is there anyway to convert object (or class) to byte[] ?
like System.IO.DriveInfo to byte[] ?
if so . how can I unconvert that ?

static void Main(string[] args) { using (var stream = new MemoryStream()) { // serialize object var formatter = new BinaryFormatter(); var foo = new Foo(); formatter.Serialize(stream, foo); // get a byte array // (thanks to Matt for more concise syntax) var bytes = stream.GetBuffer(); // deserialize object var foo2 = (Foo) formatter.Deserialize(stream); } } [Serializable] class Foo:ISerializable { public string data; #region ISerializable Members public void GetObjectData(SerializationInfo info, StreamingContext context) { info.AddValue("data",data); } #endregion }

You can just grab the array out of the MemoryStream with
GetBuffer()

how can I store bytes[] in stream for Deserialize ?

@pedram that's what the Serialize call does
If the class is Serializable you can use a BinaryFormatter to accomplish this. The followin code snippet can provide you with a start:

I think the term you are looking for is "serialization"

You could use a BinaryFormatter to serialize an object to a MemoryStream, then get the bytes from that. BinaryFormatter can do the transformation back to object from byte[] array too (deserialization). The data will look very strange though. It is not the same as the memory image if that's what you want.
