Sorting POP3 message list

Question

Hi,

I want to sort the my messages by date. SO the newest email must show at the top. How can I do this? I am using the following code.

Pop3 client = new Pop3(); client.Connect("pop.gmail.com",995,null, Pop3Security.Implicit);

        client.Login("xxx", "xxx");

        Pop3MessageCollection messages = 
          client.GetMessageList(Pop3ListFields.FullHeaders);

        // display info about each message   
        Console.WriteLine("UID | From | To | Subject");
        foreach (Pop3MessageInfo message in messages)
        {
            Console.WriteLine(
               message.UniqueId.ToString() + "|" + 
               message.From.ToString() + "|" + 
               message.To.ToString() + "|" + 
               message.Subject.ToString());
        }

        client.Disconnect();

Hi,

if you are using .NET 3.5 or later you can do it by using LINQ extension method OrderBy() or OrderByDescending(), so your code will now like this:

Pop3MessageCollection messages = 
  client.GetMessageList(Pop3ListFields.FullHeaders);    

IEnumerable<Pop3MessageInfo> orderedAsc = 
   messages.OrderBy(m => m.Date.UniversalTime);

// display info about each message   
Console.WriteLine("UID | From | To | Subject");

foreach (Pop3MessageInfo message in orderedAsc)
{
     Console.WriteLine(
        message.UniqueId.ToString() + "|" + 
        message.From.ToString() + "|" +      
        message.To.ToString() + "|" + 
        message.Subject.ToString());
}
