The following example gets each Constraint from the ConstraintCollection.

NOTE: This example uses one of the overloaded versions of the Item property ( ConstraintCollection indexer ). For other examples that may be available, see the individual overload topics.

private void GetConstraint ( DataTable myTable ) {

   for ( int i = 0; i < myTable.Constraints.Count; i++ ) {
      Response.Write ( myTable.Constraints [ ].ConstraintName );
      Response.Write ( myTable.Constraints [ ].GetType ( ) );
   }
}

Private Sub GetConstraint ( myTable As DataTable )
   Dim i As Integer
   For i = 0 To myTable.Constraints.Count - 1
      Response.Write ( myTable.Constraints ( i ).ConstraintName )
      Response.Write ( myTable.Constraints ( i ).GetType ( ) )
   Next i
End Sub
