The DataRelationCollection represents the set of DataRelation objects defined for the parent/child tables of a given DataSet. This collection is accessed via the DataSet.Relations property.
Like most data collections in ADO.NET, the DataRelationCollection uses standard collection methods to manage the items in the collection. These include the methods Add, Clear, and Remove.
The collection also includes a Count property to determine how many DataRelation objects are in the collection, and a Contains method to verify whether a specified relation exists in the collection.
