table

The DataTable to find.

The index of the DataTable if it is in the collection; otherwise, -1.

Use the IndexOf method to determine the index of a given table.

Before calling IndexOf, you can test for the existence of a table by using the Contains method.

The following example returns the index of each table in a DataTableCollection.

private void GetIndexes ( DataSet ds ) {
   DataTableCollection myTables = ds.Tables;

   // get the index of each table in the collection.
   foreach ( DataTable tbl in myTables ) {
      Response.Write ( myTables.IndexOf ( tbl ) );
   }
}

Private Sub GetIndexes ( ByVal ds As DataSet )
   Dim myTables As DataTableCollection = ds.Tables
   Dim tbl As DataTable
   ' get the index of each table in the collection.
   For Each tbl In myTables
      Response.Write ( myTables.IndexOf ( tbl ) )
   Next
End Sub
