如何获得撤单被拒绝的信息？

使用保留字（Reserve Word）不能获得撤单被拒绝的信息提示。 国信OrderTicket发送委托后获得该Order对象，可以通过Order.Cancel()方法撤单，如果撤单被拒绝，那么会触发orderUpdated事件，但是Order的State不会变化，可以通过查看order.StateDetail 查看是否撤单失败。

示例1:使用OrderUpdatedEventArgs 获得撤单被拒绝的提示

using guosen;
using elsystem;
using tsdata.common;
using tsdata.marketdata;

vars:
    guosen.OrderTicket otk1(null),
    guosen.Order ord(null), 
    string accID("410038122059");

method void AnalysisTechnique_Initialized( elsystem.Object sender, elsystem.InitializedEventArgs args ) 
begin
    otk1 = new guosen.OrderTicket;  
    otk1.Symbol = "000002.SZ";
    otk1.Quantity = 12100;
    otk1.Account = accID;
    otk1.Action = OrderAction.Buy;
    otk1.SymbolType = tsdata.common.SecurityType.Stock;
    otk1.Type = tsdata.trading.OrderType.Limit;
    otk1.Duration="GFD";
    otk1.LimitPrice = 26.28;
    ord = otk1.Send();//发单
    ord.Updated += ord_Updated;
    ord.Cancel();//撤单
end;

Method void ord_Updated(elsystem.Object sender,guosen.OrderUpdatedEventArgs args)
Begin
    print(DateTime.Now.ToString()+ "," +
    args.OrderID.ToString()+","+
    args.State.ToString()+","+ 
    args.Order.StateDetail.ToString()+","+
    args.Message);
End;
