using System.Net.Mail;
using System.IO;

 protected void Button1_Click(object sender, EventArgs e)
    {
        try
        {
            MailMessage message = new MailMessage();
            message.From = new MailAddress("Sender Email ID", "Sender name");
            message.To.Add(txtemail.Text);

            message.Priority = MailPriority.High;

            HttpFileCollection fileCollection = Request.Files;
            for (int i = 0; i < fileCollection.Count; i++)
            {
                HttpPostedFile uploadfile = fileCollection[i];
                string fileName = Path.GetFileName(uploadfile.FileName);
                if (uploadfile.ContentLength > 0)
                {
                    uploadfile.SaveAs(Server.MapPath("~/upload/") + fileName);
                }
            }
            string Uplodefile = Request.PhysicalApplicationPath + "upload\\";
            string[] S1 = Directory.GetFiles(Uplodefile);
            foreach (string files in S1)
            {
                message.Attachments.Add(new Attachment(files));
            }

            message.IsBodyHtml = true;
            SmtpClient smtp = new SmtpClient();
            smtp.Host = "smtp.gmail.com";
            smtp.Port = 587;
            smtp.Credentials = new System.Net.NetworkCredential("sender@gmail.com", "password");
            smtp.EnableSsl = true;
            smtp.Send(message);
            message.Dispose();
            Clear();
            foreach (string file in S1)
            {
                File.Delete(file);
            }
        }
        catch (Exception ex)
        {

    }
    public void Clear()
    {
        txtemail.Text = "";
        txtmessage.Text = "";
        txtsubject.Text = "";
    }

VB Code:
Imports System.Net.Mail
Imports System.IO

Protected Sub Button1_Click(sender As Object, e As System.EventArgs) Handles Button1.Click
        Dim message As New MailMessage()
        message.From = New MailAddress("Sender Email ID", "Sender name")
        message.[To].Add(txtemail.Text)
        message.Subject = txtsubject.Text
        message.Body = txtmessage.Text
        message.Priority = MailPriority.High

        Dim fileCollection As HttpFileCollection = Request.Files
        For i As Integer = 0 To fileCollection.Count - 1
            Dim uploadfile As HttpPostedFile = fileCollection(i)
            Dim fileName As String = Path.GetFileName(uploadfile.FileName)
            If uploadfile.ContentLength > 0 Then
                uploadfile.SaveAs(Server.MapPath("~/upload/") & fileName)
            End If
        Next
        Dim Uplodefile As String = Request.PhysicalApplicationPath + "upload\"
        Dim S1 As String() = Directory.GetFiles(Uplodefile)
        For Each files As String In S1
            message.Attachments.Add(New Attachment(files))
        Next
        message.IsBodyHtml = True
        Dim smtp As New SmtpClient()
        smtp.Host = "smtp.gmail.com"
        smtp.Port = 587
        smtp.Credentials = New System.Net.NetworkCredential("sender@gmail.com", "password")
        smtp.EnableSsl = True
        smtp.Send(message)
        message.Dispose()
