Remarks

Message Availability

This message works regardless whether the caller is connected to the server or offline.

Usage

Pass an instance of this class to the Execute method, which returns an instance of RetrieveRelationshipResponse.

Privileges and Access Rights

To perform this action, the caller must have privileges listed in RetrieveRelationship message privileges.

Notes for Callers

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

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)
