Hi @BeUnique , Welcome to Microsoft Q&A,

To get the number of Active Directory users from C# without using a foreach loop, you can use the PrincipalSearcher class in the System.DirectoryServices.AccountManagement namespace. This allows you to perform a simple query to get the number of users. Below is a sample code in C# to get the number of Active Directory users without using a foreach loop, you can use the PrincipalSearcher class in the System.DirectoryServices.AccountManagement namespace. This allows you to perform a simple query to get the number of users. The following is a sample code

using System;
using System.DirectoryServices.AccountManagement;
using System.Linq;

namespace xxx
{
    internal class Program
    {
        static void Main(string[] args)
        {
            int userCount = GetActiveDirectoryUserCount();
            Console.WriteLine("Active Directory counts: " + userCount);
            Console.ReadLine();
        }
        static int GetActiveDirectoryUserCount()
        {
            using (PrincipalContext context = new PrincipalContext(ContextType.Domain))
            {
                UserPrincipal userPrincipal = new UserPrincipal(context);
                PrincipalSearcher searcher = new PrincipalSearcher(userPrincipal);
                var results = searcher.FindAll();
                return results.Count();
            }
        }
    }
}
