Web.config and environment variables. Please help!

[Guest]

Hi, all:
I would like to know one thing: Is it possible to access an environment
variable (like PATH) from web.config file? Something like this:
<appSettings>
<add key="name" value="%Environment{PATH}\Shared"></add>
</appSettings>

or

<add key="name" value="${PATH}\Shared"></add>
or anything else?

I think it´s not possible the access to system or environment variables from
inside web.config, but I need to be absolutely sure.

Thanks a lot for your help!

No, you would have to translate these in your code that read in the value.

No.

But what you can do is encapsulate that logic inside a function:

public sealed ConfigurationManager
{
private ConfigurationManager(){}
public static string Path
{
get
{
return Configuration.AppSettings["name"].Replace("{PATH}",
Environment.GetEnvironmentVariable("Path");
}
}
}

as an example...

Yes of course, but what value does that add? Why not just interrogate the
environment variable when required...?

It helps encapsulate the logic. A lot of people would have done the
replacement each time on all of their pages. Apologies with assuming you
didn't know this...you never know what people do and don't know
