How to compress and decompress binary streams in Unity

recently I needed to compress a binary stream that was getting to big to be serialized over internet. I could not find any way to compress files easily, so eventually I used a 3rd party library that works very well in Unity3D (web player included): SharpZipLib

I suppose the following code could be handy for someone:

using ICSharpCode.SharpZipLib.BZip2;
using System.Runtime.Serialization.Formatters.Binary; 
using System.IO;

static void Compress (string nameOfTheFileToSave, ISerializable objectToSerialize)
{
	using (FileStream fs = new FileStream(nameOfTheFileToSave, FileMode.Create))
	{
		using (MemoryStream objectSerialization = new MemoryStream())
		{
			BinaryFormatter bformatter = new BinaryFormatter();
			bformatter.Serialize(objectSerialization, objectToSerialize);

			using (BinaryWriter binaryWriter = new BinaryWriter(fs))
			{
				binaryWriter.Write(objectSerialization.GetBuffer().Length);	//write the length first

				using (BZip2OutputStream osBZip2 = new BZip2OutputStream(fs))
				{
					osBZip2.Write(objectSerialization.GetBuffer(), 0, objectSerialization.GetBuffer().Length); //write the compressed file
				}
			}
		}
	}
}

static void Decompress(string nameOfTheFileToLoad)
{
	using (FileStream fs = new FileStream(nameOfTheFileToLoad, FileMode.Open))
	{
		using (BinaryReader binaryReader = new BinaryReader(fs))
		{
			int length = binaryReader.ReadInt32();	//read the length first
			byte[] bytesUncompressed = new byte[length]; //you can convert this back to the object using a MemoryStream ;)

			using (BZip2InputStream osBZip2 = new BZip2InputStream(fs))
			{
				osBZip2.Read(bytesUncompressed, 0, length); //read the decompressed file
			}
		}
	}
 }
