ASP.NET 与 HttpPost 一起发送 email

Question

I'm new to C# and I got a task to make a "Contact us" type of thing on a website.

How can I send an email at the same time when data from a form is being inserted into SQL DB?

This is my post method

[HttpPost]
        public JsonResult Post(Contact con)
        {
            string query = @"
                           insert into dbo.Contact(ContactName,ContactEmail,ContactSubject,ContactMessage,ContactDate)
                           values (@ContactName,@ContactEmail,@ContactSubject,@ContactMessage,@ContactDate)
                            ";

            DataTable table = new DataTable();
            string sqlDataSource = _configuration.GetConnectionString("ContactAppCon");
            SqlDataReader myReader;
            using (SqlConnection myCon = new SqlConnection(sqlDataSource))
            {
                myCon.Open();
                using (SqlCommand myCommand = new SqlCommand(query, myCon))
                {
                    myCommand.Parameters.AddWithValue("@ContactName", con.ContactName);
                    myCommand.Parameters.AddWithValue("@ContactEmail", con.ContactEmail);
                    myCommand.Parameters.AddWithValue("@ContactSubject", con.ContactSubject);
                    myCommand.Parameters.AddWithValue("@ContactMessage", con.ContactMessage);
                    myCommand.Parameters.AddWithValue("@ContactDate", DateTime.Now);
                    myReader = myCommand.ExecuteReader();
                    table.Load(myReader);
                    myReader.Close();
                    myCon.Close();
                }
            }

            return new JsonResult("Added Successfully");
        }

Can I just add some code there, that would get executed together with the query and email would be sent?

You can use following code for sending email.

 [HttpPost]
        public JsonResult Post(Contact con)
        {
            string query = @"
                           insert into dbo.Contact(ContactName,ContactEmail,ContactSubject,ContactMessage,ContactDate)
                           values (@ContactName,@ContactEmail,@ContactSubject,@ContactMessage,@ContactDate)
                            ";
    
            DataTable table = new DataTable();
            string sqlDataSource = _configuration.GetConnectionString("ContactAppCon");
            SqlDataReader myReader;
            using (SqlConnection myCon = new SqlConnection(sqlDataSource))
            {
                myCon.Open();
                using (SqlCommand myCommand = new SqlCommand(query, myCon))
                {
                    myCommand.Parameters.AddWithValue("@ContactName", con.ContactName);
                    myCommand.Parameters.AddWithValue("@ContactEmail", con.ContactEmail);
                    myCommand.Parameters.AddWithValue("@ContactSubject", con.ContactSubject);
                    myCommand.Parameters.AddWithValue("@ContactMessage", con.ContactMessage);
                    myCommand.Parameters.AddWithValue("@ContactDate", DateTime.Now);
                    myReader = myCommand.ExecuteReader();
                    table.Load(myReader);
                    myReader.Close();
                    myCon.Close();
                }
            }
            SendEmail(con.ContactEmail,con.Subject,con.Body);
            return new JsonResult("Added Successfully");
        }
    public void SendEmail(string email,string subject,string Body)
    {
    // Write your logic here..
    }
