  userAuthenticationAsync。我怎么需要以同步的方式使用这种方法。

i验证用户为 

public bool ValidateUser（string userName，string passWord）

        {

            AuthService.AuthServicesPortTypeClient oAuthClient = new AuthService.AuthServicesPortTypeClient（）;

            oUserAuth = new AuthService.UserAuth（）;

            oUserAuth.userName = userName;

            oUserAuth.password = passWord;

            oUserAuth.EMInumber = StaticDetails.getEMINumber（）;

  &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; oAuthClient.userAuthenticationCompleted + = new EventHandler< AuthService.userAuthenticationCompletedEventArgs>（oAuthClient_userAuthenticationCompleted）;

  oAuthClient.userAuthenticationAsync（oUserAuth）;



  &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; return retBoolValidateUser;

  &NBSP; &NBSP; &NBSP; }

此处    oAuthClient.userAuthenticationAsync（oUserAuth）;
方法在完成上述事件调用之前调用。我需要一个接一个地做..

请给我你的建议......

  &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP; &NBSP;  

解决方案

按照以下链接中所述尝试TaskCompletionSource

i added services as service reference. then the methods that displayed with Async part. as a example, i created method as userAuthentication but it display as userAuthenticationAsync. how ever i need to work this method in Sync way.

i Validated user as 

public bool ValidateUser(string userName,string passWord)
        {
            AuthService.AuthServicesPortTypeClient oAuthClient = new AuthService.AuthServicesPortTypeClient();
            oUserAuth = new AuthService.UserAuth();
            oUserAuth.userName = userName;
            oUserAuth.password = passWord;
            oUserAuth.EMInumber = StaticDetails.getEMINumber();
            oAuthClient.userAuthenticationCompleted += new EventHandler<AuthService.userAuthenticationCompletedEventArgs>(oAuthClient_userAuthenticationCompleted);
  oAuthClient.userAuthenticationAsync(oUserAuth);

            return retBoolValidateUser;
        }

here  oAuthClient.userAuthenticationAsync(oUserAuth); method called before finish the above event calling. I need to do one after another..

Please give me your suggestions...
