using System.DirectoryServices;
using System.Web.Configuration;

namespace IISMetabase
{
class IISMetabase
{
private string _machineName = "localhost";
private System.Collections.IDictionary _applications;//collection of websites
private Configuration _config;

public IISMetabase()
{
_applications = new System.Collections.Hashtable();
}

public System.Collections.IDictionary GetApplications()
{
DirectoryEntry webentry = new DirectoryEntry();
String path = "IIS://" + _machineName + "/W3SVC/1/ROOT";


webentry.Path = path;
Boolean exists = false;
try
{
exists = DirectoryEntry.Exists(path);
}
catch (System.Runtime.InteropServices.COMException e)
{
String error = e.Message;
Console.WriteLine(error + "\n");
}

if (exists)
{
DirectoryEntries webSiteChildren = webentry.Children;


foreach (DirectoryEntry website in webSiteChildren)
{
String scn = website.SchemaClassName;
String se = website.SchemaEntry.ToString();

if (website.Properties.Contains("KeyType"))
{
String webName = website.Name;

try
{
Object keyTypeValue = website.InvokeGet("KeyType");
String keyTypeValueStr = keyTypeValue.ToString();
if (!keyTypeValueStr.Equals(""))
{
try
{
_config = WebConfigurationManager.OpenWebConfiguration("/" + webName);

_applications.Add(webName, _config);
}
catch (ConfigurationErrorsException err)
{
String error = err.Message;
Console.WriteLine(error + "\n");
}
}
