Create class name SMTP.cs then

using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Net.Mail;
using System.Net.Mime;
using System.Net;



/// 

/// Summary description for SMTP
/// 
public class SMTP
{
    private SmtpClient smtp;

    private static string _smtpIp;
    public static string smtpIp
    {
        get
        {
            if (string.IsNullOrEmpty(_smtpIp))
                _smtpIp = System.Configuration.ConfigurationManager.AppSettings["smtpIp"];

            return _smtpIp;

        }
    }


    public SMTP()
    {
        smtp = new SmtpClient(smtpIp);
     }

    public string Send(string From, string Alias, string To, string Subject, string Body, string Image)
    {
        try
        {
            MailMessage m = new MailMessage("\"" + Alias + "\" <" + From + ">", To);
            m.Subject = Subject;
            m.Priority = MailPriority.Normal;

            AlternateView av1 = AlternateView.CreateAlternateViewFromString(Body, System.Text.Encoding.UTF8, MediaTypeNames.Text.Html);

            if (!string.IsNullOrEmpty(Image))
            {
                string path = HttpContext.Current.Server.MapPath(Image);
                LinkedResource logo = new LinkedResource(path, MediaTypeNames.Image.Gif);
                logo.ContentId = "Logo";
                av1.LinkedResources.Add(logo);
            }

            m.AlternateViews.Add(av1);
            m.IsBodyHtml = true;

            smtp.Send(m);
        }
        catch (Exception e)
        {
            return e.Message;
        }

        return "sucsess";
    }
}

then 

on aspx page

protected void lblSubmit_Click(object sender, EventArgs e)
    {
        //HttpContext.Current.Response.ContentType = "text/plain";
        //Guid guid = Guid.NewGuid();
        string EmailMessage = "" +
                                      "" +
                                          "" +
                                      "" +
                                       "" +
                                       "" +

                                               //"Test

                                      "" +
                                  "";

        lblThank.Text = "Thank you for contact us.";
       // string Body = commentsID.Text;
        SMTP smtp = new SMTP();
        string FromEmail = System.Configuration.ConfigurationManager.AppSettings["FromEmail"];
        string mailReturn = smtp.Send(EmailID.Value, "", FromEmail, "Contact Us Email", EmailMessage, string.Empty);
        //HttpContext.Current.Response.Write("true");
        nameID.Value = "";
        EmailID.Value = "";
        commentsID.Text = "";
    }
