Adding to the previous questions I have asked:

How I can execute C# code using Roslyn in ASP.Net web form?


I want to know about Roslyn API ( execute ).
how should its input should be and waht's the output.

using System.Web.UI.WebControls;
using System.ComponentModel;
using Roslyn.Scripting;
using Roslyn.Scripting.CSharp;
using Roslyn.Compilers;
using Roslyn.Compilers.CSharp;
using System.IO;

namespace WebApplication2
{
    public partial class _Default : Page
    {

        //private object result = new object();


        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button_Click(object sender, EventArgs e)
        {
            String code = TextBox3.Text;
            var ScriptEngine = new ScriptEngine();
            var session = ScriptEngine.CreateSession();
            try
            {
                session.AddReference("System");
                session.AddReference("System.core");
                object result = session.Execute(code);
                TextBox2.Text = result.ToString();
            }
            catch (System.NullReferenceException err)
            {
                TextBox2.Text = err.Message;
            }

           



        }


    }
}
