Q: object serialization

Hello:

Here is one approach to doing what you want. Instead of a hashtable (which would also work) this uses a serializable class. I tend to put objects into a hashtable and deserialize the objects when pulling them back out of the hash using a similar approach but this example is pretty easy to follow and it seems like you could use it from the description you have provided.

Anyway, I hope it helps,

using System;

using System.IO;

using System.Runtime.Serialization.Formatters.Binary;

namespace SerializableThis

{

[Serializable]

class Person

{

public string FirstName;

public string LastName;

public int Age;

public string Street;

public string City;

public string State;

}

class Class1

{

[STAThread]

static void Main(string[] args)

{

Person pers = new Person();

pers.FirstName = "Cal";

pers.LastName = "Worthington";

pers.Age = 96;

pers.Street = "100 North Main";

pers.City = "Los Angeles";

pers.State = "CA";

Stream WriteStream = File.Create("C:\\Temp\\people.bin");

BinaryFormatter bf = new BinaryFormatter();

bf.Serialize(WriteStream, pers);

WriteStream.Close();

Person pers2 = new Person();

Console.WriteLine("Before Serialization:\n");

Console.WriteLine("First Name: " + pers2.FirstName);

Console.WriteLine("Last Name: " + pers2.LastName);

Console.WriteLine("Age: " + pers2.Age);

Console.WriteLine("Street: " + pers2.Street);

Console.WriteLine("City: " + pers2.City);

Console.WriteLine("State: " + pers2.State);

Stream ReadStream = File.OpenRead("C:\\Temp\\people.bin");

BinaryFormatter BinaryRead = new BinaryFormatter();

pers2 = (Person)BinaryRead.Deserialize(ReadStream);

ReadStream.Close();

Console.WriteLine("\n\nAfter Deserialization:\n");

Console.WriteLine("First Name: " + pers2.FirstName);

Console.WriteLine("Last Name: " + pers2.LastName);

Console.WriteLine("Age: " + pers2.Age);

Console.WriteLine("Street: " + pers2.Street);

Console.WriteLine("City: " + pers2.City);

Console.WriteLine("State: " + pers2.State);

Console.ReadLine();

}
