Casting a byte array to a managed structure

Answer 1

//I have found this at: http://code.cheesydesign.com/?p=572 (I have not tested yet, but // at first sight it will work well.)

    /// 

    /// Reads in a block from a file and converts it to the struct
    /// type specified by the template parameter
    /// 
    /// 
    /// 
    /// 
    private static T FromBinaryReader(BinaryReader reader)
    {

        // Read in a byte array
        byte[] bytes = reader.ReadBytes(Marshal.SizeOf(typeof(T)));

        // Pin the managed memory while, copy it out the data, then unpin it
        GCHandle handle = GCHandle.Alloc(bytes, GCHandleType.Pinned);
        T theStructure = (T)Marshal.PtrToStructure(handle.AddrOfPinnedObject(), typeof(T));
        handle.Free();

        return theStructure;
    }
