Question

请帮助我，

我需要在OnTickHistoryResponse事件的形式中使用，所以当事件发生时我可以在控件中显示信息。

事件OnTickHistoryResponse附带一个名为ActivetickFeed的API，此事件OnTickHistoryResponse已经在API中，请您帮忙，我不知道如何使用该事件。

仅在文档中显示：Image

定义事件并为其分配方法的类是：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ActiveTickFeedCOMCSExample
{
    class ActiveTickFeed
    {
        public static ActiveTickFeedLib.Feed feed;
        public static ActiveTickFeed instance;

        public ActiveTickFeed()
        {
            //create new instance of IFeed
            feed = new ActiveTickFeedLib.Feed();

            feed.PrimaryServerHostname = "activetick1.activetick.com";
            feed.BackupServerHostname = "activetick2.activetick.com";

            feed.ServerPort = 443;

            //connect all IFeedEvents events to local methods
            
            feed.OnTickHistoryResponse += feed_OnTickHistoryResponse;
            
            }
            
            
            void feed_OnTickHistoryResponse(int originalRequestId, short tickHistoryResponseCode, string symbol, short symbolStatusCode, object records)
        {
            Form1.instance.AddData("Processing OnTickHistoryResponse........");

            Form1.instance.AddData("ATTickHistoryResponseType: " + ((ActiveTickFeedLib.ATTickHistoryResponseEnum)tickHistoryResponseCode).ToString());
            Form1.instance.AddData("ATSymbolStatus: " + ((ActiveTickFeedLib.ATSymbolStatusEnum)symbolStatusCode).ToString());

            switch ((ActiveTickFeedLib.ATTickHistoryResponseEnum)tickHistoryResponseCode)
            {
                case ActiveTickFeedLib.ATTickHistoryResponseEnum.ATTickHistoryResponseSuccess:
                case ActiveTickFeedLib.ATTickHistoryResponseEnum.ATTickHistoryResponseMaxLimitReached:
                    {
                        if ((ActiveTickFeedLib.ATSymbolStatusEnum)symbolStatusCode == ActiveTickFeedLib.ATSymbolStatusEnum.ATSymbolStatusSuccess)
                        {
                            if (records != null)
                            {
                                string[] recordsArray = (string[])records;
                                foreach (string s in recordsArray)
                                    Form1.instance.AddData(s);
                            }
                        }
                    }
                    break;
                case ActiveTickFeedLib.ATTickHistoryResponseEnum.ATTickHistoryResponseInvalidRequest:
                    break;
                case ActiveTickFeedLib.ATTickHistoryResponseEnum.ATTickHistoryResponseDenied:
                    break;
            }
        }

Answer 1

每当您发送“SendTickHistoryRequest”时，作为回复，您将收到“OnTickHistoryResponse”事件。所以事件订阅是不够的，请发送请求（SendTickHistoryRequest），你将得到一个响应事件。
