Remarks

The CreateRelationship method creates a relationship between the origin object and the destination object specified in the parameters.  By default, when a relationship class is created, a relationship is created between the objects with corresponding primary and foreign key values.  When subsequently using CreateRelationship, remember that this operation will write a value into the foreign key field.  Therefore, in the case of 1:1 and 1:M relationship classes, it is possible that you could overwrite, and therefore delete, an existing relationship.

This method should be called within an edit session.
