tableName

The name of 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 a named table in a DataTableCollection.

private void GetIndexes ( DataSet ds ) {
   DataTableCollection myTables = ds.Tables;
   // get the index of the table named "Authors", if it exists.
   if ( myTables.Contains ( "Authors" ) ) {
      Response.Write ( myTables.IndexOf ( "Authors" ) );
   }
}

Private Sub GetIndexes ( ByVal ds As DataSet )
   Dim myTables As DataTableCollection = ds.Tables
   ' get the index of the table named "Authors", if it exists.
   If myTables.Contains ( "Authors" ) Then
      Response.Write ( myTables.IndexOf ( "Authors" ) )
   End If
End Sub
