// I quite like:
var i = int.Parse(Console.ReadLine()) << 16;
i |= 65535 & int.Parse(Console.ReadLine());
Console.WriteLine((i >> 16));
Console.WriteLine((i << 16) >> 16);

//Or if you are afraid of bitwise operators:
var i = BitConverter.ToInt32(
     BitConverter.GetBytes(short.Parse(Console.ReadLine()))
    .Concat(
     BitConverter.GetBytes(short.Parse(Console.ReadLine()))).ToArray(),
     0);

Console.WriteLine(BitConverter.ToInt16(BitConverter.GetBytes(i), 0));
Console.WriteLine(BitConverter.ToInt16(BitConverter.GetBytes(i), 2));


//Or if you like variable length data:
//http://stackoverflow.com/questions/11979184/reading-bit-aligned-data/11979287#11979287

//The following is useful for large quantities of data:
var i = new int[1];
Buffer.BlockCopy(new[] { short.Parse(Console.ReadLine()), short.Parse(Console.ReadLine()) }, 0, i, 0, 4);
var s = new short[2];
Buffer.BlockCopy(i, 0, s, 0, 4);
Console.WriteLine(s[0]);
Console.WriteLine(s[1]);


//Oh, and here's a trick I bet they never taught you in school:
var mi = new MyInteger { a = short.Parse(Console.ReadLine()), b = short.Parse(Console.ReadLine()) };
var mi2 = new MyInteger { i = mi.i };
Console.WriteLine(mi2.a);
Console.WriteLine(mi2.b);

[StructLayout(LayoutKind.Explicit)]
struct MyInteger
{
    [FieldOffset(0)]
    public int i;
    [FieldOffset(0)]
    public short a;
    [FieldOffset(2)]
    public short b;
