我怎样才能在实体框架中知道视图列的来源

Question

我需要在Entity Framework中了解视图的来源（我需要显示它们）
例如：
    CRMEntity crm = new CRMEntity（）; crm有一个fullTable视图 这是它的脚本：

create view [dbo].[FullTable]
as
select c.iCustomerId,c.id,sum(p.iPoints) sumPoints ,
a.nvCity,a.nvNeighberwood,a.nvStreet,a.iHouseNum,a.nvEnterance,a.iFloor,a.nvNote
from tbl_Customer c 
join Point p on p.iCustomerId=c.iCustomerId 
join tbl_Address a on a.iAddressId=c.iAddressId 
group by p.iCustomerId,c.id,c.iCustomerId,c.nvCellolar,c.nvFirstName,c.nvLastName,c.nvPhone,
a.nvCity,a.nvNeighberwood,a.nvStreet,a.iHouseNum,a.nvEnterance,a.iFloor,a.nvNote

并查看computedColumns视图，这是它的脚本：

create view [dbo].[computedColumns]
as
select a.iAddressId+a.iAddressId cmp1,STR(a.nvCity,0,5) cmp2,333 cmp3,a.iFloor+1 cmp5 from tbl_Address a

（所有选项均来自表格）
我想知道每个列的来源

代表computedColumns：

cmp1->tbl_Address.iAddressId 
cmp2->tbl_Address.nvCity
cmp3->null
cmp5 ->tbl_Address.iFloor

代表FullTable：

iCustomerId->tbl_Customer.iCustomerId
id->tbl_Customer.id 
sumPoints ->Point .sumPoints 
and Etc
