Get Image Byte

Hi folks,

I am using Asp.net Core and Novell.Directory.Ldap.NETStandard lib for Active Directory. Here is my sample code as below:

public struct PersonEntry
{
      ........
      ........
      public string Role { get; set; }public string ThumbnailPhoto { get; set; }
}

public IActionResult Test()
{
....
....
//Rest Omitted
        LdapAttribute attribute = (LdapAttribute)ienum.Current;
        string attributeName = attribute.Name;
        string attributeVal = attribute.StringValue;

        switch (attributeName)
        {
            case "sAMAccountName":
                entry.UserName = attributeVal;
                break;
            case "displayName":
                entry.Name = attributeVal;
                break;
            case "thumbnailPhoto":entry.ThumbnailPhoto = attributeVal;
                break;
            default:
                break;
        }
    }
    attributeListObject.Add(entry);
   }
   conn.Disconnect();
   return Ok(attributeListObject);

....
....
//Rest Omitted
