System.Configuration.Configuration

Alberto

Can you tell me how to read and modify a value in the app.config file using
this class?
Thank you very much

Hi,

The online documentation and examples should be more than adequate:

Configuration Class
http://msdn2.microsoft.com/en-us/library/system.configuration.configuration.aspx

If you simply need to read/write data in the appSettings element then you
can use the ConfigurationManager class:

ConfigurationManager Class
http://msdn2.microsoft.com/en-us/library/system.configuration.configurationmanager.aspx

You may also want to check out Application Settings, new to the 2.0
Framework:

Hi!

Funny, i am just dealing with a problem related to this.

I cant access the configuration class somehow...

I use the System.Configuration, but for some reason the
System.Configuration.Configuration is not accessible from the
System.Configuration?!? I do have net framework 2 installed...

Any idea?

Regards
Martin

Hi Martin,

You can't see it or just can't access it? Realize that the Configuration
class has not static method or properties (other than ReferenceEquals,
inherited from Object). It may be the ConfigurationManager class that
you're after.

If you have added a System.Configuration assembly reference to your project,
then I see no reason why the Configuration class wouldn't be visible in the
code editor. You tried a using directive or fully-qualifying the type name
in code?

Also, Configuration is sealed, and so cannot be inherited. If you're trying
to type it after a ":" then Visual Studio may be excluding it from
IntelliSense.

Hi!

I have tried to use the folowing.

* Use System.Configuration;
* System.Configuration.Configuration config = xxxxxx; (xxx = other code)

For some darn reason it just wont come up. if i compile i get an error.

I have made sure i have the latest .NET Framework 2 and that the project
uses the .NET 2 Framework.

Martin

Ill throw in the compiler error as well:

Error 1 The type or namespace name 'Configuration' does not exist in the
namespace 'System.Configuration' (are you missing an assembly reference?)

And the declared line is:

public void OpenFile()
{
System.Configuration.Configuration config;
}

(The last Configuration is underlined by the compiler...)

Martin

Hi Martin,

You're sure that you have referenced the System.Configuration assembly in
your project from the .NET tab?

Try opening the object browser and expand the System.Configuration node.
Can you find the Configuration class in there? (If you can't find the
System.Configuration namespace then the assembly probably isn't referenced
by any of your projects).

Hi Martin,
Isn't all assemblies loaded for Visual Studio to use?
Click to expand...

The C# compiler references mscorlib automatically, by default. Visual
Studio may add some references for you to new projects created by a
particular template. For instance, a new WinForms project will have a
reference to System.Windows.Forms.dll. You have to add any references that
Visual Studio doesn't add for you.
