The first DataTable you add will be the first one, and so on. What is the issue?

I already use this code
dset.Tables.Add(newDT)

But I want to make sure for this reason I have given this post. Anyway thanks!

Its garunteed to be tables[0] in this case.

I think you answered it. Seems pretty obvious. I think you should post as solution.

Rohan already answered the question. If you want it to be the first Table then add it first. However, I would suggest referencing by name instead of relying on indexing being in a specific order.

You can do this:

C#

myDataSet.Tables["SomeTable"]

instead of

C#

myDataSet.Tables[0];

Then you know you're accessing the right datatable when there are more than one in a dataset and ordering is not important.
