How to use the same info across multiple forms

Question

I am working on my first C# program and have run into a brick wall. I want to be able to set and get variables throughout diferent forms in the same application.

I created a class caleld "data" which contains the following:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Application1
{
    public class data
    {

        public string SearchAirport
        {
            get 
            { 
                return searchairport; 
            }
            set 
            { 
                searchairport = value; 
            }


        }
    }
}

What do I need to put into my forms to be able to use this class??

Right now all I have is:

data.SearchAirport = commandAirport;
string working = data.SearchAirport;

I know I have to add something else to keep from getting the "Error 11 An object reference is required for the non-static field, method, or property 'Sector_Datastore_2._0.data.SearchAirport.get'..." error

Answer 1

data d = new data();

....before those lines

Answer 2

Well, you need to declare searchairport:

public class data
{
    private string searchairport;

    public string SearchAirport
    {
        get 
        { 
            return searchairport; 
        }
        set 
        { 
            searchairport = value; 
        }


    }
}

alternatively, you could let C# do that automatically by using the following code:

public class data
{
    public string SearchAirport
    {
        get;
        set;
    }
}

Answer 3

You are accessing searchAirport statically, and the method itself is not static.

You can either add the static keyword to the SearchAirport method signature or create a data object and then call SearchAirport on that object.

Thank you guys, that got it!

I'd suggest a Service Locator pattern, but I'm afraid it's way too complicated for what the Question-poster wants to achieve.
