  Add and remove contacts from distribution lists (C#)

  Aug 05, 2011 06:34 PM|LINK

  I searched the forums and found a thread similar to what I'm trying to do here:

  http://forums.asp.net/t/1292982.aspx/1?add+and+remove+users+from+a+given+distribution+list+VB

  I'm trying to do the same thing in C# and can't figure out what I'm doing wrong.

  The following is code where I successfully added a Contact to Active Directory:

  public void CreateContact(UsersDTO userDTO, ContactsDTO contactsDTO, UserContactsDTO userContactsDTO)
          {
              // Binding object.
              DirectoryEntry directoryEntry;
              try
              {
                  directoryEntry = new DirectoryEntry("LDAP://OU=Contacts,OU=CLSRS,DC=dev,DC=lcb", username, password);
                  directoryEntry.RefreshCache();
                  DirectoryEntry contact = directoryEntry.Children.Add("CN=" + userDTO.FirstName + " " + userDTO.LastName, "Contact");
                  contact.Properties["sn"].Add("CN=" + userDTO.FirstName + " " + userDTO.LastName);
                  contact.Properties["givenName"].Add(userDTO.FirstName);
                  contact.Properties["mail"].Add(contactsDTO.EmailAddress);
                  contact.CommitChanges();
              }
              catch (Exception e)
              {
                  // Do some error processing
                  var msg = e.Message.ToString();
              }
          }
  
  Now I want to add that Contact to a distribution list, but I'm getting an error - There is a naming violation - and I don't know how to fix it. Here is my code:

  public void AddContactToGroup(string FirstName, string LastName, string GroupName)
          {
              // Binding object.
              DirectoryEntry directoryEntry;
              try
              {
                  directoryEntry = new DirectoryEntry("LDAP://CN=" + GroupName + ",OU=Groups,OU=CLSRS,DC=dev,DC=lcb", username, password);
                  directoryEntry.RefreshCache();
                  DirectoryEntry groupContact = directoryEntry.Children.Add("CN=" + FirstName + " " + LastName, "Contact");
                  groupContact.Properties["member"].Add("CN=" + FirstName + " " + LastName);
                  groupContact.CommitChanges();
              }
              catch (Exception e)
              {
                  // Do some error processing
                  var msg = e.Message.ToString();
                  throw;
              }
          }       }

  Finally got this working! Here is my working code:

  public void AddContactToGroup(string FirstName, string LastName, string GroupName)
          {
              // Binding object.
              DirectoryEntry directoryEntry;
              try
              {
                  directoryEntry = new DirectoryEntry("LDAP://CN=" + GroupName + ",OU=Groups,OU=CLSRS,DC=dev,DC=lcb", username, password);
                  directoryEntry.RefreshCache();
                  DirectoryEntry groupContact = new DirectoryEntry("LDAP://CN=" + FirstName + " " + LastName + ",OU=Contacts,OU=CLSRS,DC=dev,DC=lcb", username, password);
                  directoryEntry.Properties["member"].Add(groupContact.Properties["distinguishedName"].Value);
                  directoryEntry.CommitChanges();
              }
              catch (Exception e)
              {
                  // Do some error processing
                  var msg = e.Message.ToString();
                  throw;
              }
          }
