Introduction

This article describes how to send an email in C#. For sending the email, you need to configure the email services on the server.

Note: For more info about configuration read how to configure mail server.

To explain this article, I will use the following procedure after configuring the server:

Create a new website and add a page into it.
Add 3 textboxes into the page for receiver Email-ID, subject of Email and message of Email and a button for sending the mail.
Write some code in the ".cs" file to send the mail with some text for the button's Click event.

The following are the details of the preceding procedure.

Step 1: Create a new empty web site named "MailServer".

Step 2: Add a new Page named "SendingMail.aspx".

Add a Button with Onclick event (for sending the Email) on the page.

<table>
<tr>
<td>Mail To:-</td>
<td>
<asp:TextBox ID="txtEmail" runat="server" Width="200px">
</asp:TextBox></td>
</tr>
<tr>
<td>Subject:-</td>
<td>
<asp:TextBox ID="txtSubject" runat="server" Width="200px">
