帮忙看看这个简单的LInQ怎么修改！

[zengjd]

var query1 =
from obj in result
select new
{
obj.ID,
obj.Name,
objary = obj.GetObjary(),
keyObjary = (from o in objary
select new
{
o.ID,
parts = GetParts( o.ID)
}).ToArray()
};


private object GetParts( int id)
{
XXX
}


红色部分有错误，提示“当前上下文中不存在名称objary ，
我可以把obj.GetObjary(),就没有错误了，
可是这么做，导致多调用了obj.GetObjary(),
影响效率，

应该怎么修改呢？

试试这样：【let的使用】
var query1 =
from obj in result
let jary = obj.GetObjary()
select new
{
obj.ID,
obj.Name,
objary = jary ,
keyObjary = (from o in jary
select new
{
o.ID,
parts = GetParts( o.ID)
}).ToArray()
};

                                parts = GetParts( o.ID)
                              }).ToArray()
                };
