.NET Remoting 入门实例

1.创建服务端Class：ProxyServerRemoting
1 using System;
2 using System.Collections.Generic;
3 using System.Text;
4 using Inscription.Manadal.EmrPlugIn.NetMessage;
5 using NLog;
6 using Inscription.Manadal.EmrPlugIn;
7 using System.ComponentModel;
8 using System.Runtime.Remoting;
9 using System.Runtime.Remoting.Channels.Tcp;
10 using System.Runtime.Remoting.Channels;
11
12 namespace Inscription.Mandala.EmrPlugIn.ProxyServer
13 {
14 public class ProxyServerRemoting
15 {
16 // 监听端口
17 private static int port;
18 // 单例对象
19 private static ProxyServerRemoting Instance = null;
20 // 后台工作线程对象
21 private BackgroundWorker backWork = null;
22 //定义服务端监听信道
23 private static TcpServerChannel tcpServerChannel = null;
24
25 private ProxyServerRemoting()
26 {
27 //创建后台工作对象（线程）
28 backWork = new BackgroundWorker();
29 //绑定DoWork事件程序
30 backWork.DoWork += new DoWorkEventHandler(backWork_DoWork);
31 //开始执行后台操作
32 backWork.RunWorkerAsync();
33 }
34
35 ///
36 /// 后台线程
37 ///
38 ///
39 ///
40 private void backWork_DoWork(object sender, DoWorkEventArgs e)
41 {
42 StartServer();
43 }
44
45 ///
46 /// 单例实现
47 ///
48 ///
49 public static ProxyServerRemoting getInstance(int Port)
50 {
51 if (Instance == null)
52 {
53 Instance = new ProxyServerRemoting();
54 tcpServerChannel = new TcpServerChannel(port);
55 port = Port;
56 }
57 return Instance;
58 }
59
60 ///
61 /// 启动服务
62 ///
63 public void StartServer()
64 {
65 ChannelServices.RegisterChannel(tcpServerChannel, false);
66
67 RemotingConfiguration.RegisterWellKnownServiceType(typeof(epiManagerV2), "GetEmrPlugInFunctionV3", WellKnownObjectMode.Singleton);
68 }
69
70 ///
71 /// 停止服务
72 ///
73 public void StopServer()
74 {
75 ChannelServices.UnregisterChannel(tcpServerChannel);
76 }
77 }
78 }
2.创建客户端调用Class：ProxyClient
客户端每次调用完成以后，需要注销掉当前信道，ChannelServices.UnregisterChannel(tcpChannel);
不然会发生异常：信道tcp已注册
using System;
using System.Collections.Generic;
using System.Text;
using NLog;
using System.Runtime.Remoting.Channels.Tcp;
using System.Diagnostics;
using System.Configuration;
using System.Reflection;
using System.Runtime.Remoting.Channels;
using Inscription.Manadal.EmrPlugIn;
namespace Inscription.Mandala.EmrPlugIn.ProxyClient
{
public static class ProxyClient
{
///
/// 获取基于函数的外部接口
///
///
///
///
///
///
public static string GetEmrPlugInFunctionV3(string MainName, string ConfigInfo, string strWorker, string strPatientIndex, string CommandKey, string strParamLst)
{
TcpChannel tcpChannel = null;
Logger logger = NLogManagerV2.GetLogger("GetEmrPlugInFunctionV3_Client");
try
{
logger.Trace("判断服务端进程是否存在");
string strAppName = "IMPIProxyServer";
Process[] curProcesses = Process.GetProcesses();
bool isExist = false;
foreach (Process p in curProcesses)
{
if (p.ProcessName == strAppName)
{
isExist = true;
logger.Trace("服务端进程存在");
break;
}
}
if (isExist == false)
{
logger.Trace("服务端进程不存在");
Process.Start(strAppName);
logger.Trace("重新启动服务端进程");
}
//int port = 3399;
string ip = ConfigurationManager.AppSettings["ServerIP"];
int port = Convert.ToInt32(ConfigurationManager.AppSettings["ServerPort"]);
logger.Trace("监听IP：" + ip + " 监听端口" + port);
//使用TCP通道得到远程对象
tcpChannel = new TcpChannel();
ChannelServices.RegisterChannel(tcpChannel, false);
IepiManagerV2 manager = (IepiManagerV2)Activator.GetObject(typeof(IepiManagerV2), string.Format("tcp://{0}:{1}/GetEmrPlugInFunctionV3", ip, port));
logger.Trace("取得.Net Remoting对象成功");
string strReturn = manager.GetEmrPlugInFunctionV3(MainName, ConfigInfo, strWorker, strPatientIndex, CommandKey, strParamLst);
logger.Trace("客户端调用结束");
return strReturn;
}
catch (Exception ex)
{
logger.Trace(ex.Message);
return string.Empty;
}
finally
{
ChannelServices.UnregisterChannel(tcpChannel);
}
}
}
}
3.业务类：epiManagerV2
业务类实现了IepiManagerV2接口，其中客户端也链接引用了IepiManagerV2接口文件，这样客户端就摆脱了对具体业务Dll的依赖，
客户端编译成一个单独的dll可被第三方程序调用。
public class epiManagerV2 : MarshalByRefObject,IepiManagerV2
{
///
/// 获取基于函数的外部接口
///
///
///
///
///
///
public string GetEmrPlugInFunctionV3(string MainName, string ConfigInfo, string strWorker, string strPatientIndex, string CommandKey, string strParamLst)
{
实现略
}
}
IepiManagerV2接口类
using System;
namespace Inscription.Manadal.EmrPlugIn
{
interface IepiManagerV2
{
string GetEmrPlugInFunctionV3(string MainName, string ConfigInfo, string strWorker, string strPatientIndex, string CommandKey, string strParamLst);
}
}
4.服务端管理工具
实现启动服务，暂停服务，开机自动运行功能
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Net.Sockets;
using System.Threading;
using System.Configuration;
using Microsoft.Win32;
using System.IO;
namespace Inscription.Mandala.EmrPlugIn.ProxyServer
{
public partial class frmMainServer : Form
{
private ProxyServerRemoting Instance = null;
string ip = "127.0.0.1";
int port = 3399;
public frmMainServer()
{
InitializeComponent();
}
///
/// 初始化
///
///
///
private void frmMain_Load(object sender, EventArgs e)
{
InitForm();
StartServer();
}
private void InitForm()
{
this.ip = ConfigurationManager.AppSettings["ServerIp"];
this.port = Convert.ToInt32(ConfigurationManager.AppSettings["ServerPort"]);
}
///
/// 打开服务端
///
private void StartServer()
{
try
{
Instance = ProxyServerRemoting.getInstance(port);
Instance.StartServer();
btnStart.Enabled = false;
btnStop.Enabled = true;
lblStatus.Text = "服务正在运行";
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
}
///
/// 关闭服务
///
private void StopServer()
{
try
{
Instance.StopServer();
btnStart.Enabled = true;
btnStop.Enabled = false;
lblStatus.Text = "服务已关闭";
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
///
/// 窗口显示
///
///
///
private void frmMainServer_Shown(object sender, EventArgs e)
{
this.Hide();
}
///
/// 启动
///
///
///
private void btnStart_Click(object sender, System.EventArgs e)
{
StartServer();
}
///
/// 暂停服务器
///
///
///
private void tsbStop_Click(object sender, EventArgs e)
{
StopServer();
}
///
/// 关闭
///
///
///
private void frmMainServer_FormClosing(object sender, System.ComponentModel.CancelEventArgs e)
{
Instance.StopServer();
}
///
/// 菜单命令
///
///
///
private void contextMenuStrip1_ItemClicked(object sender, ToolStripItemClickedEventArgs e)
{
switch (e.ClickedItem.Text)
{
case "打开":
this.Show();
break;
case "隐藏":
this.Hide();
break;
case "关闭":
Instance.StopServer();
this.Close();
break;
}
}
///
/// 工具栏事件
///
///
///
private void toolStrip1_ItemClicked(object sender, ToolStripItemClickedEventArgs e)
{
switch (e.ClickedItem.Name)
{
case "tsbAutoRun":
SetAutoRun(Core.App.fullPath, true);
break;
case "tsbAutoRunCancel":
SetAutoRun(Core.App.fullPath, false);
break;
}
}
private void notifyIcon1_DoubleClick(object sender, EventArgs e)
{
this.Show();
}
///
/// 设置应用程序开机自动运行
///
/// 应用程序的文件名
/// 是否自动运行，为false时，取消自动运行
/// 设置不成功时抛出异常
private static void SetAutoRun(string fileName, bool isAutoRun)
{
RegistryKey reg = null;
try
{
String name = fileName.Substring(fileName.LastIndexOf(@"\") + 1);
reg = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Run", true);
if (reg == null)
reg = Registry.LocalMachine.CreateSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion\Run");
if (isAutoRun)
reg.SetValue(name, fileName);
else
reg.SetValue(name, false);
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
finally
{
if (reg != null)
reg.Close();
}
}
public static void Test()
{
frmMainServer f = new frmMainServer();
f.Show();
}
}
}
