In this case it’s using IIS 7 so the .NET version isn’t selectable as it’s selected as part of the Application
Pool. For IIS 6 both .NET version and App Pool are available for IIS 5 only the .NET version is available.
.NET.
I talked about using ADSI for IIS with .NET a long while back with some examples of how to get virtuals and set properties etc. there.
So, here’s some additional code to deal with Application Pools in my WebConfiguration class (note there are a few depencies in this code, but you should be able to glean the generalidea):
/// <summary>
/// Returns a list of allthe Application Pools configured
/// </summary>/// <returns></returns>
public ApplicationPool[] GetApplicationPools(){
ServerType != WebServerTypes.IIS7)
return null;DirectoryEntry root = this.GetDirectoryEntry("IIS://" + this.DomainName
+ "/W3SVC/AppPools");
if (root == null)
return null;
List<ApplicationPool> Pools = new List<ApplicationPool>();foreach (DirectoryEntry Entry in root.Children)
{ PropertyCollection Properties = Entry.Properties;
ApplicationPool Pool = new ApplicationPool();
Pool.Name = Entry.Name;
Pools.Add(Pool);
}
return Pools.ToArray();}
///<summary>
/// Create a new Application Pool and return an instance of the entry
/// </summary>/// <param name="AppPoolName"></param>
/// <returns></returns>public DirectoryEntry CreateApplicationPool(string AppPoolName)
{ if (this.ServerType != WebServerTypes.IIS6 &&
this.ServerType != WebServerTypes.IIS7)
return null;
DirectoryEntry root = this.GetDirectoryEntry("IIS://" + this.DomainName
+ "/W3SVC/AppPools");
return null;
DirectoryEntry AppPool = root.Invoke("Create","IIsApplicationPool",AppPoolName) as DirectoryEntry;
AppPool.CommitChanges();
return AppPool;
}
/// <summary>
/// Returns an instance of an Application Pool/// </summary>
/// <param name="AppPoolName"></param>
/// <returns></returns>public DirectoryEntry GetApplicationPool(string AppPoolName)
{DirectoryEntry root = this.GetDirectoryEntry("IIS://" + this.DomainName + "/W3SVC/AppPools/" + AppPoolName);
return root;}
/// <summary>
/// Retrieves an Adsi Node by its path. Abstracted for error handling/// </summary>/// <param name="Path">the ADSI path to retrieve: IIS://localhost/w3svc/root</param>
/// <returns>node or null</returns>private DirectoryEntry GetDirectoryEntry(string Path)
{ DirectoryEntry root = null;
try
{ root = new DirectoryEntry(Path);
}
catch{
this.SetError("Couldn't access node"); return null;}
if (root == null)
{ this.SetError("Couldn't access node");
return null;
}return root;
}
IIS://localhost/W3SVC/AppPools
And you can access a specific pool through the Children collection. For ADSI paths a child looks like this:
IIS://localhost/W3SVC/AppPools/DefaultAppPoolFrom there you get a DirectoryEntry object and you can fire away on the properties of the pool and set thing like the impersonating account and various health checks. I didn’t need to
look closely at this but I couldn’t find the MSDN documentation on IIsApplicationPool that shows the member properties. The MSDN documentation for IIS’s ADSI support (and even the IIS6 WMI support) is
just plain awful and scattered through many places. If anybody happens to find a link with the member properties post it here.
Once you have an Application Pool it can be attached to a virtual directory/Application via its AppPoolId:
DirectoryEntry VDir = new DirectoryEntry("IIS://localhost/W3SVC/ROOT/WebStore");VDir.Properties["AppPoolId"].Value = this.ApplicationPool;
VDir.CommitChanges();
And there you have it. I’ve updated the Web Configuration Utility online and it includes the AppPool configuration code, and a recent update to the West Wind Web Store also includes this code as part of the configuration.
using System.DirectoryServices;
using System;
public class IISAdmin
{
public static void GetWebsiteID(string websiteName)
{
DirectoryEntry w3svc = new DirectoryEntry("IIS://localhost/w3svc");
foreach(DirectoryEntry de in w3svc.Children)
{
if(de.SchemaClassName == "IIsWebServer" && de.Properties["ServerComment"][0].ToString() == websiteName)
{
Console.Write(de.Name);
}
}
}
public static void Main()
{
GetWebsiteID("Default Web Site");
}
-----------------------------------------------------------
You are looking for ServerManager
(Microsoft.Web.Administration) which provides read and write
access to the IIS 7.0 configuration system.
Iterate through Microsoft.Web.Administration.SiteCollection, get a
reference to your website using the Site Object and read the value of
the Name property.
// Snippet
using (ServerManager serverManager = new ServerManager()) {
var sites = serverManager.Sites;
foreach (Site site in sites) {
Console.WriteLine(site.Name); // This will return the WebSite name
}
You can also use LINQ to query the ServerManager.Sites collection
(see example below)
// Start all stopped WebSites using the power of Linq :)
var sites = (from site in serverManager.Sites
where site.State == ObjectState.Stopped
orderby site.Name
select site);
foreach (Site site in sites) {
site.Start();
}
