web.config中appsettings元素的'file'属性。

指定包含自定义应用程序配置设置的外部文件的相对路径。

如果你的应用程序设置很少，需要在不同的环境(prod)上进行修改，这是一个很好的选择。

因为网络的任何变化。配置文件会导致应用程序重新启动，使用单独的文件允许用户修改appSettings部分中的值，而不会导致应用程序重新启动。单独文件的内容与Web中的appSettings部分合并。配置文件。

包含在ASP中。Net 3.5 sp1:

customErrors现在支持“redirectMode”属性，值为“ResponseRewrite”。显示错误页面而不改变URL。 表单标记现在识别操作属性。非常适合在使用URL重写时使用

Page对象上的ClientScript属性。

当我将xmlDocument()转储到标签中并使用它的xsl转换显示时，我认为这很整洁。

我使用的一件事是在多个版本的VB, VBScript和VB中工作。NET将记录集值转换为字符串，以消除对NULL或空白的多次测试。例如修剪(rsData(“字段名”)。值& " ") 在整数值的情况下，这将是:CLng("0" & Trim(rsData("FieldName")。值& " "))

这是最好的一个。把它加到你的网里。配置更快的编译。这是3.5SP1后通过这个QFE。

<compilation optimizeCompilations="true">

Quick summary: we are introducing a new optimizeCompilations switch in ASP.NET that can greatly improve the compilation speed in some scenarios. There are some catches, so read on for more details. This switch is currently available as a QFE for 3.5SP1, and will be part of VS 2010. The ASP.NET compilation system takes a very conservative approach which causes it to wipe out any previous work that it has done any time a ‘top level’ file changes. ‘Top level’ files include anything in bin and App_Code, as well as global.asax. While this works fine for small apps, it becomes nearly unusable for very large apps. E.g. a customer was running into a case where it was taking 10 minutes to refresh a page after making any change to a ‘bin’ assembly. To ease the pain, we added an ‘optimized’ compilation mode which takes a much less conservative approach to recompilation.
