3.Add new Button component at the end of the email form and execute (<any>this).sendEmail(this.mailMessage) on Button Click event send-email5.png

4.Run the application to generate Angular and .NET Core apps and add the following code to client/send-email.component.ts and server/SendMailController.cs similar to Invoke custom server-side method article:


import { Component, Injector } from '@angular/core';
import { SendEmailGenerated } from './send-email-generated.component';

// Import HttpClient and HttpParams which are needed to make HTTP calls.
import { HttpClient, HttpHeaders } from '@angular/common/http';
// Import the environment to get the server URL
import { environment } from '../../environments/environment';

  selector: 'send-email',
  templateUrl: './send-email.component.html'
export class SendEmailComponent extends SendEmailGenerated {
  constructor(injector: Injector, private http: HttpClient) {

  sendEmail(mailMessage: any) {
    let headers = new HttpHeaders();

    headers = headers.set('Accept', 'application/json');

    if (mailMessage) {
      headers = headers.set('Content-Type', 'application/json');
    }`http://localhost:5000/api/mail/sendmail`, mailMessage, {
    }).subscribe(result => {
      console.log("Email sent!");



using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;

namespace Sample.Controllers
    public class Email
        public string To { get; set; }
        public string Cc { get; set; }
        public string Subject { get; set; }
        public string Text { get; set; }

    public class MailController : Controller
        public async Task<IActionResult> SendMail([FromBody]Email email)
            var client = new System.Net.Mail.SmtpClient("", 111);
            client.UseDefaultCredentials = false;
            client.EnableSsl = true;

            client.Credentials = new System.Net.NetworkCredential("yourusername", "yourpassword");

            var mailMessage = new System.Net.Mail.MailMessage();
            mailMessage.From = new System.Net.Mail.MailAddress("");


            if (!string.IsNullOrEmpty(email.Cc))

            mailMessage.Body = email.Text;

            mailMessage.Subject = email.Subject;

            mailMessage.BodyEncoding = System.Text.Encoding.UTF8;
            mailMessage.SubjectEncoding = System.Text.Encoding.UTF8;

            await client.SendMailAsync(mailMessage);
