如何在C#中查找IIS站点ID？

using System;
using Microsoft.Web.Administration;

class Program
{
    static void Main(string[] args)
    {
        using (ServerManager serverManager = new ServerManager())
        {
            foreach (Site site in serverManager.Sites)
            {
                Console.WriteLine("站点名称: {0}", site.Name);
                Console.WriteLine("站点ID: {0}", site.Id);
            }
        }
    }
}

Install-Package Microsoft.Web.Administration
