Description:

This project illustrates a very simple website for sell different types of mobile devices by request. So in short, after the customer fills all information to complete purchasing procedure, he/she will receive confirmation message which contains the most of information that have been entered, moreover, the encrypted information using RSA Algorithm to his /her e-mail that has already been entered in buy page. Figures and the script code show the project is fully.

The Code Asp.Net (C#):

Default Page’s Code:

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void ButtonBuy1_Click(object sender, EventArgs e) { Session.Add("Phone1", LabelPhone1.Text); Session.Add("Price1", LabelPrice1.Text); // Redirect to Buy.aspx page. Server.Transfer("Buy.aspx"); } protected void ButtonBuy2_Click(object sender, EventArgs e) { Session.Add("Phone2", LabelPhone2.Text); Session.Add("Price2", LabelPrice2.Text); // Redirect to Buy.aspx page. Server.Transfer("Buy.aspx"); } }

Contact Us Page’s Code:
