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 instance.

This example uses the Account_Tasks one-to-many relationship by default, but you can use the roleprivileges_association to try a many-to-many relationship.

/// <summary>
/// Retrieves a table relationship definition by name
/// </summary>
/// <param name="service">Authenticated IOrganizationService instance</param>
static void RetrieveRelationshipExample(IOrganizationService service) {

    // Example One-to-many
    string schemaName = "Account_Tasks";

    // Example many-to-many
    //string schemaName = "roleprivileges_association";

    RetrieveRelationshipRequest request = new() { 
          Name = schemaName,
          // MetadataId isn't used in this example
    };

    var response = (RetrieveRelationshipResponse)service.Execute(request);

    // Write the output for both types of relationships

    switch (response.RelationshipMetadata.RelationshipType)
    {
        case Microsoft.Xrm.Sdk.Metadata.RelationshipType.OneToManyRelationship:

            // Cast the RelationshipMetadata
            var one2N = (OneToManyRelationshipMetadata)response.RelationshipMetadata;

            Console.WriteLine($"One: {one2N.ReferencedEntity}" +
                $".{one2N.ReferencedAttribute}");
            Console.WriteLine($"Many: {one2N.ReferencingEntity}" +
                $".{one2N.ReferencingAttribute}");

            break;

        case Microsoft.Xrm.Sdk.Metadata.RelationshipType.ManyToManyRelationship:

            // Cast the RelationshipMetadata
            var n2N = (ManyToManyRelationshipMetadata)response.RelationshipMetadata;

            Console.WriteLine($"Between {n2N.Entity1LogicalName} " +
                $"and {n2N.Entity2LogicalName} ");
            Console.WriteLine($"Intersect Table: {n2N.IntersectEntityName} ");

            break;

        default:
            // This should not occur.
            break;
    }
}

Output:

Using Account_Tasks:

One: account.accountid
Many: task.regardingobjectid

Using roleprivileges_association:

Between privilege and role
Intersect Table: roleprivileges
