Hi there,

I am using ASP.Net 2.0 with VB.Net.

I want to define variables. For example I want to create variable of
type TableRow and while defining I don't know how many rows i needed.
So what i want to do in my code:

For i As Integer = 0 To dt.Tables(0).Rows.Count - 1
dim tr_i as New TableRow

' other code.....

Next i

But it will define variable as tr_i...but i want tr_0,
tr_1,tr_2,.........

Is it possible?

Thanks,

SV

It is possible that you are not exactly on the right track. What do you want
to achieve?

This is called an Array. I would suggest to read at least once the language
specification so that you have an idea of what you have at your disposal...

You may want also to explain what you are trying to do (This is a datarow,
not a tablerow, you can browse each row using for each. You already have
this array using dt.Tables(0).Rows(i) etc....)

As others have mentioned, dynamic variables are possible in .NET but are
generally considered to be poor programming practice.

There will almost certainly be much more efficient methods - can you explain
a bit more about what you're trying to do...?

Thanks all for your replies.

I think I was not able to explain you very well. But I tried to do the
things using arrays but didn’t get exactly what I want.
Anyways, I have solved the problem.

I really appreciate your precious replies.
Thanks.

It could help others if you posted the solution you arrived at.
Sharing information like that is the very purpose of these newsgroups.

Can you ?
