消息队列
在这个数组内部，CWorker 类创建了 CWorkerThread类的一个实现版
本。CWorkerThread 类（将在下面讨论）是一个必须继承的抽象类。导出
类定义了消息的处理方式：
aThreads = new ArrayList();
for (int idx=0; idx〈sfWorker.NumberThreads; idx++)
{
WorkerThreadFormatter wfThread = new WorkerThreadFormatter();
wfThread.ProcessName = sfWorker.ProcessName;
wfThread.ProcessDesc = sfWorker.ProcessDesc;
wfThread.ThreadNumber = idx;
wfThread.InputQueue = sfWorker.InputQueue;
wfThread.ErrorQueue = sfWorker.ErrorQueue;
wfThread.OutputName = sfWorker.OutputName;
// 定义辅助类型，并将其插入辅助线程结构
CWorkerThread wtBase;
switch (sfWorker.ProcessType)
{
case WorkerFormatter.SFProcessType.ProcessRoundRobin:
wtBase = new CWorkerThreadRoundRobin(this, wfThread);
break;
case WorkerFormatter.SFProcessType.ProcessAppSpecific:
wtBase = new CWorkerThreadAppSpecific(this, wfThread);
break;
case WorkerFormatter.SFProcessType.ProcessAssembly:
wtBase = new CWorkerThreadAssembly(this, wfThread);
break;
default:
throw new Exception("Unknown Processing Type");
}
// 添加对数组的调用
aThreads.Insert(idx, wtBase);
}
一旦所有的对象都已创建，就可以通过调用每个线程对象的 Start方
法来启动它们：
foreach(CWorkerThread cThread in aThreads)
cThread.Start();
Stop、Pause 和 Continue 方法在 foreach循环里执行的操作类似。
Stop方法具有如下的垃圾收集操作：
GC.SuppressFinalize(this);
在类析构函数中将调用 Stop 方法，这样，在没有显式调用 Stop 方
法的情况下也可以正确地终止对象。如果调用了 Stop 方法，将不需要析
构函数。SuppressFinalize方法能够防止调用对象的 Finalize 方法（析
构函数的实际实现）。
CWorkerThread 抽象类
CWorkerThread 是一个由 CWorkerThreadAppSpecifc、CWorkerThread
RoundRobin 和 CWorkerThreadAssembly继承的抽象类。无论如何处理消
息，队列的大部分处理是相同的，所以 CWorkerThread类提供了这一功能。
这个类提供了抽象方法（必须被实际方法替代）以管理资源和处理消息。
类的工作再一次通过 Start、Stop、Pause 和 Continue 方法来实现。
在 Start方法中引用了输入和错误队列。在 .NET 框架中，消息由 System.
Messaging 名称空间处理：
// 尝试打开队列，并设置默认的读写属性
MessageQueue mqInput = new MessageQueue(sInputQueue);
mqInput.MessageReadPropertyFilter.Body = true;
mqInput.MessageReadPropertyFilter.AppSpecific = true;
MessageQueue mqError = new MessageQueue(sErrorQueue);
// 如果使用 MSMQ COM，则将格式化程序设置为 ActiveX
mqInput.Formatter = new ActiveXMessageFormatter();
mqError.Formatter = new ActiveXMessageFormatter();
一旦定义了消息队列引用，即会创建一个线程用于实际的处理函数
（称为 ProcessMessages）。在 .NET 框架中，使用 System.Threading
名称空间很容易实现线程处理：
procMessage = new Thread(new ThreadStart(ProcessMessages));
procMessage.Start();
ProcessMessages 函数是基于 Boolean值的处理循环。当数值设为
False，处理循环将终止。因此，线程对象的 Stop 方法只设置这一Boolean
值，然后关闭打开的消息队列，并加入带有主线程的线程：
// 加入服务线程和处理线程
bRun = false;
procMessage.Join();
// 关闭打开的消息队列
mqInput.Close();
mqError.Close();
Pause 方法只设置一个 Boolean 值，使处理线程休眠半秒钟：
if (bPause)
Thread.Sleep(500);
最后，每一个 Start、Stop、Pause 和 Continue 方法将调用抽象的
OnStart 、OnStop、OnPause 和 OnContinue 方法。这些抽象方法为实现
的类提供了挂钩，以捕获和释放所需的资源。
ProcessMessages 循环具有如下基本结构：
●接收Message。
●如果Message具有成功的Receive，则调用抽象ProcessMessage方法。
●如果Receive或ProcessMessage失败，将Message发送至错误队列中。
Message mInput;
try
{
// 从队列中读取，并等候 1 秒
mInput = mqInput.Receive(new TimeSpan(0,0,0,1));
}
catch (MessageQueueException mqe)
{
// 将消息设置为 null
mInput = null;
// 查看错误代码，了解是否超时
if (mqe.ErrorCode != (-1072824293) ) //0xC00E001B
{
// 如果未超时，发出一个错误并记录错误号
LogError("Error: " + mqe.Message);
throw mqe;
}
}
if (mInput != null)
{
// 得到一个要处理的消息，调用处理消息抽象方法
try
{
ProcessMessage(mInput);
}
// 捕获已知异常状态的错误
catch (CWorkerThreadException ex)
{
ProcessError(mInput, ex.Terminate);
}
// 捕获未知异常，并调用 Terminate
catch
{
ProcessError(mInput, true);
}
}
ProcessError方法将错误的消息发送至错误队列。另外，它也可能引
发异常来终止线程。如果ProcessMessage方法引发了终止错误或 CWorker
ThreadException类型，它将执行此操作。
CworkerThread 导出类
任何从 CWorkerThread中继承的类都必须提供 OnStart、OnStop、On
Pause、OnContinue和 ProcessMessage 方法。OnStart 和 OnStop方法获
取并释放处理资源。OnPause 和 OnContinue 方法允许临时释放和重新获
取这些资源。ProcessMessage方法应该处理消息，并在出现失败事件时引
发 CWorkerThreadException 异常。
由于 CWorkerThread构造函数定义运行时参数，导出类必须调用基类
构造函数：
public CWorkerThreadDerived(CWorker v_cParent, WorkerThread
Formatter v_wfThread)
: base (v_cParent, v_wfThread) {}
导出类提供了两种类型的处理：将消息发送至另一队列，或者调用组
件方法。接收和发送消息的两种实现使用了循环技术或应用程序偏移（保
留在消息 AppSpecific属性中），作为使用哪一队列的决定因素。此方案
中的配置文件应该包括队列路径的列表。实现的 OnStart和 OnStop 方法
应该打开和关闭对这些队列的引用：
iQueues = wfThread.OutputName.Length;
mqOutput = new MessageQueue[iQueues];
for (int idx=0; idx〈iQueues; idx++)
{
mqOutput[idx] = new MessageQueue(wfThread.OutputName[idx]);
mqOutput[idx].Formatter = new ActiveXMessageFormatter();
}
在这些方案中，消息的处理很简单：将消息发送必要的输出队列。在
循环情况下，这个进程为：
try
{
mqOutput[iNextQueue].Send(v_mInput);
}
catch (Exception ex)
{
// 如果错误强制终止异常
throw new CWorkerThreadException(ex.Message, true);
}
// 计算下一个队列号
iNextQueue++;
iNextQueue %= iQueues;
后一种调用带消息参数的组件的实现方法比较有趣。ProcessMessage
方法使用 IWebMessage接口调入一个 .NET 组件。OnStart 和 OnStop 方
法获取和释放此组件的引用。
此方案中的配置文件应该包含两个项目：完整的类名和类所在文件的
位置。按照 IWebMessage接口中的定义，在组件上调用 Process方法。
要获取对象引用，需要使用 Activator.CreateInstance 方法。此函
数需要一个程序集类型。在这里，它是从程序集文件路径和类名中导出的。
一旦获取对象引用，它将被放入合适的接口：
private IWebMessage iwmSample;
private string sFilePath, sTypeName;
// 保存程序集路径和类型名称
sFilePath = wfThread.OutputName[0];
sTypeName = wfThread.OutputName[1];
// 获取对必要对象的引用
Assembly asmSample = Assembly.LoadFrom(sFilePath);
Type
typSample = asmSample.GetType(sTypeName);
object objSample = Activator.CreateInstance(typSample);
// 定义给对象的必要接口
iwmSample = (IWebMessage)objSample;
获取对象引用后，ProcessMessage方法将在 IWebMessage接口上调用
Process 方法：
WebMessageReturn wbrSample;
try
{
// 定义方法调用的参数
string sLabel = v_mInput.Label;
string sBody = (string)v_mInput.Body;
int iAppSpecific = v_mInput.AppSpecific;
// 调用方法并捕捉返回代码
wbrSample = iwmSample.Process(sLabel, sBody, iAppSpecific);
}
catch (InvalidCastException ex)
{
// 如果在消息内容中发生错误，则强制发出一个非终止异常
throw new CWorkerThreadException(ex.Message, false);
}
catch (Exception ex)
{
// 如果错误调用程序集，则强制发出终止异常
throw new CWorkerThreadException(ex.Message, true);
}
// 如果没有错误，则检查对象调用的返回状态
switch (wbrSample)
{
case WebMessageReturn.ReturnBad:
throw new CWorkerThreadException
("Unable to process message: Message marked bad", false);
case WebMessageReturn.ReturnAbort:
throw new CWorkerThreadException
("Unable to process message: Process terminating", true);
default:
break;
}
提供的示例组件将消息正文写入数据库表。如果捕获到严重数据库错
误，您可能希望终止处理过程，但是在这里，仅仅将消息标记为错误的消
息。
由于此示例中创建的类实例可能会获取并保留昂贵的数据库资源，所
以用 OnPause和 OnContinue 方法释放和重新获取对象引用。
检测设备
就象在所有优秀的应用程序中一样，检测设备用于监测应用程序的状
态。。NET 框架大大简化了将事件日志、性能计数器和 Windows管理检测
设备（WMI ）纳入应用程序的过程。消息应用程序使用时间日志和性能计
数器，二者都是来自 System.Diagnostics 程序集。
在 ServiceBase类中，您可以自动启用事件日志。另外，ServiceBase
EventLog成员支持写入应用程序事件日志：
EventLog.WriteEntry(sMyMessage, EventLogEntryType.Information);
对于写入事件日志而不是应用程序日志的应用程序，它能够很容易地
创建和获取 EventLog 资源的引用（正如在 CWorker类中所做的一样），
并能够使用 WriteEntry 方法记录日志项：
private EventLog cLog;
string sSource = ServiceControl.ServiceControlName;
string sLog = "Application";
// 查看源是否存在，如果不存在，则创建源
if (!EventLog.SourceExists(sSource))
EventLog.Creat
eEventSource(sSource, sLog);
// 创建日志对象，并引用现在定义的源
cLog = new EventLog();
cLog.Source = sSource;
// 在日志中写入条目，表明创建成功
cLog.WriteEntry("已成功创建", EventLogEntryType.Information);
.NET 框架大大简化了性能计数器。对于每一个处理线程、线程导出
的用户和整个应用程序，这一消息应用程序都能提供计数器，用于跟踪消
息数量和每秒钟处理消息的数量。要提供此功能，您需要定义性能计数器
的类别，然后增加相应的计数器实例。
性能计数器的类别在服务 OnStart方法中定义。这些类别代表两种计
数器——消息总数和每秒钟处理的消息数：
CounterCreationData[] cdMessage = new CounterCreationData[2];
cdMessage[0] = new CounterCreationData("Messages/Total", "Total
Messages Processed",
PerformanceCounterType.NumberOfItems64);
cdMessage[1] = new CounterCreationData("Messages/Second",
"Messages Processed a Second",
PerformanceCounterType.RateOfChangePerSecond32);
PerformanceCounterCategory.Create("MSDN Message Service", "MSDN
Message Service Counters", cdMessage);
一旦定义了性能计数器类别，将创建 PerformanceCounter 对象以访
问计数器实例功能。PerformanceCounter对象需要类别、计数器名称和一
个可选的实例名称。对于辅助进程，将使用来自 XML文件的进程名称，代
码如下：
pcMsgTotWorker = new PerformanceCounter("MSDN Message Service",
"Messages/Total", sProcessName);
pcMsgSecWorker = new PerformanceCounter("MSDN Message Service",
"Messages/Second", sProcessName);
pcMsgTotWorker.RawValue = 0;
pcMsgSecWorker.RawValue = 0;
要增加计数器的值，仅仅需要调用适当的方法：
pcMsgTotWorker.IncrementBy(1);
pcMsgSecWorker.IncrementBy(1);
最后说明一点，服务终止时，安装的性能计数器类别应该从系统中删除：
PerformanceCounterCategory.Delete("MSDN Message Service");
由于性能计数器在 .NET 框架中工作，因此需要运行一项特殊的服务。
此服务（PerfCounterService）提供了共享内存。计数器信息将写入共享
内存，并被性能计数器系统读取。
安装
在结束以前，我们来简要介绍一下安装以及称为 installutil.exe的
安装工具。由于此应用程序是 Windows服务，它必须使用installutil.exe
来安装。因此，需要使用一个从 System.Configuration.Install 程序集
中继承的 Installer类：
public class ServiceRegister: Installer
{
private ServiceInstaller serviceInstaller;
private ServiceProcessInstaller processInstaller;
public ServiceRegi
ster()
{
// 创建服务安装程序
serviceInstaller = new ServiceInstaller();
serviceInstaller.StartType = ServiceStart.Manual;
serviceInstaller.ServiceName = ServiceControl.ServiceControl
Name;
serviceInstaller.DisplayName = ServiceControl.ServiceControl
Desc;
Installers.Add(serviceInstaller);
// 创建进程安装程序
processInstaller = new ServiceProcessInstaller();
processInstaller.RunUnderSystemAccount = true;
Installers.Add(processInstaller);
}
}
如此示例类所示，对于一个 Windows服务，服务和服务进程各需要一
个安装程序，以定义运行服务的帐户。其他安装程序允许注册事件日志和
性能计数器等资源。
总结
从这个 .NET 框架应用程序示例中可以看出，以前只有 Visual C++
程序员能够编写的应用程序，现在使用简单的面向对象程序即可实现。尽
管我们的重点是 C# ，但本文所述的内容也同样适用于 Visual Basic 和
Managed C++.新的 .NET 框架使开发人员能够使用任何编程语言来创建功
能强大、可伸缩的 Windows应用程序和服务。
新的 .NET 框架不仅简化和扩展了编程的种种可能，还能够轻松地将
人们经常遗忘的应用程序检测设备（例如性能监测计数器和事件日志通知）
合并到应用程序中。尽管这里的应用程序没有使用 Windows管理检测设备
（WMI ），但 .NET 框架同样也可以应用它。
