[英]Invalid 'where' condition. An entity member is invoking an invalid property or method
[英]Linq Error : Invalid 'where' condition. An entity member is invoking an invalid property or method
我在CRM2013
運行Linq查詢並拋出錯誤:
無效的“ where”條件。 實體成員正在調用無效的屬性或方法。
我的代碼如下
var conntionRecord1Id = (from connectionBase in orgServiceContext.CreateQuery("connection")
where connectionBase["record1roleid"] != null
select connectionBase["record1id"]
).Distinct();
var query = from opportunity in orgServiceContext.CreateQuery("opportunity")
where conntionRecord1Id.Contains(opportunity["opportunityid"])
orderby opportunity["createdon"] ascending
select new
{
Topic = opportunity.Attributes.Contains("name") == true ? opportunity["name"] : null,
OpportunityId = opportunity.Attributes.Contains("opportunityid") == true ? opportunity["opportunityid"] : null,
PostalCode = opportunity.Attributes.Contains("new_address_postalcode") == true ? opportunity["new_address_postalcode"] : null,
};
錯誤在第二個查詢中引發。
where子句的左側必須是屬性名稱,而右側必須是值。
這是查詢中的問題行:
// lhs must be something from the entity
where conntionRecord1Id.Contains(opportunity["opportunityid"])
安迪·邁耶斯(Andy Meyers)在這里有一個很好的答案: https : //stackoverflow.com/a/15720786/1817350
使用ConditionOperator.In的QueryExpression可能更合適: https : //stackoverflow.com/a/21093122/1817350
