2 ways I can think of off top of head:

1) Similar to what you suggest, create a DataTable object, add the columns,
then loop through creating NewRow()s and setting their values.

2) There is an OLE provider that will happily open a CSV file and allow you
to do a "select * " from it, which will result in a dataset. Can't remember
the connection string off top of head, but search google for... hang on...
connectionstrings.com has one ready made:

"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\txtFilesFolder\;Extended
Properties=""text;HDR=Yes;FMT=Delimited"""

The Windows Forms DataGrid relies on data binding to work with its data. A DataSource for use with DataBinding needs to implement one of IList, ITypedList, or IBindingList. So you can use an ArrayList as a valid source (though you need to use "ArrayList" as the MappingName if you want to adjust the style of the grid presentation, or the type name of your collection if you roll your own typesafe list).
However if you are reading a CSV file, I am guessing that you might have something that lends itself well to representation as a table. In that case you could use a DataTable - which you construct on the fly - to hold your values and use that as the DataSource. If your CSV file has multiple tables, then you can use a DataSet to hold your DataTable collection and use that as the DataSource
