[VB2008] How to replace lines in a textfile?

Hi,

I'm pretty new with VB, especialy with 2008 Express :-p So i need your
help...

I have a text file containing:

    VERSION 3
    ADDEDVERSION 5
    OPTION_GUILD_RECRUITMENT_CHANNEL AUTO
    CHANNELS
    guild 1 3
    dutchworld 1 4
    WorldTrade 1 5
    GMhelp 1 6
    END
    ZONECHANNELS 16777216
    COLORS
    SAY 255 255 255
    ....
    ....

And i want to replace the part between CHANNELS and END
I allready found a way to read those lines and change it in the way i want
and put it in an array ( Dim channel_names(0 To 10) As String )

Now i want to replace those 4 lines with my array.

Does anyone has an idea to do this?
Or can anyone give me some hints or examples?

Thanks,
Maurice

Put 'em in a List(Of String) and you can remove and add items using the Add,
AddRange and RemoveAt methods.

Hi Armin,

a StringCollection could do the same, oder?

We don't need generic class when a specialiced class already
exists. ;-)

Thx. There are so many possibilites nowadays that not all of them come to my
mind immediatelly. :-)

Though, a StringCollection is internally implemented as an Arraylist, so
type casting has to be done each time an Item is returned. That's why I'd
prefer the List(Of String).
