table

The DataTableMapping to find.

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

IList.IndexOf

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

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

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

private void GetIndexes ( DataAdapter myAdapter ) {
   DataTableMappingCollection myTables = myAdapter.TableMappings;

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

Private Sub GetIndexes ( ByVal myAdapter As DataAdapter )
   Dim myTables As DataTableMappingCollection = myAdapter.TableMappings
   Dim myTable As DataTableMapping
   ' get the index of each table in the collection.
   For Each myTable In myTables
      Response.Write ( myTables.IndexOf ( myTable ) )
   Next
End Sub
