因为控制台应用程序不能由windows服务提供,因此不要尝试读取或写入到控制台。可以使用windows服务向文件或者事件日志发送跟踪或错误消息。System.Diagnostics.EventLog类提供了对windows事件日志读写的方法。
下面是远程对象使用的程序集: MathLibrary.dll
using System;
using System.Runtime.Remoting;
using System.Diagnostics;
namespace MathLibrary
{
/// <summary>
/// SimpleMath 的摘要说明。
/// </summary>
public class SimpleMath : MarshalByRefObject
{
public SimpleMath()
{
WriteLogEntry("SimpleMath actor called");
}
public int Add(int n1,int n2)
{
WriteLogEntry(string.Format("SimpleMath.Add({0},{1})",n1,n2)); return n1 + n2;
}
public int Subtract(int n1,int n2)
{
WriteLogEntry(string.Format("SimpleMath.Subtract({0},{1})",n1,n2)); return n1 - n2;
}
public void WriteLogEntry(string msg){
EventLog.WriteEntry("MathService",msg);
}
}
}
using System.Runtime.Remoting;
using System.Diagnostics;
namespace MathLibrary
{
/// <summary>
/// SimpleMath 的摘要说明。
/// </summary>
public class SimpleMath : MarshalByRefObject
{
public SimpleMath()
{
WriteLogEntry("SimpleMath actor called");
}
public int Add(int n1,int n2)
{
WriteLogEntry(string.Format("SimpleMath.Add({0},{1})",n1,n2)); return n1 + n2;
}
public int Subtract(int n1,int n2)
{
WriteLogEntry(string.Format("SimpleMath.Subtract({0},{1})",n1,n2)); return n1 - n2;
}
public void WriteLogEntry(string msg){
EventLog.WriteEntry("MathService",msg);
}
}
}
建立windows服务:
新建立一个windows服务项目,命名为 MathService,下面是OnStart()方法中的对远程对象的注册:
protected override void OnStart(string[] args)
{
HttpChannel channel = new HttpChannel(13101);
ChannelServices.RegisterChannel(channel);
RemotingConfiguration.RegisterWellKnownServiceType(typeof(MathLibrary.SimpleMath),"SimpleMath.soap",WellKnownObjectMode.Singleton);
}
{
HttpChannel channel = new HttpChannel(13101);
ChannelServices.RegisterChannel(channel);
RemotingConfiguration.RegisterWellKnownServiceType(typeof(MathLibrary.SimpleMath),"SimpleMath.soap",WellKnownObjectMode.Singleton);
}
通过Installutil.exe可以安装或卸载windows服务。
Installutil directory\MathService.exe //安装
Installutil directory\MathService.exe //卸载
Installutil directory\MathService.exe //卸载
启动windows服务后,可以利用下面的客户端测试,同时,可以在事件查看器中查看相应的消息。
客户端程序:
using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Http;
using System;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Http;
using MathLibrary;
namespace MathClient
{
/// <summary>
/// ClientMain 的摘要说明。
/// </summary>
class ClientMain
{
/// <summary>
/// 应用程序的主入口点。
/// </summary>
[STAThread]
static void Main(string[] args)
{
HttpChannel channel = new HttpChannel();
ChannelServices.RegisterChannel(channel);
namespace MathClient
{
/// <summary>
/// ClientMain 的摘要说明。
/// </summary>
class ClientMain
{
/// <summary>
/// 应用程序的主入口点。
/// </summary>
[STAThread]
static void Main(string[] args)
{
HttpChannel channel = new HttpChannel();
ChannelServices.RegisterChannel(channel);
object remoteObj = Activator.GetObject(typeof(MathLibrary.SimpleMath),"
[url]http://localhost:13101/SimpleMath.soap[/url]");
SimpleMath math = (SimpleMath)remoteObj;
SimpleMath math = (SimpleMath)remoteObj;
do{
Console.WriteLine(" 5 + 2 = {0}",math.Add(5,2));
Console.WriteLine(" 5 - 2 = {0}",math.Subtract(5,2));
}while(Console.ReadLine() != "q");
Console.WriteLine(" 5 + 2 = {0}",math.Add(5,2));
Console.WriteLine(" 5 - 2 = {0}",math.Subtract(5,2));
}while(Console.ReadLine() != "q");
Console.WriteLine("Press Enter to end");
Console.ReadLine();
}
}
}
Console.ReadLine();
}
}
}
