C# - AppSettings Fallback / Default Value?

Sep 21, 2010

For each appSetting I use, I want to specify a value that will be returned if the specified key isn't found in the appSettings. I was about to create a class to manage this, but I'm thinking this functionality is probably already in the .NET Framework somewhere?

Is there a NameValueCollection/Hash/etc-type class in .NET that will let me specify a key and a fallback/default value -- and return either the key's value, or the specified value?

If there is, I could put the appSettings into an object of that type before calling into it (from various places).

Configuration :: Can't Access AppSettings From Web.config - ConfigurationSettings.AppSettings Is Empty?

Jun 12, 2010

i have stored settings in the AppSettings section of the web.config file.

I'm trying to access these settings via System.Configuration.ConfigurationSettings.AppSettings, but the AppSettingsCollection is empty. So I can't access this settings.

The strange thing is that this is working on my development machine, but is failing on the production machine. Previous versions of the web application have also worked on the production machine. I'm not aware of any modifications that could couse this.

I have also tried using ConfigurationManager and WebConfigurationManager without success.

C# - AppSettings Vs ApplicationSettings. AppSettings Outdated?

Feb 28, 2010

I've got some question about two ways to save settings in the web.config.

Appsettings:

Look in web.config
<appSettings>
<add key="key1" value="value1"/>
<add key="key2" value="value2"/>
</appSettings>

Usage in code-behind:

ConfigurationManager.AppSettings["key1"];
ApplicationSettings/ Properties (autogenerated by using the 'properties'-tab in the project)
Look in web.config
<applicationSettings>
<Projectname.Properties.Settings>
<setting name="Testenvironment" serializeAs="String">
<value>True</value>
</setting>
</Projectname.Properties.Settings>
</applicationSettings>

Usage:

Properties.Settings.Default.Testenvironment

So, what the difference between these two storage possibilities of settings in the web.config? As far as I can see, a downside of the appSettings is that you have modify the web.config yourself and the appSettings are not strong tiped, where as the applicationSettings are. Both are replaceable with in a web deployment project.As far as I am concerned, there is no use for appSettings. Am I missing something here? Which is the historically seen older one?

MVC Custom Route Fallback?

Jun 5, 2010

I'm wondering if it is possibile to customize routing in a way that all requests are evaluated by a piece of code, redirected to the relevant controller if a match is found or passed to next rout in list if not found.

sample request:
/my coolpage/another one

the code searches and determine that the right controller for this is Page, action is "list" and id is "123" and so redirects

another request:
/products/list/5

code finds no match al passes it back to next route that knows how to handle it...

Web Forms :: Custom ResourceProvider With A Fallback For Standard .NET Localization Mechanism?

May 7, 2010

I wrote my own custom ResourceProvider in order to move localization management to DB instead using standard resx files.The provider works fine, but now (after having bought a third part components for UI) I need to implement a fallback to standard ASP.NET localization mechanism from my own provider since these controls has been already localized from the author and are packaged with resx files.So what I would like to do, is keep the actual mechanism for all the resources except for the resoucers related to this controls.I'm able to distinct when a resource is belong to external components, so what I need is how to invoke for this resource the standard location management.

Web Forms :: Use ConfigurationManager.AppSettings For SRC?

Aug 25, 2010

I've set an AppSetting key for my root directory in my web.config file and now I'm going back through my site and changing all link and resources to use this key. Then If the domain ever changes I can just change one line of code and not worry about links breaking. I'm not quite sure however how to use this when I register my header and footer user controls.

How To Improve CM.AppSettings References

Mar 3, 2010

ASP.NET 3.5 Classes throughout our solution referenced ConfigurationManater.AppSettings[""] to get appSettings (from web.config).

We decided we weren't happy with that. Folks were mistyping appSetting key names in code (which compiled fine), and it was cumbersome to track usages. And then there's the duplicated strings throughout the codebase as you reference the same appSettings all over the place.

So, we decided that only one class would be allowed to reference the ConfigurationManager, and the rest of the solution would reference that class when it needed the value of a certain appSetting. ConfigurationManater.AppSettings[""] was static, so we exposed a bunch of static read-only properties off of our single Settings class.

[Code].....

And now we're injecting the ISettings instance as a dependency of the objects which use settings values (the class/interface are in a project that everyone can reference without problems).

In places where we can't inject an existing instance (e.g. Global.asax), we construct a new instance into a static field.

Given all of that, what would you recommend we change, and why?

ASP MVC - ConfigurationManager Cannot Find Appsettings?

Oct 27, 2010

I am using MS Test to test one of my controller's actions. This method uses the ConfigurationManger to read appSettigns from the web.config. For some reason ConfigurationMangager is not able to find the appsettings.In NUNIT I would just make sure to add a copy of the webconfig file to the test project so that it is available when running in that context. However this is not working for me.

Getting AppSettings Values From Web.config In Javascript?

Apr 30, 2010

[Code]....

</script>

In the span's onclick handler i wrote "javascript: alert(getAppSetting('ftpuser'));" for testing, and built some alerts into the function. The first alert returns [object]. That's nice, i thought. The second alert returned 0. That's strange, because the web.config has exactly 1 of this node. So i guess that the function doesn't actually load the correct document. Has anyone done something similar ? When i don't suppy a full path, doesn't javascript assume that it should look for the file in the virtual directory of the current web application where the web.config is ?

Access To Web.config Attributes (not AppSettings)?

Mar 23, 2011

given that I can add various addributes to the stock membership provider I assume I can do the same with my own provider implementation.

<add name="MyMembershipProvider" type="Portal.Infrastructure.MyMembershipProvider"
enablePasswordRetrieval="false"
enablePasswordReset="true"
requiresQuestionAndAnswer="true"
[...] />

My question now: How do I access these values in the code? I understand that the ConfigurationManager can be used to access key value pairs in the appSettings section but this is different.

Reading And Writting Keys To Appsettings In WebConfigEditor?

Mar 2, 2011

I am just a beginner in the world of programming and I need to work on the following requirement:

My project contains web.config file and an external appSettings file. I am making a WebConfig Editor that has options to Read AppSettings key from web.config and external appSetting file to display them on webPage. Also, I am allowing user to delete any key by clicking on Remove button. Moreover, user can also update any key's value by clicking on update button.Or he can also insert new key by clicking on Add New Key button.

The key issue I am facing is that whenfever I try to add a new key , it gets inserted into web.config file as expected , but at the same time it adds all the keys present in external appSettings file into web.config ( which is abrupt behavior). How to stop this migration of keys from external appSettings file to web.config on any key's update / delete/ add function?

Put Custom AppSettings Web.config Data Into The ApplicationState?

Mar 7, 2011

I've got some custom values in the AppSettings, in my web.config file.

These values get checked upon every Request.

eg.

So if every request checks the web.config file for the value of this key, would be be smart to put this into the Application cache (eg. via the global.asax) instead of checking this value EVERY request?

I'm assuming that when we read a value from the AppSettings, the website does a physical read of the web.config file? or is this information also all read into Memory when the website starts up and all references to any appSettings information is just an inmemory read .. not a disk I/O read?
