How can i execute C# code in Asp .Net Website

Question

i am new to C# .NET. I want to know how i can execute a .cs program in an .aspx website buttonClick.

Lets say i want to execute the below code in the buttonclick.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication3
{
class Program
{
    static void Main(string[] args)
    {
        int a = 10;
        int b = 20;
        int c = a + b;

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 Button1_Click(object sender, EventArgs e)
{

}
}

Microsoft does not recommend calling an .exe from a Web application as w3wp.exe runs in a sandboxed environment for security reasons and hence any thread/task/process that it launches is not the same as it would be when you launch it yourself and hence may not work as expected.

Is is possible , but not recommended.
