Cet exemple montre comment associer un contact à trois enregistrements de compte à l’aide de la méthode IOrganizationService.Associate. Il indique également comment utiliser la méthode IOrganizationService.Disassociate.

Exemple


// Associate the accounts to the contact record.

// Create a collection of the entities that will be 
// associated to the contact.
EntityReferenceCollection relatedEntities = new EntityReferenceCollection();
relatedEntities.Add(new EntityReference(Account.EntityLogicalName, _account1Id));
relatedEntities.Add(new EntityReference(Account.EntityLogicalName, _account2Id));
relatedEntities.Add(new EntityReference(Account.EntityLogicalName, _account3Id));

// Create an object that defines the relationship between the contact and account.
Relationship relationship = new Relationship("account_primary_contact");


//Associate the contact with the 3 accounts.
_service.Associate(Contact.EntityLogicalName, _contactId, relationship,
    relatedEntities);

Console.WriteLine("The entities have been associated.");

//Disassociate the records.
_service.Disassociate(Contact.EntityLogicalName, _contactId, relationship,
    relatedEntities);
