How to pass parameters to Windows Service?

I tried to pass parameters to a windows service.

Here is my code snippet:

class Program : ServiceBase
{
    public String UserName { get; set; }
    public String Password { get; set; }

    static void Main(string[] args)
    {
        ServiceBase.Run(new Program());
    }

    public Program()
    {
        this.ServiceName = "Create Users Service";
    }

    protected override void OnStart(string[] args)
    {
        base.OnStart(args);

        String User = UserName;
        String Pass = Password;
        try
        {
            DirectoryEntry AD = new DirectoryEntry("WinNT://" + Environment.MachineName + ",computer");

            DirectoryEntry NewUser = AD.Children.Add(User, "user");
            NewUser.Invoke("SetPassword", new object[] { Pass });
            NewUser.Invoke("Put", new object[] { "Description", "Test User from .NET" });
            NewUser.CommitChanges();
            DirectoryEntry grp;
            grp = AD.Children.Find("Administrators", "group");
            if (grp != null)
            {
                grp.Invoke("Add", new object[] { NewUser.Path.ToString() });
            }
            Console.WriteLine("Account Created Successfully");
            Console.ReadLine();
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);
            Console.ReadLine();
        } 
    }

How do I pass UserName and Password to this windows service?

You can pass parameters on startup like this:

Right click on MyComputer and select Manage -> Services and Applications -> Services
Right click on your service, select Properties and you should then see the Start Parameters box under the General tab.

If you enter there for example User Password you will get these parameters in protected override void OnStart(string[] args) as args. then use it like this:

protected override void OnStart(string[] args)
{
    base.OnStart(args);
    UserName = args[0];
    Password = args[1];
    //do everything else
}

You are going to have to load these values up from an external source. The easiest is to load them directly from an app.config file, using the Configuration Manager. Something like this: http://msdn.microsoft.com/en-us/library/system.configuration.configurationmanager.appsettings.aspx

You can use configuration file, Registry or any type of databases.

Use Environment.GetCommandLineArgs()

The two cleanest ways to pass arguments (without using registry, files or a database) to a Windows Service at runtime is using Named Pipes or setting up a WCF Service in windows, that your client calls into. By default, a Windows Service is meant to be a repetitive process that runs.

If you use WCF, turn it on in Add Remove Programs (or Programs and Features for Windows 7).

Named Pipes:
