*DataSet序列化，这段代码研究

DataSet序列化，这段代码研究研究、学习学习。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Data;
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;

namespace PromTest
{

    class Program
    {
        static void Main(string[] args)
        {
            DataSet ds = new DataSet();
            DataTable table = new DataTable("tab1");
            ds.Tables.Add(table);
            table.Columns.Add(new DataColumnEx() { ItemCategory = "测试" });

            BinSerialize(ds);
            object obj = BinDeserialize();

            if (((DataSet)obj).Tables[].Columns[] is DataColumnEx)
            {
                Console.WriteLine((((DataSet)obj).Tables[].Columns[] as DataColumnEx).ItemCategory);
            }

            Console.Read();
        }

        static void BinSerialize(object info)
        {

            using (Stream stream = new FileStream("c:\\a.bin", FileMode.Create, FileAccess.Write))
            {
                BinaryFormatter bf = new BinaryFormatter();

                bf.Serialize(stream, info);
            }
        }

        static object BinDeserialize()
        {
            using (Stream stream = new FileStream("a.bin", FileMode.Open, FileAccess.Read))
            {
                BinaryFormatter bf = new BinaryFormatter();

                return bf.Deserialize(stream);
            }
        }
    }

    public class DataColumnEx : DataColumn
    {
        public string ItemCategory
        { get; set; }
    }
}
