以编程方式从 Windows 2003 服务器控制 IIS 7 服务器

我们使用 Windows 2003 服务器运行各种作业。其中一些作业将应用程序池命令发送到运行 IIS 6 的 Web 服务器（回收、启动、停止）。现在我们有一个运行 IIS 7 的 Windows 2008 Web 服务器，并且我们想要发送相同的命令。这一切都是使用 C# 完成的。

这是我们用来发送 IIS 6 命令的代码：

var methodToInvoke = "Stop"; // could be "Stop", "Start", or "Recycle"
var co = new ConnectionOptions
{
   Impersonation = ImpersonationLevel.Impersonate,
   Authentication = AuthenticationLevel.PacketPrivacy
};

var objPath = string.Format("IISApplicationPool.Name='W3SVC/AppPools/{0}'", appPoolName);
var scope = new ManagementScope(string.Format(@"\\{0}\root\MicrosoftIISV2", machineName), co);

using (var mc = new ManagementObject(objPath))
{
   mc.Scope = scope;
   mc.InvokeMethod(methodToInvoke, null, null);
}

由于底层更改，此代码不适用于 IIS 7，因此我们当前正在尝试此操作：

using (ServerManager serverManager = ServerManager.OpenRemote(machineName))
{
   var appPool = serverManager.ApplicationPools[appPoolName];
   if (appPool != null)
   {
      appPool.Stop(); // or app.Start() or app.Recycle()
      serverManager.CommitChanges();
   }
}

上面的代码在运行 Windows 7 的工作站上运行良好（并且，因此，IIS 7.5）。但是，当我将此代码部署到我们的应用程序服务器时，它不起作用。它收到此错误：

System.InvalidCastException: 
Unable to cast COM object of type 'System.__ComObject' to interface type 
'Microsoft.Web.Administration.Interop.IAppHostWritableAdminManager'. 
This operation failed because the QueryInterface call on the COM component for the 
interface with IID '{FA7660F6-7B3F-4237-A8BF-ED0AD0DCBBD9}' failed due to the following error: 
Interface not registered (Exception from HRESULT: 0x80040155).

根据我的研究，这是由于 IIS 7 在 Windows Server 2003 服务器上不可用。（我确实包含了 Microsoft.Web.Administration.dll 文件。）

所以我的问题是：

上述 IIS 7 代码是否可以在 Windows 2003 服务器上工作？
如果#1 不，有更好的方法吗？

原文

We run various jobs using a Windows 2003 server. Some of these jobs send app pool commands to web servers running IIS 6 (recycle, start, stop). Now we have a Windows 2008 web server running IIS 7, and we want to send the same commands. This is all done using C#.

This is the code we use to send commands for IIS 6:

var methodToInvoke = "Stop"; // could be "Stop", "Start", or "Recycle"
var co = new ConnectionOptions
{
   Impersonation = ImpersonationLevel.Impersonate,
   Authentication = AuthenticationLevel.PacketPrivacy
};

var objPath = string.Format("IISApplicationPool.Name='W3SVC/AppPools/{0}'", appPoolName);
var scope = new ManagementScope(string.Format(@"\\{0}\root\MicrosoftIISV2", machineName), co);

using (var mc = new ManagementObject(objPath))
{
   mc.Scope = scope;
   mc.InvokeMethod(methodToInvoke, null, null);
}

This code doesn't work for IIS 7 due to underlying changes, so we're currently trying this:

using (ServerManager serverManager = ServerManager.OpenRemote(machineName))
{
   var appPool = serverManager.ApplicationPools[appPoolName];
   if (appPool != null)
   {
      appPool.Stop(); // or app.Start() or app.Recycle()
      serverManager.CommitChanges();
   }
}

The above code works fine on my workstation, which runs Windows 7 (and, thus, IIS 7.5). However, it does not work when I deploy this code to our application server. It get this error:

System.InvalidCastException: 
Unable to cast COM object of type 'System.__ComObject' to interface type 
'Microsoft.Web.Administration.Interop.IAppHostWritableAdminManager'. 
This operation failed because the QueryInterface call on the COM component for the 
interface with IID '{FA7660F6-7B3F-4237-A8BF-ED0AD0DCBBD9}' failed due to the following error: 
Interface not registered (Exception from HRESULT: 0x80040155).

From my research, this is due to the fact that IIS 7 is not available on the Windows Server 2003 server. (I did include the Microsoft.Web.Administration.dll file.)

So my questions are:
