how to assign session object to user control

[Guest]

Hi all,
I have the following code, without option Strict on, it seems work OK, but
when option strict is on. I have a problem for the assignment.

Dim ctrlarr(5) As PeopleInfo 'poepleinfo is user control in project
Dim i As Integer
If Not Session("ctrlarr") Is Nothing Then
ctrlarr = Session("ctrlarr")
End If
It says option strict on disallows implicit conversion from 'system.object'
to '1-dimensional array of subway.peopleinfo'
I guess I would have the same problem when I assign
Session("ctrlarr")=ctrlarry in the first page if I turn on option Strict.
What should I do in this case?

You have to cast to specific type before assiging it back.
In c# it will be ctrlarr = (subway.peopleinfo)Session("ctrlarr")
Not sure what VB cast looks like

Hi GS,
I did
ctrlarr = CType(Session("ctrlarr"), PeopleInfo())
It didn't complain anything.
I haven't run the code, guess it's OK.
Thank you.

Hi Betty,

I suggest always explicitly cast object to their actual type since that'll
also help improve performance and avoid problem.

If there're any other problem, please feel free to post here.
