This should work:

C#

using System.Runtime.InteropServices;

[StructLayout(LayoutKind.Sequential)]
public struct ServerState
{
    public ushort Zone;
    [MarshalAs(UnmanagedType.ByValArray, SizeConst = 1)]
    public uint[] Init;
    [MarshalAs(UnmanagedType.ByValArray, SizeConst = 1)]
    public uint[] Link;
    [MarshalAs(UnmanagedType.ByValArray, SizeConst = 30)]
    public uint[] Spares;
    public ushort Sectors;
}
