很多学习Linq的朋友肯定有自己所不同的方法，考虑这个问题我所想到的是
用Take(),Skip(),TakeWhile(),SkipUntil()中的方法来实现
首先看Take()是否可用
Take方法的作用是从结果中取固定数量的值，
MydbDataContext mydb=new MydbDataContext("server=.;database=mydb");
var query=from p in mydb.Products
orderby p.id descending
select p;//取出Products中所用的项按降序排列
如果直接用 take()
var q=query.take(n) 这样只能取出前条n记录，但是还是让我们看到了分页的曙光，还是还有个skip吗，skip可以取出除去满足条件的剩下的记录。如果我们要把数据以每页 pagesize的数量来进行分页，很简单，很skip(pagersize*pagenum)然后在剩下的记录中take(pagesize)不就得到 了想要的数据了么。
varq=query.skip(pagesize*pagenum).take(pagesize) 就这么简单。
希望朋友们提供更好的方法来进行分页，同时对这个方法的优劣性，进行批评指导附上运行时生成的SQL(感谢：紫色阴影 、Boler Guo ）
