C operates on class instances of session

This article illustrates C# classes that operate on session. Share with you for your reference. The specific analysis is as follows:

This class can set values to arrays or read values to lists of arrays. If you need to, you can use this class to extend the C# class yourself.

using System.Web;

 public static class SessionHelper2
