Is there a nice way to split an int into two shorts (.NET)?

Question

I think that this is not possible because Int32 has 1 bit sign and have 31 bit of numeric information and Int16 has 1 bit sign and 15 bit of numeric information

Unsafe code in C#, overflow doesn't occur, detects endianness automatically:

using System;
class Program
{
    static void Main(String[] args)
    {
        checked // Yes, it works without overflow!
        {
            Int32 original = Int32.MaxValue;
            Int16[] result = GetShorts(original);
            Console.WriteLine("Original int: {0:x}", original);
            Console.WriteLine("Senior Int16: {0:x}", result[1]);
            Console.WriteLine("Junior Int16: {0:x}", result[0]);
            Console.ReadKey();
        }
    }
    static unsafe Int16[] GetShorts(Int32 value)
    {
        byte[] buffer = new byte[4];
        fixed (byte* numRef = buffer)
        {
            *((Int32*)numRef) = value;
            if (BitConverter.IsLittleEndian)
                return new Int16[] { *((Int16*)numRef), *((Int16*)numRef + 1) };
            return new Int16[] { 
                (Int16)((numRef[0] << 8) | numRef[1]),  
                (Int16)((numRef[2] << 8) | numRef[3])
            };
        }
    }
}
