The following C# example shows how to create an asynchronous search.

Copy

using System.DirectoryServices;
...
// Bind to the users container.
DirectoryEntry entry = new DirectoryEntry("LDAP://CN=users,DC=fabrikam,DC=com");
// Create a DirectorySearcher object.
DirectorySearcher mySearcher = new DirectorySearcher(entry);
//Set the Asynchronous property to true.
src.Asynchronous = true;
//Use the FindAll method to get search results.
SearchResultCollection res = src.FindAll();
