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.

/// <summary>
/// Determines whether two tables are eligible to participate in a one-to-many relationship
/// </summary>
/// <param name="service">Authenticated IOrganizationService instance</param>
/// <param name="referencedEntityLogicalName">Primary table</param>
/// <param name="referencingEntityLogicalName">Referencing table</param>
/// <returns>Whether the tables are eligble.</returns>
public static bool CheckEligibilityForOneToManyRelationship(IOrganizationService service,
      string referencedEntityLogicalName,
      string referencingEntityLogicalName)
{
      //Checks whether the specified table can be the primary table in one-to-many
      //relationship.
      CanBeReferencedRequest canBeReferencedRequest = new()
      {
         EntityName = referencedEntityLogicalName
      };

      var canBeReferencedResponse =
         (CanBeReferencedResponse)service.Execute(canBeReferencedRequest);

      //Checks whether the specified table can be the referencing table in one-to-many
      //relationship.
      CanBeReferencingRequest canBeReferencingRequest = new()
      {
         EntityName = referencingEntityLogicalName
      };

      CanBeReferencingResponse canBeReferencingResponse =
         (CanBeReferencingResponse)service.Execute(canBeReferencingRequest);

      return canBeReferencedResponse.CanBeReferenced && canBeReferencingResponse.CanBeReferencing;
}
