Send Email From A Razor Page In .NET Core 2 Using System.Net.Mail

3. The newly created properties should be assigned to their respective form values. So, to achieve this, we will add the form tag with some textbox in the “Index.cshtml” page.
   
   1. @page
   2. @model Horizon.Core.Test.Pages.Customers.IndexModel
   4. @{
   5. ViewData["Title"] = "Index";
   6. }
   8. <h2>Index</h2>
   10. <p>
   11. <a asp-page="Create">Create New</a>
   12. </p>
   14. <form asp-page="./Index" method="post" enctype="multipart/form-data">
   15. <div class="form-actions no-color">
   16. <p>
   17. From : <input type="text" asp-for="email.From" /><br />
   18. To : <input type="text" asp-for="email.To" /><br />
   19. Subject : <input type="text" asp-for="email.Subject" /><br />
   20. Body : <textarea asp-for="email.Body"></textarea><br />
   21. <button asp-page-handler="SendEmail">Send Email</button>
   22. </p>
   23. </div>
   24. </form>

4. Send email by calling the SendEmailAsync method by putting below code in “Index.cshtml.cs” page. Make sure to insert the “using System.Net.Mail” directive.
   
   1. public async Task OnPostSendEmail()
   2. {
   3. using (var smtp = new SmtpClient("Your SMTP server address"))
   4. {
   5. var emailMessage = new MailMessage();
   6. emailMessage.From = new MailAddress(email.From);
   7. emailMessage.To.Add(email.To);
   8. emailMessage.Subject = email.Subject;
   9. emailMessage.Body = email.Body;
   11. await smtp.SendMailAsync(emailMessage);
   12. }
   13. }

5. Test the files by right-clicking on the Index file and open it with a browser. Enter the From, To, Subject, and Body of the email. Then, click the “Send Email” button.
   
   
   

6. Email is received at the “To” address you provided while testing.
