C# example: show contents of a DataTable using a command line tool

I think it's great to show important information in .NET DataTables (and DataSets). DataTables are like database tables, but only existing in memory. It's also possible to show the contents of a DataTable in a dosbox (aka "Windows command line" or "console"). This is a simple example I made with the free Visual Studio C# 2008 Express:

using System;
using System.Collections.Generic;
using System.Text;
using System.Data;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            System.IO.StringWriter sw;
            string output;
            DataTable dt = new DataTable();
            DataColumn dtcol = new DataColumn();
            dtcol.ColumnName = "name";
            dtcol.DataType = Type.GetType("System.Int32");
            dt.Columns.Add(dtcol);
            DataColumn dtcol2 = new DataColumn();
            dtcol2.ColumnName = "random";
            dtcol2.DataType = Type.GetType("System.Int32");
            dt.Columns.Add(dtcol2);
            DataColumn dtcol3 = new DataColumn();
            dtcol3.ColumnName = "id";
            dtcol3.DataType = Type.GetType("System.Int32");
            dtcol3.AutoIncrement = true;
            dt.Columns.Add(dtcol3);

            for (int i = 100; i <= 200; i++)
            {
                dt.Rows.Add(i,i+1000);
            }
            foreach (DataRow row in dt.Rows)
            {
                sw = new System.IO.StringWriter();
                foreach (DataColumn col in dt.Columns)
                sw.Write(row[col].ToString()+"\t");
                output = sw.ToString();
                Console.WriteLine(output);
            }
            Console.ReadKey();
        }
    }

}
