注解

类提供一种以编程方式访问和修改配置文件trace的内容的方法。 TraceSectionThe TraceSection class provides a way to programmatically access and modify the content of the configuration file trace section. Trace 节配置 ASP.NET 跟踪功能, 并控制如何收集、存储和显示跟踪结果。The trace section configures the ASP.NET trace functionality and controls how trace results are gathered, stored, and displayed.

启用跟踪后, 每个页面请求会生成跟踪消息, 这些消息可以追加到页面输出或存储在应用程序跟踪日志中。When tracing is enabled, each page request generates trace messages that can be appended to the page output or stored in an application trace log. 您可以使用 ASP.NET 跟踪查看器 (trace.axd) 查看跟踪日志的内容。You can use the ASP.NET trace viewer (Trace.axd) to view the contents of the trace log.

备注

Machine.config 文件和 web.config 文件中配置层次结构的部分允许使用元素。The element is allowed in the section of the configuration hierarchy in the Machine.config file and the Web.config files. 不允许在 Web 子目录的配置文件中使用。It is not allowed in configuration files of Web subdirectories.
