Formo allows you to use your configuration file as a dynamic object. Turn your web.config or application settings into a rich, dynamic object.
Given you have a few of the following settings in your app.config file, you can new up a Configuration object and call those settings directly through a property.
<appSettings>
<add key="RetryAttempts" value="5" />
<add key="ApplicationBuildDate" value="11/4/1999 6:23 AM" />
</appSettings>dynamic config = new Configuration();
var retryAttempts1 = config.RetryAttempts; // returns 5 as a string
var retryAttempts2 = config.RetryAttempts(10); // returns 5 if found in config, else 10
var retryAttempts3 = config.RetryAttempts(userInput, 10); // returns 5 if it exists in config, else userInput if not null, else 10Both of the values userInput and 10 will be ignored if the value has already been set in your file.
The Configuration class also has the ability to call dynamic methods with type arguments. (I know, right?!) This lets you call your property and cast it to the type of your choice.
dynamic config = new Configuration();
var appBuildDate = config.ApplicationBuildDate<DateTime>();If you have dates in your settings file that need to be bound to a specific culture, you can do this on creation of the Configuration class.
dynamic config = new Configuration(new CultureInfo("de"));You can also use Formo to bind settings values to properties on an object:
given:
<appSettings>
<add key="SessionTimeout" value="20" />
<add key="WebsiteSettingsSiteTitle" value="Cat Facts" />
</appSettings>and...
public class WebsiteSettings
{
public int SessionTimeout { get; set; }
public string SiteTitle { get; set; }
}then...
dynamic config = new Configuration();
var settings = config.Bind<WebsiteSettings>();resulting in...
settings.SessionTimeout = 20;
settings.SiteTitle = "Cat Facts";You can use Formo on Configuration Sections
<configuration>
<configSections>
<section name="customSection" type="System.Configuration.NameValueSectionHandler"/>
</configSections>
<customSection>
<add key="ApplicationBuildDate" value="11/4/1999 6:23 AM" />
</customSection>
<appSettings>
</appSettings>
</configuration>This still works from the previous example:
dynamic config = new Configuration("customSection");
var appBuildDate = config.ApplicationBuildDate<DateTime>();Remark the name of the section to load on the Configuration creation.
So far the only suported sections are based on System.Configuration.NameValueSectionHandler.
The Property Binding feature also works on sections.
You can also access connection strings by name like so:
dynamic config = new Configuration();
var devConnection = config.ConnectionString.Development;
var prodConnection = config.ConnectionString.Production;Given that there are connection strings in the configuration that matches the following config:
<?xml version="1.0"?>
<configuration>
<!-- stuff -->
<connectionStrings>
<add connectionString="<some dev connection...>" name="Development"/>
<add connectionString="<the production connection...>" name="Production"/>
</connectionStrings>
<!-- more stuff -->
</configuration>when using Formo to automatically bind settings values to properties on an object as described here, connection strings are automatically bound if the object contains properties of type "ConnectionStringSettings" :
given:
<appSettings>
<add key="SessionTimeout" value="20" />
<add key="WebsiteSettingsSiteTitle" value="Cat Facts" />
</appSettings>
<!-- stuff -->
<connectionStrings>
<add connectionString="<some dev connection...>" name="Development"/>
<add connectionString="<the production connection...>" name="Production"/>
</connectionStrings>
<!-- more stuff -->and...
public class WebsiteSettings
{
public int SessionTimeout { get; set; }
public string SiteTitle { get; set; }
public ConnectionStringSettings Development { get; set; }
public ConnectionStringSettings Production { get; set; }
}then...
dynamic config = new Configuration();
var settings = config.Bind<WebsiteSettings>();resulting in...
settings.SessionTimeout = 20;
settings.SiteTitle = "Cat Facts";
settings.Development = "<some dev connection...>";
settings.Production = "<the production connection...>";Sometimes, you may need to access a value that contains special characters in the key and cannot be referenced like a property of function. When this is the case, you can still get the value by the string representation, like so:
dynamic config = new Configuration();
var specialValue = config.Get("Some:Value!");To install Formo, please use NuGet (Formo NuGet Page):
