RelationshipManager.GetAllRelatedEnds RelationshipManager.GetAllRelatedEnds RelationshipManager.GetAllRelatedEnds RelationshipManager.GetAllRelatedEnds Method


Returns an enumeration of all the related ends managed by the relationship manager.

 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 Iterator Function GetAllRelatedEnds () As IEnumerable(Of IRelatedEnd)


An IEnumerable<T> of objects that implement IRelatedEnd. An empty enumeration is returned when the relationships have not yet been populated.


The example in this topic is based on the AdventureWorks Sales Model. The 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.

    // Create another SalesOrderHeader.
    SalesOrderHeader newSalesOrder2 = new SalesOrderHeader();
    // Add SalesOrderHeader to the Contact.

    // Get all related ends
    IEnumerable<IRelatedEnd> relEnds =

    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);
Using context As New AdventureWorksEntities()
    Dim contact As New Contact()

    ' Create a new SalesOrderHeader. 
    Dim newSalesOrder1 As New SalesOrderHeader()
    ' Add SalesOrderHeader to the Contact. 

    ' Create another SalesOrderHeader. 
    Dim newSalesOrder2 As New SalesOrderHeader()
    ' Add SalesOrderHeader to the Contact. 

    ' Get all related ends 
    Dim relEnds As IEnumerable(Of IRelatedEnd) = DirectCast(contact, IEntityWithRelationships).RelationshipManager.GetAllRelatedEnds()

    For Each relEnd As IRelatedEnd 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)
End Using


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.
