I can’t get a variable from another namespace

Question

A project is Webapplication and the other one is like Console:

"Projectste" Nomedasolution Structure below:

1. Business(Pasta)

   2. Businessdal(project)
      3. Arquivodal.Cs

2. Console(project)

   3. Business.Cs

//Project Businessdal, Arquivodal.Cs

using Console; //Isto não funciona, já tentei com e sem.

namespace BusinessDAL
{
    public class ArquivoDAL
    {   

       public static string caminhos(){  



           string valor =  Console.Caminho; // Nâo funciona 
           string valor =  Console.Business.Caminho; // Nâo funciona 
           string valor =  Caminho; // Nâo funciona 

           return valor;

      }
    }
}

//Console Project, Business.Cs file

namespace Console
{
  public class Business
    {
        public static string Caminho = ConfigurationManager.AppSettings.Get("Path").ToString();

       //Isto já foi testado também
        public static string NomeDoProduto
         {
             get { return NomeDoProduto; }
             set { NomeDoProduto = Caminho ; }
         }


    }

}

Error message: the name 'Console' does not exist in the Current context

Answer 1

I created two projects: Consoleapp1 and Consoleapp2.

What you should do is add the reference to ConsoleApp2 in the project ConsoleApp1 to access the variables of ConsoleApp2 in the project ConsoleApp1.

For that do the following:

1. Add project 2 reference to project 1

Right click on References, and select Add Reference:

Within Projects, select Solution and mark the project you want to reference and click OK:

2. Access the desired variable

Once done, within project 1 you can already access the project 2 variable as follows:

  namespace ConsoleApp1
  {
      public class Program
      {
          static void Main(string[] args)
          {
              var teste = ConsoleApp2.Teste.Caminho;            
          }
      }
  }

Answer 2

Using Console.Business.Caminho works. I created a project without setting anything up and it worked. I just made some changes to simplify the compilation, but if your code is the one posted in the question there is no way to go wrong.

I would change the name Console because if you’re using a using System will give conflict with the class Console contained in that namespace. Of course, using the full name of what you are accessing works, as in the code below. In this case it is possible to even delete the using Console`.

Since you’re on the same project, you don’t have to do anything else. If you’re in another project and you’re in the same solution, you should have a reference to this project, unless you’ve corrupted something. If it is a separate site project (not shown in the question) then you need add a design reference to her (visually supported).

namespace BusinessDAL {
    public class ArquivoDAL {   
        string valor =  Console.Business.Caminho;
        static void Main() => System.Console.WriteLine("Hello, World!"); //só p/ compilar
    }
}
