FIX: Memory leak when the IIS ADSI provider retrieves some metabase properties in IIS 7.5

using System; using System.Text; using System.DirectoryServices; using System.Threading; using System.Diagnostics; namespace DirEntryProps2 { class Program { static void Main(string[] args) { Console.WriteLine("Press ENTER to begin"); Console.ReadLine(); String szPath = "IIS://localhost/W3SVC/1/Root"; int i = 0; Console.WriteLine("Press CTRL+C to break"); for (; ; ) { DirectoryEntry virtualDirectoryEntry = new DirectoryEntry(szPath); Console.WriteLine(virtualDirectoryEntry.Properties.PropertyNames.Count.ToString() + " property names"); if (i == 0) { Console.WriteLine("Directory services items now loaded. Ready to start memory leak."); Console.ReadLine(); GC.Collect(2); GC.Collect(2); GC.WaitForPendingFinalizers(); GC.Collect(2); } foreach (string propertyName in virtualDirectoryEntry.Properties.PropertyNames) { //.. Perform operations here } Console.WriteLine(i++.ToString()); Thread.Sleep(10); virtualDirectoryEntry.Dispose(); GC.Collect(2); GC.Collect(2); GC.WaitForPendingFinalizers(); GC.Collect(2);                if (i > 1000) break; } Console.WriteLine("Finished!"); Console.ReadLine(); } } }
