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.
