.NET ShortCut

the 2 comparison operators i am talking about here are : "Is" and "="

actually , the existence of both of them returns to the old VB6 . coz for old classes we used to have 3 property accessors : "Let , get and set " and the old mistake "default properties "

so we can say simply in VB6 :

Label1 = "User Name : "   which means        Let Label1 = "User Name : " 

and we can also say

Label1 = new Label()         which means       Set Label1 = new label()

so in the past if we say :

if  label1 = "User name"         then 'do something      this is a using of the opreator "="

but if we say       if Label1 = label2 then 'do something     this invokes the "Is" operator .

we no more have "set" in VB.NET , so some people think "Is" should have been removed from the language as well and have only 1 comparison .

but it is due to simplicity and more readability (from my point of view) that they still keep the "Is" so we still have reference comaprison as well as value comparison or else we are going to write it as the other languages     Object.ReferenceEquals(a,b)   . so using "Is" is much more readable and cleaner ..
