我想获得这种方法的结果是：布尔认证（字符串日志，串通），这梅索德：字符串作用（字符串日志，串通）来测试authentifcation 这是我做的：

I want to get the result of this method : bool authentication (string log, string pass) and this methode : string role (string log, string pass) to test authentifcation this is what I did :

private void bntValideAuthen_Click(object sender, RoutedEventArgs e)
{ 
    client.AuthentificationCompleted += client_AuthentificationCompleted;
    client.RoleCompleted += client_RoleCompleted;

      ServiceConsum.Service1Client client = new ServiceConsum.Service1Client();
     string rol=client.RoleAsync(txtLogin.text,txtpass.text);
     bool auth = client.AuthentificationAsync(txtLogin.text,txtpass.text);


    if((auth==true)&&(role=="admin"))
    {
      NavigationContext.Equals(new Uri("/Views/admin/starAdmin.xaml", UriKind.Relative));
    }
    else
    {
      message.BOX("error");
    }

    }

它给这个错误： 无法隐式转换类型'无效'到'字符串'

it gives this error : Can not implicitly convert type 'void' to 'string'

推荐答案

解决方案是： 在第二个事件增加胎面这样的：

Solution is : add a tread in second event like :

 void client_RoleCompleted(object sender, RoleCompletedEventArgs e) { 
            role = e.Result.ToString();
            Thread.Sleep(1000);


        }
