dynamics-crm - 将契约(Contract)行添加到契约(Contract) CRM 2011

Question

我希望有人能帮助我进一步，因为我真的很困在这里。我试图从创建后插件向我的契约(Contract)实体添加契约(Contract)行。我的代码:

Guid c_Id = (Guid)entity.Attributes["contractid"];
DateTime start = (DateTime)entity["activeon"];
DateTime end = (DateTime)entity["expireson"];
Money money = new Money();
money.Value = 0;


//Set Instance for Contract Line 
Entity ContractLine = new Entity();
ContractLine.LogicalName = "contractdetail";

//Create Contract Line for the Contract
ContractLine["title"] = "PLUGIN FIRED";
ContractLine["activeon"] = start;
ContractLine["expireson"] = end;
ContractLine["totalallotments"] = 1;
//ContractLine["customerid"] = entity["customerid"];  
//ContractLine["productid"] = entity["productid"];
ContractLine["price"] = money;
ContractLine["contractid"] = c_Id;

service.Create(ContractLine);

出于某种原因，我收到了“属性:contractid 不能设置为 NULL”的错误，这真的很奇怪，因为它实际上确实获得了 contractid 的 GUID，因为我在另一个实体的另一个字段上检查了它。如果有人能在这里帮助我，我将不胜感激。谢谢。

Answer 1

应ContractLine["contractid"] = c_Id;是 ContractLine["contractid"] = new EntityReference("contract", c_Id); ?

c_Id 也应该是 EntityReference 而不是 GUID？
