serialize dictionary

Here's a simple example using binary serialization:

using System;

using System.Collections.Generic;

using System.Runtime.Serialization;

using System.Runtime.Serialization.Formatters.Binary;

using System.IO;

class Test

{

static void Main()

{

var dict = new Dictionary();

dict.Add("1", "abcdefgh");

dict.Add("2", "vulpes");

IFormatter formatter = new BinaryFormatter();

// serialize to disk

using (FileStream s = File.Create("dictionary.bin"))

{

formatter.Serialize(s, dict);

}

// deserialize to a new dictionary

Dictionary dict2;

using(FileStream s = File.OpenRead("dictionary.bin"))

{

dict2 = (Dictionary)formatter.Deserialize(s);

}

// check it worked

foreach(string key in dict2.Keys)

{

Console.WriteLine("Key = {0}, Value = {1}", key, dict2[key]);

}

Console.ReadKey();

}
