 public bool IsHolidays(DateTime dt1)

Enumerating different items from Arrays

This morning I started to working on some thing to compare the two array list or array values and identifying the similarities and differential items.
The below code is equivalent to looping the both arrays and identifying the common and different items in two array values.

In C#.NET 3.5 We have Intersect and Except extension method to get solution for these kind scenarios.
List List1 = new List();

List List2 = new List();

List exce = List1.Except(List2).ToList();
foreach (string n in exce)
//It will returns the GuruSelvam

C# SMTP email sending code

When I tested this code in webapplication its works fine.But my webmail server is HTTPS based and I wanted to integrate this into my SharePoint webpart.

In this case,set EnableSsl true on your smtp object and specify the port number if you are not using the SMTP's default port 25.

Still you got an error use the below code to off the Certificate Validation while relying on HTTP.
If you are an developer and testing it on the PC where you installed "fiddler".Just make sure its Off.
Use the below line just before to Send method.
 System.Net.ServicePointManager.ServerCertificateValidationCallback = delegate(object s, X509Certificate certificate, X509Chain chain, SslPolicyErrors sslPolicyErrors) { return true; }; 
            MailMessage mail = new MailMessage();
            SmtpClient smtp = new SmtpClient("webmail smtp");

            mail.From = new MailAddress("");

            mail.Subject = "Subject";
            mail.Body = "Email contents";

            smtp.Credentials = new System.Net.NetworkCredential("userid", "pwd");
            smtp.EnableSsl = true;

            Response.Write("Sent !");
        catch (Exception ex)
