Associate and Disassociate Records using C# Code - Dynamics CRM/365

Hi Everyone,

This might be a old one but somehow I could not get this piece code very easily.

Here is the piece of C# code for Associating and Dissociating two records with N:N relationship.

Associate
string relationshipName = "<<RelationShipName>>";
Relationship relationship = new Relationship(relationshipName);
EntityReferenceCollection relatedEntities = new EntityReferenceCollection();
EntityReference secondaryEntity = new EntityReference("SecondEntitySchemaName", GUIDOfSecondEntityRecord);
relatedEntities.Add(secondaryEntity);
crmService.Associate("FirstEntitySchemaName", GUIDOfFirstEntityRecord, relationship, relatedEntities);

Disassociate
string relationshipName = "<<RelationShipName>>";
Relationship relationship = new Relationship(relationshipName);
EntityReferenceCollection relatedEntities = new EntityReferenceCollection();
EntityReference secondaryEntity = new EntityReference("SecondEntitySchemaName", GUIDOfSecondEntityRecord);
relatedEntities.Add(secondaryEntity);crmService. Disassociate ("FirstEntitySchemaName", GUIDOfFirstEntityRecord, relationship, relatedEntities);


Hope this helps.
