You can find the complete sample in the sample code package in the folder SampleCode\CS\GeneralProgramming\LateBound\AssociateDisassociateDE.cs.

备注

Message Availability

无论调用方是连接到服务器还是处于脱机状态，此消息都可正常工作。

Privileges and Access Rights

To perform this action, the caller must have privileges on the entity that is specified in the entityName parameter and access rights on the record that is specified in the entityId parameter. For a list of the required privileges, see Associate Privileges.

Notes for Callers

This method creates multiple associations in one transaction between the record that is specified by the entityId parameter and each record in the relatedEntities parameter for the specified relationship in the relationship parameter.

For a one-to-many relationship, this method sets the ReferencingAttribute in the related record to the value of the entityId.

For a many-to-many relationship, this method creates a record in the intersect table for the relationship, which contains the ID of both the referenced and referencing records. The intersect table name is defined in the IntersectEntityName property for the relationship. You need this when you query for the records. However, you need the relationship name to set the Relationship property. This name is defined in the SchemaName property for the relationship.

For more information about the exceptions that can be thrown when this method is called, see Handle Exceptions in Your Code.

Supported Entities

You can use this method to associate any records that participate in a relationship, including records for custom entities.
