.net操作IIS，新建网站，新建应用程序池，设置应用程序池版本，设置网站和应用程序池的关联

ServerManager类用来操作IIS，提供了很多操作IIS的API。使用ServerManager必须引用Microsoft.Web.Administration.dll，具体路径为：%windir%\System32\Inetsrv\Microsoft.Web.Administration.dll

以下代码展示了如何将自己的ASP.NET网站自动部署到IIS的过程，其中包括，新建网站-》新建应用程序池-》设置网站和应用程序池的关联-》重启网站和应用程序池

具体代码如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Web.Administration;

namespace AutoConfigureIIS
{
    internal class Program
    {
        //don't forget to add a reference to %windir%\System32\Inetsrv\Microsoft.Web.Administration.dll

        private static ServerManager serverMgr = new ServerManager();
        private static string applicationPoolName = "IPSRemoteApplicationPool";
        private static string applicationPoolVersion = "v4.0";
        private static string websiteName = "IPSRemoteSite";
        private static string port = "8998";
        private static string webPath = @"C:\Work\Published\SelfHostedIPSRemoteWeb";

        private static void Main(string[] args)
        {
            DeployIPSWeb();

            Console.Read();
        }

        /// <summary>
        /// Auto Configure IPS WebSite to IIS
        /// </summary>
        private static void DeployIPSWeb()
        {
            //create Application Pool
            if (!IsApplicationPoolExists(applicationPoolName))
            {
                CreateApplicationPool(applicationPoolName);
            }
            //create website
            if (!IsWebsiteExists(websiteName))
            {
                CreateWebSite(websiteName, port, webPath);
            }

            Site site = FindSiteBySiteName(websiteName); // get site by Index or by siteName
            ApplicationPool appPool = FindApplicationPoolByName(applicationPoolName);
                // get appPool by Index or by appPoolName

            site.Stop();
            site.ApplicationDefaults.ApplicationPoolName = appPool.Name;

            foreach (var item in site.Applications)
            {
                item.ApplicationPoolName = appPool.Name;
            }

            serverMgr.CommitChanges(); // this one is crucial!!! see MSDN: 
            // Updates made to configuration objects must be explicitly written to the configuration 
            // system by using the CommitChanges method!!
            site.Start();
            appPool.Recycle();
        }
