WPS RTD C#实现例子

以下是 WPS RTD C# 实现的示例代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Office.Interop.Excel;
using Microsoft.Office.Interop.Word;

namespace WPSRTDExample
{
    [ComVisible(true)]
    public class WPSRTD : IRtdServer
    {
        private IRTDUpdateEvent _callback;
        private Dictionary<int, string> _topics = new Dictionary<int, string>();
        private Random _random = new Random();

        public int ServerStart(IRTDUpdateEvent CallbackObject)
        {
            _callback = CallbackObject;
            return 1;
        }

        public void ServerTerminate()
        {
            _callback = null;
        }

        public object ConnectData(int TopicID, ref Array Strings, ref bool GetNewValues)
        {
            if (!_topics.ContainsKey(TopicID))
            {
                _topics.Add(TopicID, Strings.GetValue(0).ToString());
            }

            return _random.Next(100);
        }

        public void DisconnectData(int TopicID)
        {
            if (_topics.ContainsKey(TopicID))
            {
                _topics.Remove(TopicID);
            }
        }

        public int Heartbeat()
        {
            return 1;
        }

        public Array RefreshData(ref int TopicCount)
        {
            if (_callback != null)
            {
                _callback.UpdateNotify();
            }

            TopicCount = _topics.Count;
            return Enumerable.Range(0, TopicCount).Select(i => _random.Next(100)).ToArray();
        }

        public int RefreshData(int TopicID, ref Array NewValues, ref bool GetNewValues)
        {
            NewValues.SetValue(_random.Next(100), 0);
            return 1;
        }

        public object[,] GetLastUpdate(ref int TopicCount)
        {
            TopicCount = _topics.Count;
            return Enumerable.Range(0, TopicCount).Select(i => new object[] { _topics.ElementAt(i).Value, _random.Next(100) }).ToArray();
        }
    }
}

在这个示例中，WPS RTD 服务器会返回一个随机整数，当连接数据时。在刷新数据时，它会向每个主题返回一个新的随机整数。在获取最近更新时，它将返回每个主题的名称和最后一个随机整数。你可以根据你的需求修改这个示例代码。
