设置c#windows服务描述及允许服务与桌面交互的几种方法
方法一：
在ProjectInstaller.cs重写 install() ,Uninstall()方法
public override void Install(IDictionary stateServer) { Microsoft.Win32.RegistryKey system, //HKEY_LOCAL_MACHINE/Services/CurrentControlSet currentControlSet, //.../Services services, //.../<Service Name> service, //.../Parameters - this is where you can put service-specific configuration config; try { //Let the project installer do its job base.Install(stateServer); //Open the HKEY_LOCAL_MACHINE/SYSTEM key system = Microsoft.Win32.Registry.LocalMachine.OpenSubKey("System"); //Open CurrentControlSet currentControlSet = system.OpenSubKey("CurrentControlSet"); //Go to the services key services = currentControlSet.OpenSubKey("Services"); //Open the key for your service, and allow writing service = services.OpenSubKey(this.serviceInstaller1.ServiceName, true); //Add your service's description as a REG_SZ value named "Description" service.SetValue("Description","PI实时数据采集：能源--每天8点或20点取一次数据；汽车衡--每天1点取一次数据；设备状态--每分钟取一次数据。"); //(Optional) Add some custom information your service will use... //允许服务与桌面交互 service.SetValue("Type",0x00000110); config = service.CreateSubKey("Parameters"); } catch(Exception e) { Console.WriteLine("An exception was thrown during service installation:/n" + e.ToString()); } } public override void Uninstall(IDictionary stateServer) { Microsoft.Win32.RegistryKey system, currentControlSet, services, service; try { //Drill down to the service key and open it with write permission system = Microsoft.Win32.Registry.LocalMachine.OpenSubKey("System"); currentControlSet = system.OpenSubKey("CurrentControlSet"); services = currentControlSet.OpenSubKey("Services"); service = services.OpenSubKey(this.serviceInstaller1.ServiceName, true); //Delete any keys you created during installation (or that your service created) service.DeleteSubKeyTree("Parameters"); //... } catch(Exception e) { Console.WriteLine("Exception encountered while uninstalling service:/n" + e.ToString()); } finally { //Let the project installer do its job base.Uninstall(stateServer); } }
我们写一个服务，有时候要让服务启动某个应用程序，就要修改服务的属性，勾选允许服务与桌面交互，
可以用修改注册表实现，我们必须在安装后操作，所以请重写Installer的OnAfterInstall。
protected override void OnAfterInstall(System.Collections.IDictionary savedState) { RegistryKey rk = Registry.LocalMachine; string key = @"SYSTEM/CurrentControlSet/Services/" + this.sInstaller.ServiceName; RegistryKey sub = rk.OpenSubKey(key, true); int value = (int)sub.GetValue("Type"); if (value < 256) { sub.SetValue("Type", value | 256); } base.OnAfterInstall(savedState); }
onstart的时候修改注册表
[HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/你的服务名]
"Type"=dword:00000010
key value＋256
比如现在00000010是16＋256＝272
16进制就是00000110
ConnectionOptions coOptions = new ConnectionOptions(); coOptions.Impersonation = ImpersonationLevel.Impersonate; ManagementScope mgmtScope = new System.Management.ManagementScope(@"root/CIMV2", coOptions); mgmtScope.Connect(); ManagementObject wmiService; wmiService = new ManagementObject("Win32_Service.Name='" + ServiceController.ServiceName + "'"); ManagementBaseObject InParam = wmiService.GetMethodParameters("Change"); InParam["DesktopInteract"] = true; ManagementBaseObject OutParam = wmiService.InvokeMethod("Change", InParam, null); ServiceController.Start();
描述：在自己写的一个系统服务程序，需要经常用到“允许与桌面进行交互”的设置，网上很多使用修改注册表的形式实现，我测试过，修改注册表后，选中的勾是选上了，
但不能弹出应用程序；据说重启电脑后可以，但我不想重启，实际应用也不允许重启，故没有测试重启是否可行的情况。如图：
例如：
当我需要运行服务程序的时候，弹出我的应用程序，则要在Windows服务“允许服务与桌面交互”中打勾，
当我不想弹出应用程序界面的时候，则去掉其中的勾选。
实现方式：
1.在服务程序安装时编程实现，ProjectInstaller.cs
using System; using System.Collections; using System.Collections.Generic; using System.ComponentModel; using System.Configuration.Install; using Microsoft.Win32; //对注册表操作一定要引用这个命名空间 namespace MonitorService { [RunInstaller(true)] public partial class ProjectInstaller : Installer { public ProjectInstaller() { InitializeComponent(); //this.Context.Parameters["ServerCode"].ToString(); // 读取安装时输入的服务器编号 } private void ProjectInstaller_AfterInstall(object sender, InstallEventArgs e) { //设置允许服务与桌面交互 SetServiceTable("MonitorService"); } /// <summary> /// 设置允许服务与桌面交互 ,修改了注册表，要重启系统才能生效 /// </summary> /// <param name="ServiceName">服务程序名称</param> private void SetServiceTable(string ServiceName) { RegistryKey rk = Registry.LocalMachine; string key = @"SYSTEM/CurrentControlSet/Services/" + ServiceName; RegistryKey sub = rk.OpenSubKey(key, true); int value = (int)sub.GetValue("Type"); sub.SetValue("Type", value | 256); } } }
2.注册表修改
onstart的时候修改注册表
[HKEY_LOCAL_MACHINE"SYSTEM"CurrentControlSet"Services"你的服务名]
"Type"=dword:00000010
key value＋256
比如现在00000010是16＋256＝272
16精制就是00000110
3.SC程序修改， 允许与桌面进行交互
在dos命令提示符下输入：
sc config MonitorService type= interact type= own
回车即可。
可以用批处理的方式实现，把下面代码保存为 myservice.bat 即可：
rem 配置服务程序为允许与桌面进行交互方式
@echo "准备停止服务程序..."
sc stop MyService
@echo "设置允许与桌面进行交互方式允许"
sc config MyService type= interact type= own
@echo "正在重新启动服务..."
sc start MyService
@echo "启动服务成功！"
取消“允许与桌面进行交互”
DOS命令提示符下运行下面语句即可：
sc config MyService type= own
经测试：1，2 可以选中“允许与桌面进行交互”，但启动服务的时候，不能弹出应用程序的界面。
3 可以完美实现所有要求。
至此，我遇到的问题也完美的得到解决。
用VS2003部署，让服务程序安装完后立即启动服务并且选中“允许服务与桌面交互”及添加服务描述的方法
-----------立即启动-------------- private void serviceInstaller1_AfterInstall(object sender, System.Configuration.Install.InstallEventArgs e) { ServiceController myService = new ServiceController("XJOAPigeonholeServer"); myService.Start(); myService.Dispose(); } 添加描述：1.1没有直接方法，2.0里有直接的方法 ServiceInstaller.Description //----------------------------添加服务描述信息 开始 ------------ public override void Install(IDictionary stateServer) { Microsoft.Win32.RegistryKey system, //HKEY_LOCAL_MACHINE/Services/CurrentControlSet currentControlSet, //.../Services services, //.../ <Service Name> service, //.../Parameters - this is where you can put service-specific configuration config; try { //Let the project installer do its job base.Install(stateServer); //Open the HKEY_LOCAL_MACHINE/SYSTEM key system = Microsoft.Win32.Registry.LocalMachine.OpenSubKey("System"); //Open CurrentControlSet currentControlSet = system.OpenSubKey("CurrentControlSet"); //Go to the services key services = currentControlSet.OpenSubKey("Services"); //Open the key for your service, and allow writing service = services.OpenSubKey(this.serviceInstaller1.ServiceName, true); //Add your service's description as a REG_SZ value named "Description" service.SetValue("Description","XJOA系统自动归档服务(BeijiOffice)"); //(Optional) Add some custom information your service will use... //允许服务与桌面交互 service.SetValue("Type",0x00000110); config = service.CreateSubKey("Parameters"); } catch(Exception e) { Console.WriteLine("An exception was thrown during service installation:/n" + e.ToString()); } } public override void Uninstall(IDictionary stateServer) { Microsoft.Win32.RegistryKey system, currentControlSet, services, service; try { //Drill down to the service key and open it with write permission system = Microsoft.Win32.Registry.LocalMachine.OpenSubKey("System"); currentControlSet = system.OpenSubKey("CurrentControlSet"); services = currentControlSet.OpenSubKey("Services"); service = services.OpenSubKey(this.serviceInstaller1.ServiceName, true); //Delete any keys you created during installation (or that your service created) service.DeleteSubKeyTree("Parameters"); //... } catch(Exception e) { Console.WriteLine("Exception encountered while uninstalling service:/n" + e.ToString()); } finally { //Let the project installer do its job base.Uninstall(stateServer); } } //---------------------------- 结束 ----------------------------
四、这一服务程序运行时没有图形界面？
不错，刚才直接运行mfc1.exe时我们看到了图形界面，但在服务列表中用右键菜单中的“启动”时却看不到任何界面。这该怎么办？
我们还需要在使用CreateService函数时(Install()中)，加上一个参数，这样才能允许程序与桌面交互，也就是可以显示界面。这个参数是SERVICE_INTERACTIVE_PROCESS。
填加后的CreateService：
SC_HANDLE hService = ::CreateService(
hSCM, m_szServiceName, m_szServiceName,
SERVICE_ALL_ACCESS,
SERVICE_WIN32_OWN_PROCESS | SERVICE_INTERACTIVE_PROCESS,
SERVICE_DEMAND_START, SERVICE_ERROR_NORMAL,
szFilePath, NULL, NULL, _T("RPCSS"), NULL, NULL);
再次编译mfc1，卸载服务后，安装服务。我们可以看到，通过服务列表启动mfc1，原有的对话框出现了。
如需将服务设为自动启动，则将 SERVICE_DEMAND_START 改为 SERVICE_AUTO_START。
