The following example removes a Constraint from a ConstraintCollection after testing for its presence with the Contains method, and whether it can be removed with the CanRemove method.

NOTE: This example uses one of the overloaded versions of Remove. For other examples that may be available, see the individual overload topics.

private void RemoveConstraint ( ConstraintCollection myConstraints, 
      Constraint myConstraint ) {
   try {
      if ( myConstraints.Contains ( myConstraint.ConstraintName ) ) {
         if ( myConstraints.CanRemove ( myConstraint ) ) {
            myConstraints.Remove ( myConstraint.ConstraintName );
         }
      }
   }
   catch ( Exception myException ) {
      Response.Write ( myException.Message );
   }
}

Private Sub RemoveConstraint ( myConstraints As ConstraintCollection, _
      myConstraint As Constraint )
   Try
      If myConstraints.Contains ( myConstraint.ConstraintName ) Then
         If myConstraints.CanRemove ( myConstraint ) Then
            myConstraints.Remove ( myConstraint.ConstraintName )
         End If
      End If

   Catch myException As Exception
      Response.Write ( myException.Message )
   End Try
