Application and session variables work similarly, each having a dictionary of objects. Keys identify each object in the dictionary. The keys are normally text strings that give a name to each object in the dictionary. For example, I might have a user ID object and I might name it UserId.

// C# 
Session[“UserId”] = 12; 

' VB 
Session(“UserId”) = 12

 // C# Session[“UserName”] = “John Doe”; ' VB Session(“UserName”) = “John ...
