this C# code in VB?

[G Dean Blake]

I have this code snippet in C# that I have to convert to VB

object o = null;
if (mode == PageTrackingMode.ByApplication) {
o = Page.Application[HitsKey];
}
else if (mode == PageTrackingMode.BySession) {
o = Page.Session[HitsKey];
}

In most of the C# code I see that is referring to Session and Application
variables I see that quotes are used i.e. Page.Session["HitsKey"] which
would translate to Page.Session("HitsKey") in VB. But the code above is
using the brackets without the quotes. What does that mean and how would
that translate to VB?
Thanks,
G

Woudln't that simply mean that HitsKey is a string variable or constant
defined someplace else?

Yes, HitsKey must be defined elsewhere. Here's the conversion.

Dim o As Object = Nothing
If mode = PageTrackingMode.ByApplication Then
o = Page.Application(HitsKey)
ElseIf mode = PageTrackingMode.BySession Then
o = Page.Session(HitsKey)
End If

This code is actually inside a servercontrol where there is a property named
HitsKey but also there is code using a session and application variable
named "HitsKey". What I don't understand is why if they simply want to
refer to the property why not just say HitsKey instead of
Page.Session[HitsKey] (I don't know why they chose to name a session
variable and a property by the same name.) It's actually code from a book
on writing servercontrols.

ACK, but not necessarily a string...

You've kinda answered your own question there G.
They want to refer to the session(HitsKey) not the server control property
HitsKey that contains this code.
If they just used HitsKey then they would get a reference to the Propertry
not the session var.

But... if they want to refer to the session variable they should use
Page.Session("HitsKey") with Quotes. if they want to refer to the property
they should just say HitsKey. I have always enclosed my session variables
in quotes when writing in VB. I guess I don't know the meaning when the
quotes are not used. am I making sense?

Sounds like you can refer to your session variable in one of two ways:

Page.Session(HitsKey) or Page.Session("my_session_key") where
"my_session_key" is whatever string value that was assigned as the key.

For both of these to return the same session value then HitsKey must be
defined like so:

Dim HitsKey As String = "my_session_key"

Sounds like they made HitsKey a property value for the server control so
that somebody could set what that text value key should be. As opposed to
hard-coding it in the server control as (for example) "my_session_key".

They are trying to encapsulate the server control and hide all the messy
details. One of those details is the session key's name. But you can't
really fully encapsulate a session variable, because the rest of the program
still has access to your session and not just through your server control.

Am I making sense? Probably not. :^)
