问题描述
以下是我所谈论的一个例子 ：
asp.net采取的是一个非常简单，强大和灵活的
概念，http请求/响应与html进行演示
并将其变成一个荒谬的过于复杂的kludge
导致问题多于它通过尝试将b $ b变为平面，事件驱动来解决。范例
例如：
这里是一个html图片标签
< img src =" Image.gif" />
它有一些额外的属性，如高度，宽度，边框
现在看看相同元素的asp.net文档（如下）
它永远不会结束
如果你看看这些asp.net新闻组你实际上将会看到人们提出的问题，例如我如何设置src属性
的HtmlImage对象？与asp.net
然后是物业访问的长描述
和watch out; 不要在错误的时间做
确保你......
API意味着在那里包装复杂的代码和
使其易于处理
这是一个REVERSE API它需要一些简单的事情
an < IMG />标记并将其变成复杂的东西
这会浪费人们的时间和精力，无论如何都没有任何好处。
" DataBinding" - piffle - 愚蠢的陈述性，不灵活的垃圾
" UserControls" - 平坦无意义，不灵活地重新发明一个方法
带有一个代码块（它甚至不能回调到包含
页面而没有头痛）
" CustomControls" - 好极了！我们可以创造我们自己无意义的偏差 -
哦只是每个类只有一种渲染方法！
i明白在asp.net 2.0中微软已经认为我们值得付出
的母版页 - 哦，我的上帝 - 我一直这样做已经
自aspv1.0以来它被称为asp包含页面的代码块和
回调
这是为谁写的？
如果你不能查询数据库并写出一些html字符串
你有什么可以吗？
" viewstate" - 哦，是的，我真的需要帮助 - 不是！
C＃很棒
..NET框架摇滚
ASP.NET发生了什么？
它可能真的很好

Here is an example of what I am talking about:
asp.net takes what is a very simple, powerful and flexible
concept, http request/response with html for presentation
and turns it into a ridiculously over-complicated kludge
which causes way more problems than it solves by attempting
to turn it into a flat, "event-driven" paradigm
for example:
here is an html image tag
<img src="Image.gif"/>
it has a few extra attributes such as height, width, border
now look at the asp.net documentation for the SAME element (below)
it is never ending
if you look in these asp.net newsgroups you will actually
see people asking questions like "how do i set the src property
of an HtmlImage object?" with asp.net
and then long descriptions of property accesses
and "watch outs" "don''t do it at the wrong time"
"make sure you ..."
APIs are meant to be there to wrap up complex code and
make it simple to handle
this is a REVERSE API it takes something as simple as
an <img/> tag and turns it into something complicated
which wastes peoples time and energy for no benefit whatsoever.
"DataBinding" - piffle - stupid declarative, inflexible rubbish
"UserControls" - flat pointless, inflexible re-invention of a method
with a codeblock (it can''t even callback to the containing
page without a big headache)
"CustomControls" - great! we can create our own pointless aberrations -
oh yes one render method per class only!
i understand that in asp.net 2.0 microsoft has deemed us worthy
of "master pages" - oh my god - i''ve been doing that already
since aspv1.0 its called an asp include page with codeblocks and
callbacks
just who is this written for?
if you can''t query a database and write out some html strings
what can you do?
"viewstate" - oh yes i really needed help with that - not!
C# is fantastic
..NET Framework rocks
what happened to ASP.NET?
it could have been really good
instead its a bad joke foisted on

推荐答案
ASP.NET可以轻松编写WYSIWYG应用程序，并且可以轻松实现$ /
处理控制事件。
如果那不是您使用的模型，使用IDE并编写
应用程序可能会比较困难只是WYSIWYG的东西。但是，它不会比过去更困难，因为你可以只做
确切的事情！
ASP.NET的强大功能在于它的面向对象性质，你可以用它来做很多的事情
。实际上，这可以使大量的事情变得更容易。
VS.NET IDE不适合创建复杂的UI。我想大多数人
会同意这个。
但是，考虑到大多数ASP，是人们使用Response.Write发出
HTML，数据绑定看起来对我来说是一个相当不错的改进。
我认为大多数有ASP.NET问题的人都是那些习惯于
使用不同的技术以不同的方式做事，并且有麻烦将他们的想法转移到使用不同的模型来编写
应用程序。
嘿，如果你不喜欢它，没有人说你必须使用它。写下
您认为最好的技术。

ASP.NET makes it easy to write WYSIWYG applications, and makes it easy to
handle control events.
If that is not the model you are using, that using the IDE and writing your
application may be more difficult then just the WYSIWYG stuff. But, it won''t
be any more difficult then it was in the past, since you can just do the
exact kind of thing!
ASP.NET''s power is in its object oriented nature, and you can do quite a lot
with that. In fact, that can make tons and tons of things easier.
The VS.NET IDE is not suited for creating complex UIs. I think most people
will agree on this.
But, considering that most of ASP, is people using Response.Write to emit
HTML, databinding looks like a pretty good improvement to me.
I think most people who have trouble with ASP.NET, are those who are used to
doing things a different way using a different technology, and are having
trouble shifting their thinking into using a different model for writing
applications.
And hey, if you don''t like it, no one says you have to use it. Write in
whatever technology you feel is best.

Here is an example of what I am talking about:
asp.net takes what is a very simple, powerful and flexible
concept, http request/response with html for presentation
and turns it into a ridiculously over-complicated kludge
which causes way more problems than it solves by attempting
to turn it into a flat, "event-driven" paradigm
for example:
here is an html image tag
<img src="Image.gif"/>
it has a few extra attributes such as height, width, border
now look at the asp.net documentation for the SAME element (below)
it is never ending
if you look in these asp.net newsgroups you will actually
see people asking questions like "how do i set the src property
of an HtmlImage object?" with asp.net
and then long descriptions of property accesses
and "watch outs" "don''t do it at the wrong time"
"make sure you ..."
APIs are meant to be there to wrap up complex code and
make it simple to handle
this is a REVERSE API it takes something as simple as
an <img/> tag and turns it into something complicated
which wastes peoples time and energy for no benefit whatsoever.
"DataBinding" - piffle - stupid declarative, inflexible rubbish
"UserControls" - flat pointless, inflexible re-invention of a method
with a codeblock (it can''t even callback to the containing
page without a big headache)
"CustomControls" - great! we can create our own pointless aberrations -
oh yes one render method per class only!
i understand that in asp.net 2.0 microsoft has deemed us worthy
of "master pages" - oh my god - i''ve been doing that already
since aspv1.0 its called an asp include page with codeblocks and
callbacks
just who is this written for?
if you can''t query a database and write out some html strings
what can you do?
"viewstate" - oh yes i really needed help with that - not!
C# is fantastic
..NET Framework rocks
what happened to ASP.NET?
it could have been really good
instead its a bad joke foisted on
us professionals by dumbo muppets
