Reading Attributes of an Object

You can use the DirectoryEntry class's PropertyCollection and PropertyValueCollection collections to get an object's attributes. The following example demonstrates how to read and print the attributes of an Active Directory object.

Code Example: Reading Object Attributes

using System;
using System.DirectoryServices;

namespace Chapter12
{


          public class DirectoryBinding
          {
                  public DirectoryBinding()
                  {
                         DirectoryEntry MyDirectoryObject = new DirectoryEntry();
                        //Port 389 is LDAP port
                         MyDirectoryObject.Path =
                            "LDAP://HMSRevenge:389/OU=Users,DC=Test,DC=COM";
                         MyDirectoryObject.Username = @"Test\gregmcb";
                         MyDirectoryObject.Password = @"MyPassword";
                        //Gets the attributes of an object
                         PropertyCollection MyAttributes =
                              MyDirectoryObject.Properties;
                         foreach(string MyAttributeName in
                                    MyAttributes.PropertyNames)
                         {
                              //Gets the values of an object
                                PropertyValueCollection MyAttributeValues =
                                    MyAttributes[MyAttributeName];
                                foreach(string MyValue in MyAttributeValues)
                                {
                                       Console.WriteLine(MyAttributeName +
                                           " = " + MyValue);
                                }
                         }
                  }
          }
}

using System;
using System.DirectoryServices;

namespace Chapter12
{
          public class ReadingKnownDirectoryObjects
          {
                 public ReadingKnownDirectoryObjects()
                 {
                         DirectoryEntry MyObject = new DirectoryEntry();
                         MyObject.Path =
                             "LDAP://HMSRevenge/OU=Users,DC=Test,DC=com";
                         foreach(string MyValue in MyObject.Properties["email"])
                                 Console.WriteLine("Email" + " : " + MyValue);
                 }
         }
}
