我看了,找不到一个简单的问题:
Windows服务如何确定启动它的ServiceName?
我知道安装可以破解注册表并添加一个命令行参数,但从逻辑上讲,似乎应该是不必要的,因此这个问题。
我希望比注册表黑客更干净地运行单个二进制文件的多个副本。
修改:
这是用C#编写的。我的应用 Main()入口点可以执行不同的操作,具体取决于 命令行参数:
目前,安装步骤会将服务名称和线程计数附加到注册表中的 ImagePath ,以便应用程序可以确定它的ServiceName。

这是一个WMI解决方案。覆盖 ServiceBase.ServiceMainCallback()也可能有效,但这似乎对我有用......
protected String GetServiceName()
{
// Calling System.ServiceProcess.ServiceBase::ServiceNamea allways returns
// an empty string,
// see https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=387024
// So we have to do some more work to find out our service name, this only works if
// the process contains a single service, if there are more than one services hosted
// in the process you will have to do something else
int processId = System.Diagnostics.Process.GetCurrentProcess().Id;
String query = "SELECT * FROM Win32_Service where ProcessId = " + processId;
System.Management.ManagementObjectSearcher searcher =
new System.Management.ManagementObjectSearcher(query);
foreach (System.Management.ManagementObject queryObj in searcher.Get()) {
return queryObj["Name"].ToString();
}
throw new Exception("Can not get the ServiceName");
}

ServiceBase.ServiceName属性给出了编译时的服务名称。如果在安装服务时指定其他名称,则ServiceName属性将不会提供正确的名称。所以,我必须使用下面的代码来获取我的服务的服务名称。
这是NVRAM方法的另一种选择(不使用LINQ):
/**
* Returns the service name of currently running windows service.
*/
static String getServiceName()
{
ServiceController[] scServices;
scServices = ServiceController.GetServices();
// Display the list of services currently running on this computer.
int my_pid = System.Diagnostics.Process.GetCurrentProcess().Id;
foreach (ServiceController scTemp in scServices)
{
// Write the service name and the display name
// for each running service.
// Query WMI for additional information about this service.
// Display the start name (LocalSytem, etc) and the service
// description.
ManagementObject wmiService;
wmiService = new ManagementObject("Win32_Service.Name='" + scTemp.ServiceName + "'");
wmiService.Get();
int id = Convert.ToInt32(wmiService["ProcessId"]);
if (id == my_pid)
{
return scTemp.ServiceName;
#if IS_CONSOLE
Console.WriteLine();
Console.WriteLine(" Service : {0}", scTemp.ServiceName);
Console.WriteLine(" Display name: {0}", scTemp.DisplayName);
Console.WriteLine(" Start name: {0}", wmiService["StartName"]);
Console.WriteLine(" Description: {0}", wmiService["Description"]);
Console.WriteLine(" Found.......");
#endif
}
}
return "NotFound";
}
我没有在第一次调用ServiceBase.Run()的情况下错误地尝试在main()中获取Windows服务的名称作为第一行。在获取名称之前,我们必须使用ServiceBase.Run()将可执行文件注册为服务。

Linq的短版
int processId = System.Diagnostics.Process.GetCurrentProcess().Id;
ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_Service where ProcessId = " + processId);
ManagementObjectCollection collection = searcher.Get();
var serviceName = (string)collection.Cast<ManagementBaseObject>().First()["Name"];

每个服务可执行文件必须实现的ServiceMain()入口点接收ServiceName作为其第一个输入参数。
如果您使用.NET编写服务,则ServiceMain()入口点由.NET实现。使用ServiceProcess.ServiceBase.ServiceName属性安装服务时,将分配ServiceName。如果您尝试自定义.NET服务以支持动态ServiceName值,我不知道如何在运行时访问实际的ServiceName。

this.ServiceName有什么问题,如果你在service.cs里面?
即:
protected override void OnStart(string[] args)
{
Logger.Info($"{this.ServiceName} started on {Environment.MachineName}...");
}

通过寻找更好的解决方案,我尝试了这个:
string serviceName = "myDynamicServiceName";
string serviceBin = "path\\to\\Service.exe";
string configFile = "path\\to\\myConfig.xml";
string credentials = "obj= .\\mytestuser password= test";
string scCommand = string.Format( "sc create {0} start= auto binPath= \"\\\"{1}\\\" -ini={2} -sn={3}\" type= own{4}", serviceName, serviceBin, configFile , serviceName ,credentials );
我将servicename和配置文件传递给binpath。 该服务是使用SC.exe安装的(我不使用installutil!)
在服务上,您可以获得Commandline-Arguments
protected override void OnStart(string[] args){
string binpath = new System.IO.FileInfo(System.Reflection.Assembly.GetAssembly(this.GetType()).Location).DirectoryName + "\\";
System.IO.StreamWriter sw = new System.IO.StreamWriter( binpath + "test.log");
sw.WriteLine( binpath );
string[] cmdArgs = System.Environment.GetCommandLineArgs();
foreach (string item in cmdArgs) {
sw.WriteLine(item);
}
sw.Flush();
sw.Dispose();
sw = null;
}

我有一个鸡与蛋问题,我需要在完成Service.Run()之前知道服务位置(服务可能是客户端或服务器安装的一部分,安装程序将它们命名为适当的,我需要检测哪个它是在启动时)
我依靠注册表为我命名。
public String IdentifySelfFromRegistry()
{
String executionPath = Assembly.GetEntryAssembly().Location;
Microsoft.Win32.RegistryKey services = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(
@"SYSTEM\CurrentControlSet\services");
if (services != null)
{
foreach(String subkey in services.GetSubKeyNames())
{
if (executionPath.Equals(ServicePathFromServiceKey(services.OpenSubKey(subkey))))
return subkey;
}
}
return String.Empty;
}
protected static String ServicePathFromServiceKey(Microsoft.Win32.RegistryKey serviceKey)
{
if (serviceKey != null)
{
String exec = serviceKey.GetValue(ServicePathEntry) as String;
if (exec != null)
return exec.Trim('\"');
}
return String.Empty;
}
