Как соеденить базу даных на сервере с програмой на компютере?

Data Source=myServerAddress;Initial Catalog=myDataBase;User Id=myUsername;Password=myPassword;

using System;
using System.Data;
using System.Data.SqlClient;
namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
           SqlConnection con=new SqlConnection("Data Source=myServerAddress;Initial Catalog=myDataBase;User Id=myUsername;Password=myPassword");
           SqlCommand command = new SqlCommand();
           command.Connection = con;
           con.Open();
           command.CommandText = "SQL запрос";
           command.ExecuteNonQuery();
           con.Close();
        }
    }
}

SqlConnection con = new SqlConnection("Data Source=http://prog.netau.net ;Initial Catalog=/base/NORTHWND.MDF;User Id=myUsername;Password=myPassword");

NorthwindDataContext northWindDataContext = new NorthwindDataContext() ; 
var queryResults = from с in northWindDataContext.Customers 
where c.Country == "USA" 
select new { 
ID=c.CustomerID, 
Name=c.CompanyName, 
City=c.City, 
State=c.Region 
}; 
foreach (var item in queryResults) { 
Console.WriteLine(item);

DataClasses1DataContext proba = new DataClasses1DataContext();
