Here is a post from MSDN explaining how to do it using SMO:

using System.Data.SqlClient;
using System.IO;
using Microsoft.SqlServer.Management.Common;
using Microsoft.SqlServer.Management.Smo;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            string sqlConnectionString = "Data Source=(local);Initial Catalog=AdventureWorks;Integrated Security=True";
            FileInfo file = new FileInfo("C:\\myscript.sql");
            string script = file.OpenText().ReadToEnd();
            SqlConnection conn = new SqlConnection(sqlConnectionString);
            Server server = new Server(new ServerConnection(conn));
            server.ConnectionContext.ExecuteNonQuery(script);
        }
    }
}

When I need to run sql scripts containing GO statements I usually read the entire file into a string and split it into a string array using GO as the delimiter.

I then connect to the database and run each statement in order.

It's quite easy and works well. Just make sure to keep your database connection open while running all statements. Also you may consider running them all in a transaction.
