Hi,
You can use below c# code:
string entity1 = “raj_bike”;
string entity2 = “raj_bond”;
string relationshipEntityName = “raj_bike_bond”;
QueryExpression query = new QueryExpression(entity1);
query.ColumnSet = new ColumnSet(true);
LinkEntity linkEntity1 = new LinkEntity(entity1, relationshipEntityName, “raj_bikeid”, “{Entity 1 Primary key field (i.e.,raj_bikeid)}“, JoinOperator.Inner);
LinkEntity linkEntity2 = new LinkEntity(relationshipEntityName, entity2, “raj_bondid”, “{Entity 2 Primary key field (i.e.,raj_bondid)}“, JoinOperator.Inner);
linkEntity1.LinkEntities.Add(linkEntity2);
query.LinkEntities.Add(linkEntity1);
// Add condition to match the Bike name with “Honda”
linkEntity2.LinkCriteria = new FilterExpression();
linkEntity2.LinkCriteria.AddCondition(new ConditionExpression(“raj_bikename”, ConditionOperator.Equal, “Honda”));
EntityCollection collRecords = service.RetrieveMultiple(query);
