Serialization in .NET Programming

If you want to Binary or XML Serialization in .NET Programming and you are using C#, you can use following code.

using System;
using System.IO;
using System.Collections;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters;
using System.Runtime.Serialization.Formatters.Binary;
using System.Web.Mail;

namespace npuInfoCS.Utilities
{
public class Serialization
{
public enum SerializationFormat {Xml, Binary}

public static System.Boolean SerializeToDisk(string path, object request, SerializationFormat format)
{
try
{
System.IO.MemoryStream oStream = Serialize(request, format);
if(System.IO.File.Exists(path)) System.IO.File.Delete(path);
System.IO.FileStream output = System.IO.File.Open(path, System.IO.FileMode.CreateNew);
output.Write(oStream.ToArray(),0,Convert.ToInt32(oStream.Length));
output.Close();
oStream.Close();
return true;
}
catch(Exception e)
{
return false;
}
}

public static object DeSerializeFromDisk(string path, SerializationFormat format)
{
try
{
if(System.IO.File.Exists(path))
{
System.IO.FileStream input = System.IO.File.Open(path, System.IO.FileMode.Open);
byte[] filecontents=new byte[Convert.ToInt32(input.Length)];
input.Read(filecontents, 0, Convert.ToInt32(input.Length));
input.Close();
//System.IO.File.Delete(path);
System.IO.MemoryStream inStream = new System.IO.MemoryStream(filecontents);
object newObj = DeSerialize(inStream, format);
inStream.Close();
return newObj;
}
else
{
return null;
}
}
catch(Exception e)
{
return null;
}
}
