Here my connection string in Abstract class, how can I access my connection string?

```
public abstract class Connection
{
    public SqlConnection sqlConn = null;

    public SqlConnection GetConnection
    {
        get { return sqlConn;}
        set { value = sqlConn; }
    }

    public Connection()
    {
        string cons = ConfigurationManager.ConnectionStrings["CTXDb"].ConnectionString;
        sqlConn = new SqlConnection(cons);
   }
}

```

HomController.cs:

```
public class HomeController : ApiController
{
  //Connection db = new Connection();  /// cannot create instance of an abstract class
   public HomeController:Connection()
   {
    //Here How can i get my connection 
   }
}

```
