我的理解是每个独立程序池的网站都有两个应用程序池的,第一个是网站的程序池,如果没有用代码指定,只是在IIS里添加或修改,是DefalutAppPool,第二个是网站下面虚拟目录用的程序池,是指定的那个
在IIS的网站属性里,主目录标签,应用程序池的下拉菜单里选择设置的应用程序池是虚拟目录的应用程序池,不是网站的,这个在C:\WINDOWS\system32\inetsrv\MetaBase.xml可以看出来,AppPoolId是定义在IIsWebVirtualDir节点里的
所以在读取AppPoolId时,要循环到虚拟目录
#region 取指定网站正在使用的应用程序池

public static string GetAppPoolForSite(string siteName)
{
string poolName = null;
using (DirectoryEntry root = new DirectoryEntry(webSitePath))
{
//取指定网站
foreach (DirectoryEntry site in root.Children)
{
if (site.SchemaClassName.Equals("IIsWebServer")
&&
site.Properties["ServerComment"].Value.ToString().Equals(siteName)
)
{
//取网站的应用程序池,如果是程序添加的,网站的应用程序池可以被手动指定
poolName = site.Properties["AppPoolId"].Value.ToString();
if (poolName.Equals("DefalutAppPool"))
{
//网站的应用程序池是默认的,取虚拟目录的应用程序池,如果是在IIS里修改过应用程序池,被修改的是虚拟目录的,从C:\WINDOWS\system32\inetsrv\MetaBase.xml的IIsWebVirtualDir节点可以看出
foreach (DirectoryEntry virtualDir in site.Children)

下面两个方法是取指定标志符的网站的信息,这个在修改网站资料时会用到:
#region 根据网站标志符,获取指定网站的入口
private static DirectoryEntry GetWebSiteEntry(string siteId)
{
DirectoryEntry webSite = null;
try
{
using (DirectoryEntry root = new DirectoryEntry(webSitePath))
{
webSite = root.Children.Find(siteId, "IIsWebServer");
if (webSite == null)
{
MessageBox.Show("指定网站不存在");
return null;
}
}
}
catch (Exception ex)
{
webSite = null;
MessageBox.Show("获取指定网站失败:" + ex.Message);
}
return webSite;
}
