ConfigurationPropertyAttribute.IsRequired Property

[=?Utf-8?B?Q2h1Y2sgUA==?=]

I was creating a Custom Configuration section in my web.config.

I noticed that if I set a property like:
[ConfigurationProperty("EmailAuthorizationFailures" , IsRequired = true)]

<MySection
EmailAuthorizationFailures="true"
/>
and I neglected to put the entire MySection in the web.config. I don't get
an error. Additionally if I actually read the section using
GetConfig("MySection") it comes back full of values (DefaultValue or
ValueType defaults ). I thought it would be NULL.

I would like to throw an exception if the user forgets to put in the
section in the web.config.
Is their a way to test for the missing section?

thanks,

Hi Chuck,

As for the "how to test the missing of a configuration section in .net
config file", I think it a good question. However, based on my research,
the current .NET configuration settings model doesn't provide support of
detecting the existence of a configuration section automatically(only the
detection of a sub section properrty is supported). This limitation is due
to the following design of the configuration section processing mechanism:

** When .net application runs, it will not always load all the
configuration settings at one time or at the startup time. The loading of
each configuration section is on-demand and may occur at different time.
Thus, it won't be convenient to check all the potential configsection's
existence.

** So far <configSections><sectionelement only support the definition of
the scope and modify-behavior of the registered section, haven't provided
setting to control the existence detection

For your scenario, if you do need to take care of some certain custom
configuration's existence, I think you may consider manually use the
configuration API to query the certain section in code or use XML API to
perform xml query against the app.config file.

Thanks,
I'll think I will use a little hack.
Create a setting. IhaveBeenSpecified default =false.
When I read the settings in code if it is false, I'll throw an exception.

Thanks for your reply Chuck,

Yes, the method you mentioned should be a good trick to help perform such
detection. Thanks for sharing it with us.

BTW, I also think this is a reasonable feature and recommend you submit it
to our product feedback site:
