Compile Time DEFINEs in an ASP.NET Web Deployment Project

Question

My envirorment is Visual Studio 2005. My specifically problemis I want to define TRACE.

I have a Web Site Project that send trace messages when run out of the ASP.NET Development Server thanks to defining it in the system.codedom element of the web.config.

When I deploy to IIS, I do so via a web deployment project. So the site is precompiled. Naturally, these entries serve no purpose on a compiled website. My question is how do I define TRACE in the web deployment project.

Answer 1

There is no equivalent to #defines in C#. That said, it sounds like you want to use conditional tracing, which is easily accomplished. If you have diagnostic code throughout your project but want to define it, use the built in trace functionality, for example

System.Diagnostics.Trace.WriteLine("Some debug output");

Then, in your webconfig, you can configure it on/off using

<configuration>
 <system.web>
  <trace enabled="true" requestLimit="40" localOnly="false"/>
 </system.web>
</configuration>
