HttpContext.Current.IsDebuggingEnabled

这对于决定要输出哪些脚本(最小或完整版本)或其他您在开发中可能想要但不是实时的脚本非常有用。

System.Web.VirtualPathUtility

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

If you use web services instead WCF services, you can still use standard .Net membership to enforce authentication and login session behaviour on a set web services similarly to a how you would secure web site with membership forms authentication & without the need for a special session and/or soap headers implementations by simply calling System.Web.Security.FormsAuthentication.SetAuthCookie(userName, false) [after calling Membership.ValidateUser(userName, password) of course] to create cookie in the response as if the user has logged in via a web form. Then you can retrieve this authentication cookie with Response.Cookies[].Value and return it as a string to the user which can be used to authenticate the user in subsequent calls by re-creating the cookie in the Application_BeginRequest by extracting the cookie method call param from the Request.InputStream and re-creating the auth cookie before the membership authenticates the request this way the membership provider gets tricked and will know the request is authenticated and enforce all its rules.

将此cookie返回给用户的示例web方法签名如下: 字符串登录(用户名、密码)

后续web方法调用示例如下: 字符串DoSomething(字符串authcookie，字符串methodParam1,int methodParam2等，等)，你需要提取authcookie(这是从登录方法获得的值)参数从请求。InputStreamis

这也模拟了一个登录会话并调用FormsAuthentication。签出在web方法，如注销(authcookie)将 使用户需要再次登录。

使用configSource拆分配置文件。

你可以在web中使用configSource属性。将配置元素推送到其他.config文件，例如: 而不是:

    <appSettings>
        <add key="webServiceURL" value="https://some/ws.url" />
        <!-- some more keys -->
    </appSettings>

.．.您可以将整个appSettings部分存储在另一个配置文件中。这是新的网络。配置:

    <appSettings configSource="myAppSettings.config" />

myAppSettings。配置文件:

    <appSettings>        
        <add key="webServiceURL" value="https://some/ws.url" />
        <!-- some more keys -->
    </appSettings>

这对于您向客户部署应用程序并且不希望他们干扰web的场景非常有用。配置文件本身，只是希望他们能够改变只是几个设置。
