The DataTableCollection contains all the DataTable objects for a particular DataSet. To access the DataTableCollection of a DataSet, use the Tables property.

The DataTableCollection uses methods such as Add, Clear, and Remove to manage the items in the collection.

Use the Contains method to determine whether a particular table (specified by either index or name) is in the collection.

To navigate from one table to another, use the ChildRelations or ParentRelations property of the DataTable to access its collection of DataRelation objects. You can also use the Relations property to navigate through the parent/child relationships of the DataTables in a particular DataSet collection.

The first procedure in this example retrieves the DataTableCollection of a DataSet and prints the value of each column, in each row, of each table. The second procedure creates a new DataTable with two columns, and adds it to the DataTableCollection.

No code example is currently available or this language may not be supported.
