Examples

The following example shows how to use this message. For this sample to work correctly, you must be connected to the server to get an IOrganizationService interface. For the complete sample, see the link later in this topic.



//You can use either the Name or the MetadataId of the relationship.

//Retrieve the One-to-many relationship using the MetadataId.
RetrieveRelationshipRequest retrieveOneToManyRequest =
    new RetrieveRelationshipRequest { MetadataId = _oneToManyRelationshipId };
RetrieveRelationshipResponse retrieveOneToManyResponse =
    (RetrieveRelationshipResponse)_serviceProxy.Execute(retrieveOneToManyRequest);

Console.WriteLine("Retrieved {0} One-to-many relationship by id", retrieveOneToManyResponse.RelationshipMetadata.SchemaName);

//Retrieve the Many-to-many relationship using the Name.
RetrieveRelationshipRequest retrieveManyToManyRequest =
    new RetrieveRelationshipRequest { Name = _manyToManyRelationshipName};
RetrieveRelationshipResponse retrieveManyToManyResponse =
    (RetrieveRelationshipResponse)_serviceProxy.Execute(retrieveManyToManyRequest);

Console.WriteLine("Retrieved {0} Many-to-Many relationship by Name", retrieveManyToManyResponse.RelationshipMetadata.MetadataId);



'You can use either the Name or the MetadataId of the relationship.

'Retrieve the One-to-many relationship using the MetadataId.
Dim retrieveOneToManyRequest As RetrieveRelationshipRequest =
 New RetrieveRelationshipRequest With {.MetadataId = _oneToManyRelationshipId}
Dim retrieveOneToManyResponse As RetrieveRelationshipResponse =
 CType(_serviceProxy.Execute(retrieveOneToManyRequest), RetrieveRelationshipResponse)

Console.WriteLine("Retrieved {0} One-to-many relationship by id",
                  retrieveOneToManyResponse.RelationshipMetadata.SchemaName)

'Retrieve the Many-to-many relationship using the Name.
Dim retrieveManyToManyRequest As RetrieveRelationshipRequest =
 New RetrieveRelationshipRequest With {
  .Name = _manyToManyRelationshipName
 }
Dim retrieveManyToManyResponse As RetrieveRelationshipResponse =
 CType(_serviceProxy.Execute(retrieveManyToManyRequest), RetrieveRelationshipResponse)

Console.WriteLine("Retrieved {0} Many-to-Many relationship by Name",
                  retrieveManyToManyResponse.RelationshipMetadata.MetadataId)
