Send Email Attachments from a Form using Asp.Net and C#

Monday

how to send mail with attachment in asp.net using c#:
                                                                         In this tutorial you will learn how to send attachment with email in asp.net using c#. To send an email with attachments, the ASP.NET process (or the ASP.NET impersonated account) will need permission to read the file, and attach it to the MailMessage class. You can attach a  file using FileUpload Control and put the file in memory stream. In this example I'm using smtp.gmail.com as my SMTP server.  You can put your gmail login credentials and send mail with attachment.

In .aspx file

 <table style="padding-left: 10px; background-color: #4B8DF8; color: #fff; font-weight: bold;">
        <tr>
            <td colspan="2">
                <span class="primary"><b>Mail With Attachment:</b></span>
            </td>
        </tr>
        <tr>
            <td style="width: 30%">
                From :
            </td>
            <td>
                <asp:TextBox ID="txtFrom" SkinID="textbox_larger" runat="server"></asp:TextBox>
            </td>
        </tr>
        <tr>
            <td>
                To :
            </td>
            <td>
                <asp:TextBox ID="txtTo" SkinID="textbox_larger" runat="server"></asp:TextBox>
            </td>
        </tr>
        <tr>
            <td>
                Subject :
            </td>
            <td>
                <asp:TextBox ID="txtSubject" SkinID="textbox_larger" runat="server"></asp:TextBox>
            </td>
        </tr>
        <tr>
            <td>
                Message :
            </td>
            <td>
                <asp:TextBox ID="txtMessage" TextMode="MultiLine" SkinID="textbox_multiline_smaller"
                    runat="server"></asp:TextBox>
            </td>
        </tr>
        <tr>
            <td>
                Attach :
            </td>
            <td>
                <asp:FileUpload ID="FileUpload1" runat="server" />
            </td>
        </tr>
        <tr>
            <td>
                &nbsp;
            </td>
            <td align="left">
                <asp:Button ID="btnSendMail" runat="server" SkinID="button_primary" OnClick="btnSendMailWithAttachment_Click"
                    Text="Send Mail"></asp:Button>
            </td>
        </tr>
    </table>
