Convert List into Dataset in C#

I saw an existing tutorial on this here https://www.c-sharpcorner.com/blogs/converting-collection-to-dataset1 .

Any specific reason you want to convert a list into a DataSet? You can do pretty much everything with List<> what yoiu can do with DataSet. The DataSet is supposed to represent multiple columns and rows, table view, while List represents a list of objects.
