c# - 计划任务代理 wp7 soap 客户端不工作

Question

我有这个：

public class ScheduledAgent : ScheduledTaskAgent
{
    ...

    protected override void OnInvoke(ScheduledTask task)
    {
        var userSettings = Utils.LoadSettings();
        try
        {
            var client = new CheckinServiceSoapClient();
            var token = WsApiCaller.Token;
            var point = ... // User Location;
            if (point != null)
            {
                client.UserTrackAsync(token, userSettings.UserId, 
                    point.Latitude, point.Longitude, 
                    point.Position.Location.HorizontalAccuracy,
                    point.Position.Location.Altitude,
                    point.Position.Location.Speed,
                    point.Position.Location.VerticalAccuracy,
                    point.Position.Location.Course,
                    "BACKGROUND_AGENT");
            }
        }
        catch
        {
        }
        NotifyComplete();
    }
}   

OnInvoke 事件发生。但是没有执行 UserTrackAsync 的调用。

Answer 1

你client.UserTrackAsync是一个异步调用。问题是在有机会完成NotifyComplete();之前执行。client.UserTrackAsync

您需要在UserTrackCompleted处理程序中调用它（并从原始位置删除它）：

client.UserTrackCompleted += (sender, args) => 
{ 
    var res = args.Result.Retval; 
    NotifyComplete();
};
