Asp.Net Mail Script in C# and VB.Net

 

Writing your own mail script for a contact page for your own web site may not be that easy, even for experienced web developers, as most of the scripts, available on the internet, can be really confusing. Some of them are written for internal websites where the site administrator contact his subordinates through emails. It servers very little to a website owner who wants to make a webpage through which his customers can contact him.

The following scripts, written in C#, is addressing this issue once and for all.

Contact Form for an ASP.Net Page

Suppose, you own a vehicle hire firm and registered customers can contact you with the particular vehicle they need on a given day.

Code in .aspx Page button:

<table width="550px">
<tr>
<td"><asp:Label ID="Label2" runat="server" Text="Name:" Font-Size="Small"></asp:Label>
</td>
<td><asp:TextBox ID="txtName" runat="server" Height="25px" Width="250px"></asp:TextBox></td>

<asp:ListItem>Van</asp:ListItem>
<asp:ListItem>Lorry</asp:ListItem>

</td>
<td><asp:Button ID="btnSend" runat="server" CssClass="centralized" Text="Send the Mail" Height="40px" /></td>
<td><asp:Button ID="btnClear" runat="server" CssClass="centralized" Height="40px" Text="Clear" /></td>
</tr>
<tr>
<td colspan="3"><asp:ImageButton ID="imgThumbsup" runat="server" Visible="False" ImageUrl="" />

</tr>
</table>

Validation controls are being used along with the input controls to make sure users fill in the right values.

Next thing, we need to do is to write the code for btnSend button and btnClear button for their respective roles:

When the btnSend button is clicked, the validation controls check the input values on the client side and then send the email.

C# Code for aspx.cs page:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
// namespaces needed to use classes of mail
using System.Net;
using System.Net.Mail;
public partial class contact : System.Web.UI.Page
{
protected void btnSend_Click1(object sender, EventArgs e)
{
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
message.From = new MailAddress(txtEmail.Text, txtName.Text);
//Add the email of the autohiring.com
message.To.Add("info@autohiring.com");
message.IsBodyHtml = true;
message.Subject = RadioButtonList1.SelectedValue.ToString();
message.Body = txtQuery.Text;
System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient();
try
{
//instructions to use SMTP server of autohiring.com
smtp.Host = "127.0.0.1";
smtp.Send(message);
lblMessage.ForeColor = System.Drawing.Color.Green;
lblMessage.Text = "Thank you. We will reply soon.";
}
catch (SmtpException ex)
{
lblMessage.ForeColor = System.Drawing.Color.Red;
lblMessage.Text = ex.Message;
}
}
protected void btnClear_Click1(object sender, EventArgs e)
{
{
//input controls are cleared
txtEmail.Text = "";
txtName.Text = "";
txtQuery.Text = "";
lblMessage.Text = "";
RadioButtonList1.SelectedIndex =-1;
txtName.Focus();
}
}
}

VB.Net Code for aspx.vb page

Imports System.Collections.Generic
Imports System.Linq
Imports System.Web
Imports System.Web.UI
Imports System.Web.UI.WebControls
Imports System.Net
Imports System.Net.Mail
System.Net.Mail.MailMessage message = new System.Net.Mail.MailMessage();
message.From = new MailAddress(txtEmail.Text, txtName.Text);
'Add the email of the autohiring.com
message.To.Add("info@autohiring.com");
message.IsBodyHtml = true;
message.Subject = RadioButtonList1.SelectedValue.ToString();
message.Body = txtQuery.Text;
System.Net.Mail.SmtpClient smtp = new System.Net.Mail.SmtpClient();
try
'instructions to use SMTP server of autohiring.com
smtp.Host = "127.0.0.1";
smtp.Send(message);
lblMessage.ForeColor = System.Drawing.Color.Green;
lblMessage.Text = "Thank you. We will reply soon.";
catch (SmtpException ex)
lblMessage.ForeColor = System.Drawing.Color.Red;
lblMessage.Text = ex.Message;

The mail script uses .System.Mail object, its properties and methods to achieve the goal - sending and receiving emails with ease. It is explained above.

The code for btnClear button is the same for VB.Net.
