Hi Mahmoud,

I don't know if it's possible. The .NET DataSet is completely
different from Delphi's TDataSet. Both have columns, rows, methods and
a lot of similarities but they're now equal. Open VS and Delphi and
compare it. You will see a lot of differences too.

If you're trying to use COM, I think you should not expose your .NET
DataSet directly to Delphi. One option is building a class that has a
private dataset and a method that return dataset's data as an array of
strings or something similar.

I'm not an expert so other people opinion is important.
