以移植到ASP.NET 2.0上 (或者已经内嵌在ASP.NET 2.0中)

1 ASP.NET 2.0 把一些代码进行了封装打包,所以相比1.0相同功能减少了很多代码.
2 同时支持代码分离和页面嵌入服务器端代码两种模式,以前1.0版本,.NET提示帮助只有在分离的代码文件,无法在页面嵌入服务器端代码获得帮助提示,
3 代码和设计界面切换的时候,2.0支持光标定位.这个我比较喜欢

9．把你在学习过程中做过的demo发一个给我，或者把你做过的demo组合在一个项目中发给我

1、override与重载的区别
2、.net的错误处理机制是什么
3、C＃中接口和类的异同
4、DataReader和DataSet的异同

Override用来重写父类的方法，重载使用相同名的方法或操作符拥有不同类型的参数

.net错误处理机制采用try->catch->finally结构，发生错误时，层层上抛，直到找到匹配的Catch为止。

接口和类都是类，不同的事，接口只包含方法或属性的声明，不包含具体实现方法的代码，接口可以实现多继承，而类只能是单继承，继承接口的类必须实现接口中声明的方法或属性。接口主要定义一种规范，统一调用方法，在大型项目中接口正发挥日益重要的作用。

DataReader用于读取数据，DataSet用于在内存中保存数据。

重载与覆盖的区别
1、方法的覆盖是子类和父类之间的关系，是垂直关系；方法的重载是同一个类中方法之间的关系，是水平关系。
2、覆盖只能由一个方法，或只能由一对方法产生关系；方法的重载是多个方法之间的关系。
3、覆盖要求参数列表相同；重载要求参数列表不同。
4、覆盖关系中，调用那个方法体，是根据对象的类型（对象对应存储空间类型）来决定；重载关系，是根据调用时的实参表与形参表来选择方法体的。

4、DataReader和DataSet的异同
DataReader和DataSet最大的区别在于,DataReader使用时始终占用SqlConnection,在线操作数据库..任何对SqlConnection的操作都会引发DataReader的异常..因为DataReader每次只在内存中加载一条数据,所以占用的内存是很小的..因为DataReader的特殊性和高性能.所以DataReader是只进的..你读了第一条后就不能再去读取第一条了..
DataSet则是将数据一次性加载在内存中.抛弃数据库连接..读取完毕即放弃数据库连接..因为DataSet将数据全部加载在内存中.所以比较消耗内存...但是确比DataReader要灵活..可以动态的添加行,列,数据.对数据库进行回传更新操作...

1 ?:
2 装箱
3 3种
4 const成员都是static所以应该去掉static
5 －123
6 要同时修改Equale和GetHash() ? 重载了"==" 就必须重载 "!="
7 delegate
8 不可被继承
9 System.Web.UI.UserControl
10 [serializable]
11 gC
12 abstract override 是不可以一起修饰
13 不可以，不可以
14 case():不行 default;
15 可以

1 Using 引入一个名子空间，或在使用了一个对像后自动调用其IDespose，New 实例化一个对

像，或修饰一个方法，表此方法完全重写此方法，
2 X=1,Y=0
3 x=1,y=2
4 最大区别一个是引用类型，一个是值类型 默认成员访问为public是另外一个区别

A while back, I posted a list of ASP.NET Interview Questions. Conventional wisdom was split, with about half the folks saying I was nuts and that it was a list of trivia. The others said basically "Ya, those are good. I'd probably have to look a few up." To me, that's the right response.

Certainly I wasn't trying to boil all of .NET Software Development down to a few simple "trivia" questions. However, I WAS trying to get folks thinking. I believe that really good ASP.NET (and for that matter, WinForms) is a little [read: lot] more than just draging a control onto a designer and hoping for the best. A good race driver knows his car - what it can do and what it can't.

So, here's another list...a greatly expanded list, for your consumption (with attribution). I wrote this on a plane last week on the way from Boise to Portland. I tried to take into consideration the concerns that my lists contain unreasonable trivia. I tried to make a list that was organized by section. If you've never down ASP.NET, you obviously won't know all the ASP.NET section. If you're an indenpendant consultant, you may never come upon some of these concepts. However, ever question here has come up more than once in the last 4 years of my time at Corillian. So, knowing groking these questions may not make you a good or bad developer, but it WILL save you time when problems arise.
