Is there a difference between DataTable.Clear and DataTable.Rows.Clear?

Question

I recall there is a difference between some methods/properties called directly on the DataTable class, and the identically named methods/properties on the DataTable.Rows pro

Answer 1

There is no difference between them. DataRowCollection.Clear() calls Table.Clear()

Table.Clear() checks that the table can be cleared (constraints can prevent this), removes the rows and rebuilds any indexes.
