Name

InvalidConstraintException

Synopsis

This exception is thrown when incorrectly attempting to create or access a DataRelation object. For example, if you attempt to remove a DataRelation when a corresponding ForeignKeyConstraint exists on a table, or if you try to specify DataRelation parent-and-child columns with incompatible data types or in tables from different DataSet objects, this exception is thrown.
