  Out of range exception while trying to get user email address from Active Directory

  Mar 21, 2012 10:57 AM|LINK

  Hi,

  I am using the following code to get user email adrees from active directory.

  string _path = "LDAP://domain/DC=dc,DC=com";
  
  string domainAndUsername = domain + @"\" + username;
          DirectoryEntry entry = new DirectoryEntry(_path,
                                                     domainAndUsername,
                                                       pwd);
  
          try
          {
              // Bind to the native AdsObject to force authentication.
              Object obj = entry.NativeObject;
              DirectorySearcher search = new DirectorySearcher(entry);
              search.Filter = "(SAMAccountName=" + username + ")";
  
      search.PropertiesToLoad.Add("mail");
  
  
              SearchResult result = search.FindOne();
            
  
  if (result != null)
     {
       
       string mail=result.Properties["mail"][0].ToString();
      
     }

      But, I am getting System.ArgumentOutOfRangeException: ( Index was out of range. Must be non-negative and less than the size of the collection)

  For cn,everything works fine.What is the problem with .Properties["mail"]. Please help me to solve the issue

  //code for cn
  search.PropertiesToLoad.Add("cn");
  
   string cn=result.Properties["cn"][0].ToString();

  try

  string mail=result.Properties["mail"][0] as string;
  or
  string mail=result.Properties["userPrincipalName"][0] as string;

  If the account has not have the mail attribute populated you will get an error if you try and access it. You can use an if statement with result.properties.contains("mail") to check before trying to access the value

  check the above link it might help

  also check these two properties 

  proxyAddresses

  targetAddress

  Important : the account that performs the search must be a member of the Administrators group to retrieve the ntSecurityDescriptor property. If this is not the case, the property value that is returned for ntSecurityDescriptor will be null.

  Hi,

  string mail=result.Properties["userPrincipalName"][0] as string;

  
  

  is giving the name,.not mail id

  You need to change that line to the following to get the email

  string mail=result.Properties["mail"][0] as string;
