You can find the limitations in MSDN but I don't have a link.

From MSDN[^]:

To add rows to a DataTable, you must first use the NewRow method to return a new DataRow object. The NewRow method returns a row with the schema of the DataTable, as it is defined by the table's DataColumnCollection. The maximum number of rows that a DataTable can store is 16,777,216. For more information, see Adding Data to a DataTable.
