What must I do to access my own public method?

I have created folders in my project named Classes, Forms, and Models.

Let's say my project is named ABC, so the folder hierarchy is:

ABC
    Classes
    Forms
    Models

In \Models\, I have a class named ApplicationModel.cs, which contains a public method named GetApplications().

However, when I call that method from elsewhere in the same ABC project, I get, "The name 'GetApplications' does not exist in the current context"

I've added:

using ABC.Models;

to the calling class, but it makes no difference. I right-clicked GetApplications() to hopefully see "Resolve" there, but no go.

What must I do to access my own public method?

Looks like the class is not marked as public.

You class should be 

   namespace ABC 
  {
    namespace Models
    {
        public class ApplicationModel  //class needs to be public is accessed outside the namespace
        {

        }
    }
  }

It is hard to give definitive advice without some code on how you are trying to call that method. I can think of two possible ways:

  • either you are trying to call the method via the ApplicationModel class(ApplicationModel.GetApplications()), in which case you need to declare the method static
  • or you need to call the method on an object, but you are using the type -- in this case declare/create an object of type ApplicationModel and call the method on that object; (e.g. ApplicationModel model = new ApplicationModel(); model.GetApplications();)

It would be helpful to see the definition of GetApplications() and the code that's attempting to call it, but I assume it's either a static or an instance method of the ApplicationModel class. In either case, you may have made your code aware of the namespace of the ApplicationModel class with the using statement, but the method must either be called on the class or an instance of the class, like so:

If GetApplications is a static method, 

var applications = ApplicationModel.GetApplications();

If it's an instance method:

var appModel = new ApplicationModel(); // or, retrieve the instance from elsewhere...

var applications = appModel.GetApplications();

One way or another, you must refer to the class containing GetApplications in order to call it. If this doesn't help you solve the problem, please edit your question to contain the definition of the method, and the calling code.

Sounds like you're using a static function. Did you forget the static keyword?

A static function "runs" from a class, not an object:

public static string[] GetApplications()
