        <asp:TextBox ID="YourName" runat="server" Width="250px" /><br />
        Your email address:
        <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="*"
            ControlToValidate="YourEmail" ValidationGroup="save" /><br />
        <asp:TextBox ID="YourEmail" runat="server" Width="250px" />
        <asp:RegularExpressionValidator runat="server" ID="RegularExpressionValidator23"
            SetFocusOnError="true" Text="Example: username@gmail.com" ControlToValidate="YourEmail"
            ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*" Display="Dynamic"
            ValidationGroup="save" /><br />
        Subject:
        <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ErrorMessage="*"
            ControlToValidate="YourSubject" ValidationGroup="save" /><br />
        <asp:TextBox ID="YourSubject" runat="server" Width="400px" /><br />
        Your Question:
        <asp:RequiredFieldValidator ID="RequiredFieldValidator3" runat="server" ErrorMessage="*"
            ControlToValidate="Comments" ValidationGroup="save" /><br />
        <asp:TextBox ID="Comments" runat="server" 
                TextMode="MultiLine" Rows="10" Width="400px" />
    </p>
    <p>
        <asp:Button ID="btnSubmit" runat="server" Text="Send" 
                    OnClick="Button1_Click" ValidationGroup="save" />
    </p>
</asp:Panel>
<p>
    <asp:Label ID="DisplayMessage" runat="server" Visible="false" />
</p>  

The server side code:

C#
protected void SendMail()
{
    // Gmail Address from where you send the mail
    var fromAddress = "Gmail@gmail.com";
    // any address where the email will be sending
    var toAddress = YourEmail.Text.ToString(); 
    //Password of your gmail address
    const string fromPassword = "Password";
     // Passing the values and make a email formate to display
    string subject = YourSubject.Text.ToString();
    string body = "From: " + YourName.Text + "\n";
    body += "Email: " + YourEmail.Text + "\n";
    body += "Subject: " + YourSubject.Text + "\n";
    body += "Question: \n" + Comments.Text + "\n";
    // smtp settings
    var smtp = new System.Net.Mail.SmtpClient();
    {
        smtp.Host = "smtp.gmail.com";
        smtp.Port = 587;
        smtp.EnableSsl = true;
        smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
        smtp.Credentials = new NetworkCredential(fromAddress, fromPassword);
        smtp.Timeout = 20000;
    }
    // Passing values to smtp object
    smtp.Send(fromAddress, toAddress, subject, body);
}

protected void Button1_Click(object sender, EventArgs e)
{
    try
    {
        //here on button click what will done 
        SendMail();
        DisplayMessage.Text = "Your Comments after sending the mail";
        DisplayMessage.Visible = true;
        YourSubject.Text = "";
        YourEmail.Text = "";
        YourName.Text = "";
        Comments.Text = "";
    }
    catch (Exception) { }
}

The above code has the validation checks also.

This code is based on the 3.5 framework and also works in the 4.0 framework.

Since this article pops out as the first link when doing a Google search for "ASP.NET contact form", and it also has (at this moment) a perfect 5.00 rating, you should really consider fixing the code.

As others have already pointed out, this code will send a message to sender's email address, not yours. Those fromAddress and toAddress variables are mixed up.

Additionally, it would make sense to put your credentials, host settings and target address inside web.config and read it at run-time. Hard-coding passwords is rarely a smart decision.
