It sounds like you're declaring this variable within a method but you should be declaring this variable at page level.

You should have something like:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

using System.Data;

namespace WebApplication2
{
  public partial class _Default : System.Web.UI.Page
  {
    private string _strpolladdress; //will contain the string
    protected void Page_Load(object sender, EventArgs e)
    {
      //initialize _strpolladdress with data from the database...
    } 
    
    private void methodA(){
      //do stuff with _strpolladdress
    }     
    private void methodB(){
      //do stuff with _strpolladdress
    } 
  }
}
