Definition
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Returns an enumeration of all the related ends managed by the relationship manager.
public:
System::Collections::Generic::IEnumerable<System::Data::Objects::DataClasses::IRelatedEnd ^> ^ GetAllRelatedEnds();
public System.Collections.Generic.IEnumerable<System.Data.Objects.DataClasses.IRelatedEnd> GetAllRelatedEnds ();
member this.GetAllRelatedEnds : unit -> seq<System.Data.Objects.DataClasses.IRelatedEnd>
Public Function GetAllRelatedEnds () As IEnumerable(Of IRelatedEnd)
Public Iterator Function GetAllRelatedEnds () As IEnumerable(Of IRelatedEnd)
Returns
An IEnumerable<T> of objects that implement IRelatedEnd. An empty enumeration is returned when the relationships have not yet been populated.
Examples
This example adds new SalesOrderHeader
entities to the Contact
entity. Then it gets all related ends from the Contact
entity and displays relationship name, source role name, and target role name for each related end,
using (AdventureWorksEntities context =
new AdventureWorksEntities())
{
Contact contact = new Contact();
// Create a new SalesOrderHeader.
SalesOrderHeader newSalesOrder1 = new SalesOrderHeader();
// Add SalesOrderHeader to the Contact.
contact.SalesOrderHeaders.Add(newSalesOrder1);
// Create another SalesOrderHeader.
SalesOrderHeader newSalesOrder2 = new SalesOrderHeader();
// Add SalesOrderHeader to the Contact.
contact.SalesOrderHeaders.Add(newSalesOrder2);
// Get all related ends
IEnumerable<IRelatedEnd> relEnds =
((IEntityWithRelationships)contact).RelationshipManager
.GetAllRelatedEnds();
foreach (IRelatedEnd relEnd in relEnds)
{
Console.WriteLine("Relationship Name: {0}", relEnd.RelationshipName);
Console.WriteLine("Source Role Name: {0}", relEnd.SourceRoleName);
Console.WriteLine("Target Role Name: {0}", relEnd.TargetRoleName);
}
}
Remarks
The GetAllRelatedEnds method returns an enumeration of EntityCollection<TEntity> and EntityReference<TEntity> objects. EntityCollection<TEntity> and EntityReference<TEntity> are concrete types that derive from RelatedEnd. The RelatedEnd abstract class implements the IRelatedEnd interface.
