Send Email using Gmail SMTP server - ASP.NET

Send Email using Gmail SMTP server-ASP.NET What is an SMTP server? (pronounced as separate letters) Short for S imple M ail T ransfer P rotocol, a protocol for sending e-mail messages between servers. Most e-mail systems that send mail over the Internet use SMTP to send messages from one server to another; the messages can then be retrieved with an e-mail client using either POP or IMAP. In addition, SMTP is generally used to send messages from a mail client to a mail server. This is why you need to specify both the POP or IMAP server and the SMTP server when you configure your e-mail application. Let's see one example in ASP.NET 2.0 (Web Application) In WebMailSend.aspx.cs file You have to import this namespace for MailMessage. using System.Net.Mail; protected void btnSend_Click( object sender, EventArgs e) { try { MailMessage mail = new MailMessage(); mail.IsBodyHtml = true ; mail.To.Add(txtEmail.Text); mail.Subject = txtSubject.Text; mail....

Introduction to ASP.Net MVC

Image
Back to Home Model-View-Controller (MVC) is a software architecture pattern. Originally formulated in the late 1970s by Trygve Reenskaug as part of the Smalltalk, MVC architecture works on code reusability and separation of concerns. It was originally developed for desktop Then adapted for internet applications. The Model is the application object, the View is UI presentation, and the Controller defines the way the user reacts to user input from UI. MODEL: - Set of classes that describe the data we are working with - Rules for how the data can be changed and manipulated - May contain data validation rules - Often encapsulate data stored in a database as well as the code used to manipulate the data Most likely a Data Access Layer of some kind VIEW: - Defines how the application’s user interface (UI) will be displayed - Support master views (layouts)  - Support sub-views (partial views or controls) - Web: Template to dynamically generate HTML CONTR...
