UniqueConstraint.Equals(Object) UniqueConstraint.Equals(Object) UniqueConstraint.Equals(Object) UniqueConstraint.Equals(Object) Method

Definition

Compares this constraint to a second to determine if both are identical.

public:
 override bool Equals(System::Object ^ key2);
public override bool Equals (object key2);
override this.Equals : obj -> bool
Public Overrides Function Equals (key2 As Object) As Boolean
Parameters
key2
Object Object Object Object

The object to which this UniqueConstraint is compared.

Returns

true, if the contraints are equal; otherwise, false.

Examples

The following example compares two UiqueConstraint objects.

Private Sub CompareConstraints()
    Dim constraintCustomerOrders As UniqueConstraint
    Dim constraintOrderDetails As UniqueConstraint
    Dim relationCustomerOrders As DataRelation
    Dim relationOrderDetails As DataRelation

    ' Get a DataRelation from a DataSet.
    relationCustomerOrders = DataSet1.Relations("CustomerOrders")

    '  Get a constraint.
    constraintCustomerOrders = relationCustomerOrders.ParentKeyConstraint

    ' Get a second relation and constraint.
    relationOrderDetails = DataSet1.Relations("OrderDetails")
    constraintOrderDetails = relationOrderDetails.ParentKeyConstraint

    ' Compare the two.
    Console.WriteLine( _
        constraintCustomerOrders.Equals(constraintOrderDetails).ToString())
 End Sub

Remarks

Two constraints are equal if they constrain the same columns.
