[英]SoapHttpClientProtocol: A blocking operation was interrupted by a call to WSACancelBlockingCall
[英]How to perform the operation in 1 blocking call?
如何将这2个操作变成1个操作? 实际上我在后台代理中使用过,但是第二个操作无法执行,并且无法获取该值。 任何想法?
public void running()
{
ServiceReference1.WebServiceSoapClient test = new ServiceReference1.WebServiceSoapClient();
test.ReadTotalOutstandingInvoiceCompleted += new EventHandler<ServiceReference1.ReadTotalOutstandingInvoiceCompletedEventArgs>(serviceClient);
test.ReadTotalOutstandingInvoiceAsync();
}
public void serviceClient(object sender, ReadTotalOutstandingInvoiceCompletedEventArgs e)
{
answer = int.parse(e.Result.ToString());
}
更新:在后台代理中:
VibrateController testVibrateControl = VibrateController.Default;
public int answer;
protected override void OnInvoke(ScheduledTask task)
{
//TODO: Add code to perform your task in background
running();
ShellTile t = ShellTile.ActiveTiles.First();
StandardTileData d = new StandardTileData()
{
Title = "U have " + answer + " Invoice!!",
BackTitle = "How Are You!!",
//Count = 0,
// BackBackgroundImage = new Uri("dog.jpg", UriKind.Relative),
// BackgroundImage = new Uri("untitled.png", UriKind.Relative)
};
t.Update(d);
testVibrateControl.Start(TimeSpan.FromSeconds(3));
testVibrateControl.Stop();
//ShellTile.Create(new Uri("/MainPage.xaml?pp=cas", UriKind.Relative), d);
NotifyComplete();
}
在主页中:
private void CheckBox_Checked_1(object sender, RoutedEventArgs e)
{
try
{
PeriodicTask p = new PeriodicTask("jj");
p.Description = "Don't push the red button";
ScheduledActionService.Add(p);
//ScheduledActionService.LaunchForTest(p.Name, TimeSpan.FromSeconds(2));
#if (DEBUG_AGENT)
ScheduledActionService.LaunchForTest(p.Name, TimeSpan.FromSeconds(2));
#endif
}
catch (Exception ex)
{
}
}
在99.9%的情况下,将异步调用转换为阻塞调用是个坏主意,因此我很想知道您为什么需要这么做。
如果从不执行第二项操作,则可能存在服务器端或连接问题。 假定您正在使用WCF服务,请使用WCF测试客户端检查返回的结果是否符合您的预期。
据我所知, NotifyComplete
是在触发回调之前调用的,这很可能是问题所在。 当所有其他呼叫都通过时,存在潜在的竞争状况,其中回调的速度不够快,无法在将代理执行完成信号通知操作系统之前触发。
您可以做的是在内部包装回调。 像这样:
ServiceReference1.WebServiceSoapClient test = new ServiceReference1.WebServiceSoapClient();
test.ReadTotalOutstandingInvoiceCompleted += (s,e) =>
{
// Do some things here
NotifyComplete();
};
test.ReadTotalOutstandingInvoiceAsync();
从那里继续前进,为什么不让它返回一个int
开头,这样您就不必解析它了?
