Do i need to convert the session variable to str开发者_如何学编程ing if i wanna follow "good coding practices"?

Ex:

IMO, you should be using

Option Strict On
Option Explicit On

at all times, it makes the compiler yell at you when you cast implicitly or use undeclared identifiers.

Yes as a good practice and if you want to assign to a new variable:

Dim userName As String = Session("UserName")

Otherwise you can use it directly:

Print Session("UserName")

Note that value "Sally" (wrapped in quotes) is a string.
