Date Range in Active Directory using C#

Question

I was trying to find some example to retrieve user from Active Directory, based on Date Range.

For Eg: if i give a date like 1/01/2011 to 31/01/2011 in my windows application.

I wanna retrieve the user info , created on these date ranges.

For Eg: User Bob Created on 15/01/2001,then i have to retrieve that user name.

but am not sure what's the "Search Filter" for that.

Any help appreciated

The logic is good, you just need to adapt the example i gave to fit your programme:
you'll have to create 2 DateTime values for startDate and endDate.
so within the foreach loop you'll have something that look like the below:

<pre lang="xml">DirectoryEntry user = new DirectoryEntry("LDAP://" + result.GetDirectoryEntry().Properties["distinguishedName"].Value.ToString());

               if(user.Properties["whenCreated"].Value > startDate && user.Properties["whenCreated"].Value < endDate)
               {
                   Console.WriteLine(user.Properties["cn"].Value.ToString() + " - " + user.Properties["whenCreated"].Value.ToString());
               }

Solution 1

can you find all users and then use an IF statement to display the user created within these dates?

if(user.properties["whenCreated"].value > StartDate && user.properties["whenCreated"].value < EndData)
{
user.properties["whenCreated"].value.ToString()
}

please Correct me,if am not followed your logic in the below code

using System;
using System.Text;
using System.DirectoryServices;

namespace activeDirectoryLdapExamples
{
class Program
{
static void Main(string[] args)
{
Console.Write("Enter property: ");
String property = Console.ReadLine();

try
{
DirectoryEntry myLdapConnection = createDirectoryEntry();

DirectorySearcher search = new DirectorySearcher(myLdapConnection);
search.PropertiesToLoad.Add("cn");
search.PropertiesToLoad.Add(property);

SearchResultCollection allUsers = search.FindAll();

foreach(SearchResult result in allUsers)
{
if(user.properties["whenCreated"].value > StartDate && user.properties["whenCreated"].value < EndData)
{
user.properties["whenCreated"].value.ToString()
}

}
}

catch (Exception e)
{
Console.WriteLine("Exception caught:\n\n" + e.ToString());
}
}

static DirectoryEntry createDirectoryEntry()
{
// create and return new LDAP connection with desired settings

DirectoryEntry ldapConnection = new DirectoryEntry("rizzo.leeds-art.ac.uk");
ldapConnection.Path = "LDAP://OU=staffusers,DC=leeds-art,DC=ac,DC=uk";
ldapConnection.AuthenticationType = AuthenticationTypes.Secure;
return ldapConnection;
}
}
}
