aspx_beginners thread: Option Strict Error

Message #1 by "Alvin Ling" <alvin.ling@i...> on Mon, 28 Jan 2002 14:27:41 -0500

I'm setting a session variable via Session_OnStart() in my global.asax



Sub Session_OnStart()



	Session("foo") = "bar"



End Sub



But when I test for it on a page:



If Session("foo") = "bar" Then...



I get the following error:



"BC32013: Option Strict On disallows operands of type Object for

operator '='. Use the 'Is' operator to test for object identity."





I've verified that the Session("foo") does evaluate to a "String" via

TypeName()... help?

Doesn't "foo" have to be in brackets ["foo"] rather than parentheses

("foo")?

In C# an index string for any kind of collection is ["indexstring"] but in

VB isn't it still ("indexstring")?

I've found the problem - possibly a .NET vs VB issue?



Even though TypeName(Session("foo")) evaluates to a String type,

apparently .NET doesn't think so.  I ended up using the .NET conversion

to solve the comparison issue.



	If Session("foo").ToString() = "bar" Then



works fine.



Can someone explain this discrepancy?

I think because it stores the session as an Object  same thing is true

in Java

It's easy:



Session("foo") return type is object



Session("foo").ToString() return type is string
