我如何加入参数化存储过程与LINQ表C＃

Question

已经尝试了本

var Result = from a in db.ViewEntity // view 
let b = db.sp_Get_log(a.id) // parametrized stored procedure returns rowset 
select new LogFields 
{ 
    UniqueID = a.ID, 
    WorkFlow_Status = a.Document_Status, 
    Creator = a.Creator, 
    Duration = a.Duration, 
    Approver = b.LastOrDefault().Action_User // this 
}; 

但我收到此错误，请帮助。

LINQ实体无法识别方法System.Data.Objects.ObjectResult1 [db.Agent.sp_Get_log_Fields] sp_Get_log（System.String）”方法，和这种方法不能被翻译成表达商店。

首先得到的结果在内存中，然后调用存储过程是这样的：

var ResultList = db.ViewEntity.ToList(); 

var Result = from a in ResultList 
let b = db.sp_Get_log(a.id) // parametrized store procedure returns rowset 
select new LogFields 
{ 
    UniqueID = a.ID, 
    WorkFlow_Status = a.Document_Status, 
    Creator = a.Creator, 
    Duration = a.Duration, 
    Approver = b.LastOrDefault().Action_User // this 
};
