System.Data (system.data.dll)

class

This exception is thrown if you attempt an action that violates a constraint or if you try to apply a constraint to a DataTable that contains rows that violate it. For example, you might try to create more than one row with the same value in a unique column or a child record that references a nonexistent parent.
