How to send a submitted email to an email - asp.net

Question

I am currently using a template in order to create a website. In the contact page I want to create a form where the user will be able to contact the company from a contact us template. The template comes with a contact_us.php file but I want to use only asp.net for the emails.
I am a beginner and I am not really sure how the controllers works in asp.net.
Heres my code:
View: Contact.cshtml
#model Gsite.Models.ContactUs
#{
Layout = "~/Views/Shared/_CustomLayout.cshtml";
}
<script src="~/Content/vendor/jquery/jquery.js"></script>
<script src="~/Content/vendor/jquery/jquery.min.js"></script>
<!-- Contact Form -->
<!-- In order to set the email address and subject line for the contact form go to the bin/contact_me.php file. -->
<div class="row">
<div class="col-lg-8 mb-4">
<h3>Send us a Message</h3>
#if (ViewBag.Message == null)
{
<form method ="post" name="sentMessage" id="contactForm" novalidate>
<div class="control-group form-group">
<div class="controls">
<label asp-for="Name">Full Name:</label>
<input asp-for="Name" type="text" class="form-control" id="name" required data-validation-required-message="Please enter your name.">
<span asp-validation-for="Name"
class="text-muted"></span>
<p class="help-block"></p>
</div>
</div>
<div class="control-group form-group">
<div class="controls">
<label asp-for="phonenumber">Phone Number:</label>
<input asp-for="phonenumber" type="tel" class="form-control" id="phone" required data-validation-required-message="Please enter your phone number.">
<span asp-validation-for="phonenumber"
class="text-muted"></span>
</div>
</div>
<div class="control-group form-group">
<div class="controls">
<label asp-for="Email">Email Address:</label>
<input asp-for="Email" type="email" class="form-control" id="email" required data-validation-required-message="Please enter your email address.">
<span asp-validation-for="Email"
class="text-muted"></span>
</div>
</div>
<div class="control-group form-group">
<div class="controls">
<label asp-for="Message">Message:</label>
<textarea asp-for="Message" rows="10" cols="100" class="form-control" id="message" required data-validation-required-message="Please enter your message" maxlength="999" style="resize:none"></textarea>
<span asp-validation-for="Message"
class="text-muted"></span>
</div>
</div>
<div id="success"></div>
<!-- For success/fail messages -->
<button type="submit" class="btn btn-primary" id="sendMessageButton">Send Message</button>
</form>
}
</div>
</div>
<!-- /.row -->

Answer 1

This will work in an Asp.net MVC application. Does the application has got both Asp.net MVC and Php codes? Assuming 'yes', you need to set the action property of the form element.
e.g. <form action="/Contact/Contact">
Also set the "name" property of the input boxes to match the properties of the ContactUs object.
