Hi, And thanks for any help.
I am having trouble declaring a struct containing strings that can be
Serialized using the following functions. It works, but the strings wont
store the right number of characters, they store one less with a null at the
end! Whats the point in a marshalling as fixed length if it wastes space
with a null! How can i make it marshall the strings as "proper" fixed length
strings, where the full 8 (or 3) characters can be stored without having to
extend the length of the strings.
/* Generic serialization functions */

public class RawSerializer
{
public static byte[] RawSerialize( object anything )
{
int rawsize = Marshal.SizeOf( anything );
IntPtr buffer = Marshal.AllocHGlobal( rawsize );
Marshal.StructureToPtr( anything, buffer, false );
byte[] rawdatas = new byte[ rawsize ];
Marshal.Copy( buffer, rawdatas, 0, rawsize );
Marshal.FreeHGlobal( buffer );
return rawdatas;
}
public static object RawDeserialize( byte[] rawdatas, Type anytype )
{
int rawsize = Marshal.SizeOf( anytype );
if( rawsize > rawdatas.Length )
return null;
IntPtr buffer = Marshal.AllocHGlobal( rawsize );
Marshal.Copy( rawdatas, 0, buffer, rawsize );
object retobj = Marshal.PtrToStructure( buffer, anytype );
Marshal.FreeHGlobal( buffer );
return retobj;
}
}
[StructLayout(LayoutKind.Sequential, CharSet=CharSet.Ansi)]
public struct FileInfoRecord
{
public uint fileId;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 8)]
public string fileName;
[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 7)]
public string fileType;
public uint fileDirectory;
public DateTime fileModified;
public DateTime fileCreated;
public uint fileSize;
}
Thanks
