Hi Guru's

Hi ,

I wrote a below code :

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

namespace activeDirectoryLdapExamples
{
    class Program
    {
        static void Main(string[] args)
        {

            Console.Write("Enter user: ");
            String username = Console.ReadLine();

            if (username.Contains("."))
            {
               
                string[] splitString = username.Split(new char[] { '.' });
                username = splitString[splitString.Length - 1];
                Console.WriteLine(username);


            }


            try
            {
                // create LDAP connection object

                // DirectoryEntry myLdapConnection = createDirectoryEntry();

                DirectoryEntry entry = new DirectoryEntry("GC://Test", "Test\\Test", "Ld@Test", AuthenticationTypes.Secure);

                // create search object which operates on LDAP connection object
                // and set search object to only find the user specified

                // DirectorySearcher search = new DirectorySearcher(myLdapConnection);
                System.DirectoryServices.DirectorySearcher search = new System.DirectoryServices.DirectorySearcher(entry);
                //  search.Filter = "(cn=" + username + ")";

                search.Filter = "(sn=" + username + ")";
                // create results objects from search object

                SearchResult result = search.FindOne();

                if (result != null)
                {

                    // user exists, cycle through LDAP fields (cn, telephonenumber etc.)

                    ResultPropertyCollection fields = result.Properties;

                    foreach (String ldapField in fields.PropertyNames)
                    {
                        // cycle through objects in each field e.g. group membership
                        // (for many fields there will only be one object such as name)

                        foreach (Object myCollection in fields[ldapField])
                            Console.WriteLine(String.Format("{0,-20} : {1}", ldapField, myCollection.ToString()));

                    }
                }

                else
                {
                    // user does not exist
                    Console.WriteLine("User not found!");
                }
            }

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


    }
}

Am passing the string (eg:will.smith) in that case am using IF statement to get the last name (eg:smith) and using search.Filter = "(sn=" + username + ")";

Now i have a problem,if the string comes like (eg: Will(space )Smith) then i will take the whole string and use the search.Filter = "(cn=" + username + ")";

i was trying to put if statement in search filter but it doesn't work,some one please give me an idea.
