Q:

how to send mail from .net?

I want to send email from my .net application. Please tell me the steps for sending email.

A:

Start by exploring  System.Net.Mail.SmtpClient type in .net. This type offers overload method Send.
Look here 

    public static void CreateTestMessage1(string server, int port)
    {
        string to = "jane@contoso.com";
        string from = "ben@contoso.com";
        string subject = "Using the new SMTP client.";
        string body = @"Using this new feature, you can send an e-mail message from an application very easily.";
        MailMessage message = new MailMessage(from, to, subject, body);
        SmtpClient client = new SmtpClient(server, port);
        // Credentials are necessary if the server requires the client 
        // to authenticate before it will send e-mail on the client's behalf.
        client.Credentials = CredentialCache.DefaultNetworkCredentials;

        try
        {
            client.Send(message);
        }
        catch (Exception ex)
        {
            Console.WriteLine("Exception caught in CreateTestMessage1(): {0}",
                  ex.ToString());
        }
    }
