Share variables between projects

Question

I have a solution with some projects. One of this projects is the one I\'ve defined as main, also his class has a main Method.

Inside this class, I\'ve defined some

Answer 1

In Project B, Add a reference to Project A and add a using Cobra statement to Project B wherever you want to access something from the Cobra (Project A) namespace.

Answer 2

Based on your comments to other answers it sounds like your problem is really that you have a circular dependency which you need to break. Generally the way to do that is to factor out an interface and place it in a third project that both other projects can reference so instead of

class Foo //foo lives in project 1 (depends on project 2)
{
    public Bar GetNewBar()
    {
        return new Bar(this);
    }
    public void DoSomething(){}
}

public class Bar //bar lives in project 2 (depends on project 1 -- cant do this)
{
    public Bar(Foo parent){}
}

you have

class Foo: IFoo //foo lives in project 1 (depends on project 2 and 3)
{
    public Bar GetNewBar()
    {
        return new Bar(this);
    }
    public void DoSomething(){}
}

public class Bar //bar lives in project 2 (depends on project 3)
{
    public Bar(IFoo parent){}
}

public interface IFoo //IFoo lives in project 3 (depends on nothing)
{
    void DoSomething();
}

Answer 3

@Manu,

It is possible through reflection. The following is the solution to your problem.

You have created 2 projects

Project B -- having namespace "Net", class "HttpHandler"

Project A -- having namespace "cobra", static class "Program" and having reference of Project B

Now your problem is you need to access the class "Program" in Project B without giving reference of Project A to Project B because then the solution will not build as it will give cyclic reference error.

Check out the following

Project A

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

namespace Cobra
{
    public static class Program
    {
        public static int A { get; set; }//Getter/Setter is important else "GetProperties" will not be able to detect it
        public static int B { get; set; }

        static void Main(string[] args)
        {
            HttpHandler obj = new HttpHandler();
            obj.ProcessRequest(typeof(Program));
        }
    }
}

Project B

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

namespace Net
{
    public class HttpHandler : IHttpHandler 
    {
        public void ProcessRequest(Type cobraType)
        {
            int a, b;
            foreach (var item in cobraType.GetProperties(BindingFlags.Public | BindingFlags.Static | BindingFlags.FlattenHierarchy))
            {
                if (item.Name == "A")
                    a = (int)item.GetValue(null, null);//Since it is a static class pass null
                else if (item.Name == "B")
                    b = (int)item.GetValue(null, null);
            }
        }
    }
}

Hope this is of some help.

Samar

Answer 4

You need to add a using directive at the top of project B's file:

using Cobra;

And add project A as a reference in project B.

Answer 5

You need to add a reference to Project A to project B - right click on the project node in the solution explorer, select references, then projects then Project A.

You will then have access to all the types in Project A.
