嗨，我有以下代码，并试图调用xignite中的一些历史数据。在这种情况下，xyz库是一个xignite库。使用异步方法调用Xignite
//fire an event GetHistoricalQuotesAsOfCompleted
proxy.GetHistoricalQuotesAsOfCompleted +=
new EventHandler<GetHistoricalQuotesAsOfCompletedEventArgs>(GetHistoricalQuotesAsOfCompleted);
//asynchronously request quotes for a time period
proxy.GetHistoricalQuotesAsOfAsync(ticker, xyz.IdentifierTypes.Symbol,
DateTime.Now.ToString(), PeriodTypes.Day, days);
这里是
