The program developed by c dynamically specifies the windows service name when it is installed

I was stumped. Did I want to set the desired name one by one in the developed code and then recompile it and register it as a service?
But what if I have to change the name in the future? Reset, compile, register again? This operation is too troublesome!
So I wondered if I could configure the installation, such as adding an xml file to record the service name of the service to be installed, and then modify the xml file before each installation.
Operation:
1. First, add a configuration file to the root directory of the main service program, and name it "ServiceSetting.xml" :

 
<?xml version="1.0" encoding="utf-8" ?> 
<Settings> 
<ServiceName>testme</ServiceName> 
<DisplayName>testmedisplay</DisplayName> 
<Description> This is just a test </Description> 
</Settings> 

2. Then add a class file to the root directory of the main service program, named "SettingHelper.cs" :

 
SettingHelper 
#region  The file  
//------------------------------------------------------------------------------------------------- 
//  Description: service installation configuration help class  
//  Author: bao haosheng  
//  Time: 2012-05-10

#endregion 
using System; 
using System.IO; 
using System.Xml; 
/// <summary>

/// </summary> 
internal class SettingHelper : IDisposable 
{ 
#region  Private members  
private string _ServiceName; 
private string _DisplayName; 
private string _Description; 
#endregion 
#region  The constructor  
/// <summary>

public SettingHelper() 
{ 
InitSettings(); 
}

get { return _ServiceName; } 
}

}

}

private void InitSettings() 
{ 
string root = System.Reflection.Assembly.GetExecutingAssembly().Location; 
string xmlfile = root.Remove(root.LastIndexOf('\\') + 1) + "ServiceSetting.xml"; 
if (File.Exists(xmlfile)) 
{ 
XmlDocument doc = new XmlDocument(); 
doc.Load(xmlfile); 
XmlNode xn = doc.SelectSingleNode("Settings/ServiceName"); 
_ServiceName = xn.InnerText; 
xn = doc.SelectSingleNode("Settings/DisplayName"); 
_DisplayName = xn.InnerText; 
xn = doc.SelectSingleNode("Settings/Description"); 
_Description = xn.InnerText; 
doc = null; 
} 
else 
{ 
throw new FileNotFoundException(" The service name profile could not be found  ServiceSetting.xml ! "); 
} 
} 
#endregion 
#endregion 
#region IDisposable  Members of the  
private bool disposed = false; 
public void Dispose() 
{ 
Dispose(true); 
GC.SuppressFinalize(this); 
} 
protected virtual void Dispose(bool disposing)

if (!this.disposed) 
{ 
if (disposing) 
{ 
//managed dispose 
_ServiceName = null;

_Description = null; 
} 
//unmanaged dispose 
} 
disposed = true; 
} 
~SettingHelper() 
{ 
Dispose(false); 
} 
#endregion 
} 

3. Modify the ProjectInstaller.cs file, and modify the constructor public ProjectInstaller() as follows:

 
ProjectInstaller 
using System.ComponentModel; 
using System.Configuration.Install; 
namespace WSInstallTest 
{ 
[RunInstaller(true)] 
public partial class ProjectInstaller : Installer 
{ 
public ProjectInstaller() 
{ 
InitializeComponent(); 
using (SettingHelper setting = new SettingHelper()) 
{ 
serviceInstaller1.ServiceName = setting.ServiceName; 
serviceInstaller1.DisplayName = setting.DisplayName; 
serviceInstaller1.Description = setting.Description; 
} 
} 
//end of class 
} 
} 

4. Execute the installation command:
In the start menu, find "Microsoft Visual Studio 2008" -- > "Visual Studio Tools" - > "Visual Studio 2008 command prompt", right click "run as administrator".
Enter the following command on the command line:

 
Setting environment for using Microsoft Visual Studio 2008 x86 tools. 
C:\Windows\system32>installutil /logfile d:\wsinstalltest.exe 

5. When the following text appears, the installation is successful

 
 Prompt for successful installation

 The parameter affected is :

logfile =

assemblypath = d:\wsinstalltest.exe 
logfile =

You can go to the services program to see that the service you just installed is installed.
6. Remarks:
Run sc start testme startup service;
Run "sc stop testme" to stop service;
Run "sc delete testme" to delete the service.
