Get list of all sql servers installed in the system

I am trying to get list of all SQL Servers installed in the machine 开发者_StackOverflow中文版and populate them in a drop downlist. I have searched in google and tried the following:

using System;
using System.Data;
using Microsoft.SqlServer.Management.Smo;

namespace SMOTest
{
    class Program
    {
        static void Main()
        {
           DataTable dt = SmoApplication.EnumAvailableSqlServers(false);
           if (dt.Rows.Count > 0)
           {
              foreach (DataRow dr in dt.Rows)
              {
                 Console.WriteLine(dr["Name"]);
              }
           }
        }
    }
}

However I didn't find a reference for Microsoft.SqlServer.Management.Smo;

What is the best way to get all the sqlserver names and populate it in a drop down list?

If you dont find it than you can google it and than you can pass the reference of it the simplest way to achive it.
