unity3.0 in web player problem

Unity Engine
1

if it can’t use Marshal class (using System.Runtime.InteropServices) in the web player unity3.0?

but there is no problem in unity2.6

What is the reason?:frowning:

If that was possible in 2.6, it was definitely a mistake. The webplayer is supposed to be completely isolated from anything outside of the project package - memory and code wise.

if can’t using Marshal Class in web…
Are there any other way to convert byte array to struct?

Look up .NET binary serialisation. This seems a good place to start: Binary Serialization | Microsoft Learn

Binary Serialisation of C#:

using System.Runtime.Serialization.Formatters.Binary;

public static byte[ ] ObjectToBytes( object obj )
{
BinaryFormatter bf = new BinaryFormatter();
MemoryStream stream = new MemoryStream();

try
{
bf.Serialize(stream, obj);
}
catch (Exception ex)
{
Debug.Log(" * ObjectToBytes error: " + ex.Message);
return null;
}

byte[ ] byteContent = stream.ToArray();
return byteContent;
}

but there is another problem: the size of bytes ( result of ObjectToBytes ) is very big ,

is very different with Marshal.StructureToPtr
