        //how can I get all the contacts here
        foreach (Entity contact in Account.Contact.Entities)//????
        {
            Entity activityParty = new Entity("activityparty");
            activityParty["partyid"] = new EntityReference("??", e.Id);

            if (toList.Any(t => t.GetAttributeValue<EntityReference>("partyid").Id == e.Id)) continue;

            toList.Add(activityParty);
        }

        return toList;
    }

您可以在联系人实体中找到客户键“ parentcustomerid”。 您可以按以下帐户ID获取联系人集合。

  private EntityCollection getContactByAccountId(IOrganizationService service, Guid accountId)
    {
        QueryExpression query = new QueryExpression("contact");
        query.ColumnSet = new ColumnSet(new string[] { "contactid", "fullname" });
        query.Criteria.AddCondition(new ConditionExpression("parentcustomerid", ConditionOperator.Equal, accountId))
        return service.RetrieveMultiple(query);
    }
