我想使用PLINQ在产品和类别之间执行内部联接。但是我不确定是否应该为这两个集合调用AsParallel方法。

// PLINQ  - Option 1
jointTables =     from c in Homework02.categories.AsParallel()
                  join p in Homework02.productList on c.Name equals p.Category
                  select new { Category = c, Product = p };

// PLINQ  - Option 2
jointTables = from c in Homework02.categories.AsParallel()
              join p in Homework02.productList.AsParallel() on c.Name equals p.Category
              select new { Category = c, Product = p };
