Be aware that any changes to web.config while the web app is running will
cause it to recycle, thereby tearing down all currently active sessions...

Thanx Mark,

I didn't know that.... Better to store the data somewhere else then....

Re: get/set data web.config

Very much so.

In addition, it can be impossible to update web.config from your app
(definitely in 1.x), as the app locks the file. Unless you are truly working
with configuration elements, I would store in an XML file or a database.

In .NET 2.0, you can specify additional configs, that you can alter while
the site is running, if these truly are "dynamic" config elements, but I
would consider metadata tables in a database first.

The values you mention seem pretty static, so a one-time configuration
at install is all that is needed. In that case web.config is fine.
Values that have to be changed frequently are best kept elsewhere (some
custom config file, database)

Mark,

Do you think reading and writing to a resource file using a shared class is
a good solution ?

Thanx

John

Re: get/set data web.config


You can try this trick:


<?xml version = "1.0" encoding = "utf-8" ?>

<configuratio n>

<appSettings file="CustomApp Settings.config " >

</appSettings>

</configuration>



Contents of CustomAppSettin gs.config

--start, do not include this line
<appSettings>

<add key="demokey1" value="demovalu e1" />

</appSettings>

--end, do not include this line


And this is Peter's great writeup about it.

http://www.eggheadcafe.com/tutorials/aspnet/e54f2d32-72c4-4d2b-b180-c1f564b41f85/some-aspnet-20-configur.aspx

I don't think the webapp is recycled with this method. I haven't
specifically tested it.

...

Don't forget to add POST BUILD events if you doing non asp.net stuff
(winforms, console apps, etc).
(this comment for future readers more than you, since you're doing asp.net)

It largely depends what you're trying to do and why you're trying to do
it...

If the values that you want to read out of web.config are unlikely to change
very often, I'd probably read them into Application variables at
Application_Sta rt and then refer to them from there thereafter...

However, if they are likely to change quite often, then web.config probably
isn't the best place to start from anyway...
