目前想寫出將此查詢改為LINQ的寫法

SELECT top 1 type.id, type.tw, d.id as did, d.name, d.create_date, d_detail.text, type.is_global
FROM type
left join d ON type.id = d.type_id and d.company_id=1
left join d_detail ON d_detail.d_id = d.id
WHERE type.id = 1
ORDER BY d.id DESC

					UNION
				SELECT top 1 type.id, type.tw, d.id as did, d.name, d.create_date, d_detail.text, type.is_global 
                    FROM type 
                    left join d ON type.id = d.type_id 
                    left join d_detail ON d_detail.d_id = d.id 
                    WHERE type.id = 2
                    

調整後目前為
var q = from c in db.types
join o in db.d on c.id equals o.id
join r in db.d_detail on o.id equals r.d_id
where c.id == 1
orderby o.id

                select new {
                    c.id,
                    c.tw,
                    o.id,
                    o.name,
                    o.company_id,
                    r.text,
                    c.is_global
                };

但select new內的o.id會報錯
錯誤訊息為匿名類型不可有多個同名屬性
研究後推測c.id與o.id衝突
想請問各位大大
LINQ有可以設定別名之類的作法或是其他如何處理該問題之方法嗎?
另外這樣設定與上面SQL設定取之值是否相同呢?
感謝看完
