利用WCF的双工通讯实现一个简单的心跳监控系统
何为心跳监控系统？
故名思义，就是监控某个或某些个程序的运行状态，就好比医院里面的心跳监视仪一样，能够随时显示病人的心跳情况。
心跳监控的目的是什么？
与医院里面的心跳监视仪目的类似，监控程序运行状态，一旦出现问题（比如：一些自动运行的服务、程序等突然停止运行了），那么心跳监控系统就能“感知到”并及时的显示在监控界面上，同时可以通过微信、短信告之相关的人员，以便他们及时处理程序异常，从而避免一些自动运行的服务、程序等突然停止运行而造成的一系列损失
心跳监控系统实现的思路是怎样的？
核心技术：WCF的双工通讯
实现步骤：
1.定义WCF的服务契约接口以及回调接口，服务方法主要包括：Start（被监控的程序启动时调用，即通知监控系统，我已经启动了）、Stop（被监控的程序停止时调用，即通知监控系统，我已经停止了）、ReportRunning（被监控的程序运行中定时调用，即通知监控系统，我是正常的并在运行中，同时还起到检测监控系统是否在运行的一个功能，一举两得），回调服务方法应有：Listen（这个是给监控系统主动去定时回调被监控的程序（心跳），如果被监控的程序能正常的返回状态，那么就是正常的，否则有可能已经“死了”，这时监控系统就需要按照预设指令作出相应的操作，比如：监控主界面显示异常的程序，同时发送异常通知消息给相关人员）
2.建立一个心跳监控系统Winform项目，并实现WCF服务，即集成实现WCF服务宿主程序，同时每一个WCF服务方法均需关联界面，即：程序启动了、停止了、运行中均会在界面实时显示出来或做一些实时统计；
3.其它被监控的程序（指自动运行的服务、程序等）需要集成实现WCF回调接口及开启WCF服务通讯的功能；
心跳监控系统的运行顺序是怎样的？如何保证监控方与被监控方实时不间断通讯？
运行顺序：
1.开启心跳监控系统（即：同时开启WCF服务宿主程序），确保监控服务正常运行；
2.开启其它被监控的程序，确保开启客户端与监控系统的WCF双工通讯服务正常；
注意：一定要先开启心跳监控系统，否则其它被监控的程序因无法与监控系统的WCF双工通讯服务正常连接而报错或多次尝试重连；
保证监控方与被监控方实时不间断通讯：
在保证按照上面所说的运行顺序依次开启心跳监控系统，再开启其它被监控的程序，正常建立一次通讯后，后续只要任何一方出现通讯中断，均会自动尝试重连（主要是客户端重连，心跳监控系统除非停止运行，否则不会中断，若因停止运行造成双方通讯中断，只需重启心跳监控系统即可）
通讯模式：
推模式：被监控的程序通过主动的调用WCF服务方法：Start、Stop、ReportRunning 向心跳监控系统告之运行状态，若通讯失败，则自动尝试重连，直至连接成功；
拉模式：心跳监控系统主动回调Listen方法，向被监控的程序索取运行状态，若通讯失败，则会在指定时间内多次重试回调客户端，若客户端在规定的时间范围内仍无法返回消息，则视为客户端异常，那么心跳监控系统则会进行异常的处理；
实现源代码：
ProgramMonitor.Core 类库项目：主要是定义WCF服务的相关接口以及实现回调的接口（因为每个客户端都需实现一遍回调接口，故统一实现，客户端集成后直接可以用，简化集成客户端的开发成本），心跳监控系统及需要被监控的程序均需要依赖该DLL；
ProgramMonitor WINFORM项目：心跳监控系统
整个解决方案如下图示：

hashData = md5.ComputeHash(fs);
fs.Close();
}
StringBuilder sb = new StringBuilder();
for (int i = 0; i < hashData.Length; i++)
{
sb.Append(hashData[i].ToString("x2"));
}
return sb.ToString();
}
catch (Exception ex)
{
throw new Exception("GetMD5HashFromFile Error:" + ex.Message);
}
}
}
}
这里特别说一下：CreateProgramId方法，因为心跳监控系统主要是依据ProgramId来识别每个不同的程序，故ProgramId非常重要，而我这里采用的是文件的 MD5值+进程数作为ProgramId，有些人可能要问，为什么要加进程数呢？原因很简单，因为有些程序是允许开启多个的实例的，如果不加进程数，那么心跳监控系统就无法识别多个同一个程序到底是哪个。

被监控的客户端程序集成WCF监听客户端很简单，只需引用ProgramMonitor.Core，然后实例化ListenClient，最后就可以通过该ListenClient与心跳监控系统进行双工通讯，在此就不贴出源代码了。
上述代码中还有用到两个类：
DataAccess：数据访问类，这个我之前的文章有介绍，详见：DataAccess通用数据库访问类，简单易用，功能强悍
WeChat：微信企业号发送消息类，注意是微信企业号，不是公众号，这里我也贴出源代码来，供大家了解：
