Namespace:   System.Data
Assembly:  System.Data (in System.Data.dll)

property bool EnforceConstraints {
	bool get();
	void set(bool value);

Property Value

Type: System::Boolean

true if rules are enforced; otherwise false. The default is true.

Exception Condition

One or more constraints cannot be enforced.

Constraints are set at the DataTable level (Constraints property). For more information about creating constraints, see DataTable Constraints.

The following example creates a DataSet with one table, one column, five rows, and one UniqueConstraint. The EnforceConstraints property is set to false and the values of each row are set to the same value. When the EnforceConstraints property is reset to true, a ConstraintException is generated.

No code example is currently available or this language may not be supported.
