1、無參數查詢
var?model?= db.Database.SqlQuery<UserInfo>("select* from UserInfoes ").ToList();

2、有參查詢
var model?= db.Database.SqlQuery<UserInfo>("select* from UserInfoes where id=@ID ",new SqlParameter("@ID",id)).ToList();

3、結合linq查詢

var model?= (from p in db.userinfo.SqlQuery("select * from UserInfoes where id=@ID", new SqlParameter("@ID", 1)) select p).ToList();

4：EF原始查詢單獨表

model = db.userinfo.OrderByDescending(a => a.ID).Skip(10 * (當前頁 - 1)).Take(10).ToList();

5，EF 執行存儲過程或delete 刪除語句

SqlParameter[] para = new SqlParameter[] {?
new SqlParameter("@ID",id)
};
db.Database.ExecuteSqlCommand("delete UserInfoes ?where id=@ID", para);

存儲過程 刪除，有幾個參數，存儲后面要帶幾個參數以逗號分隔

SqlParameter[] para = new SqlParameter[] {?
new SqlParameter("@ID",id)
};
db.Database.ExecuteSqlCommand("sp_Userinfos_deleteByID @ID", para);
