Community server to blogml code

I wrote some custom code to convert the community server blog entries to a blogml version so that I could import it into blogengine.net. I considered using the blogml assembly to create the code, but decided to hand-code it instead.

The way to use this is to create a blog, write one post, export it out (settings->export), and then hand-insert the categories and post sections into that exported file, then re-import it back. I decided to skip comments to make things easier.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data.SqlClient;
using System.IO;

namespace blogconverter
{
    class Program
    {
        static SqlDataReader Execute(string query)
        {
            SqlCommand command = GetConnection().CreateCommand();
            command.CommandText = query;
            SqlDataReader reader = command.ExecuteReader();
            return reader;
        }

        static SqlConnection GetConnection()
        {
            SqlConnection connection =
                new SqlConnection(@"Data Source=HOMELAPTOP\SQLEXPRESS;Database=BCCommunityServer;Integrated Security=SSPI;");
            connection.Open();

            return connection;
        }

        static void Main(string[] args)
        {
            using (StreamWriter writer = File.CreateText(@"c:\data\website\posts.xml"))
            {
                string categories = GetCategories();

                string posts = GetPosts();

                writer.WriteLine(categories);
                writer.WriteLine(posts);
            }

        }

        static Dictionary _CategoryLookup = 
            new Dictionary();

        static string GetCategories()
        {
            StringBuilder b = new StringBuilder();
            b.Append("");
            SqlDataReader reader = Execute(QueryCategory);

            while (reader.Read())
            {
                int categoryId = (int) reader.GetValue(0);
                string name = (string) reader.GetValue(1);

                Guid id = Guid.NewGuid();

                _CategoryLookup.Add(categoryId, id);

                b.Append(String.Format(
                    @"
                       

So, what do you think ?
