Convert byte[] to short[]

Okay, I'm trying to convert a byte[] to a short[], or Int16[].

List<Int16[]> lol = new List<Int16[]>();
byte[] b = System.Text.Encoding.Default.GetBytes("lolololololololololololoolol");
lol.Add(Convert.ToInt16(b));

MessageBox.Show(Encoding.Default.GetString(Encoding.Default.GetBytes(lol[0])));

That is something that I tried, but obviously, it doesn't work. So how would I do this?

It looks to me like you want to convert an entire array in one line. It could be done like this:

List<Int16[]> lol = new List<Int16[]>();
byte[] b = System.Text.Encoding.Default.GetBytes("lolololololololololololoolol");
lol.Add(Array.ConvertAll(b, x => Convert.ToInt16(x)));

        byte[] by = new byte[5];
        short[] sh = new short[5];
        by[0] = 0x1;
        by[1] = 0x2;
        by[2] = 0x3;
        by[3] = 0x4;
        by[4] = 0x5;

        for (int x = 0; x < sh.GetLength(0); x++)
        {
            sh[x] = by[x];
            MessageBox.Show(by[x].ToString());

That worked for me. Not sure if I am misunderstanding or not.

You probably want BitConverter.ToInt16(), which you'd need to call for each pair of bytes.

Or, use Buffer.BlockCopy to do it all at once (using the machine's native byte order).

You have to go through the byte array, and convert each element.

List<Int16[]> lol=new List<Int16[]>();
byte [] b=System.Text.Encoding.Default.GetBytes("lolololololololololololoolol");
Int16 [] a=new Int16 [b.Length];
for (Int32 i=0;i<a.Length;++i) {

    a[i]=Convert.ToInt16(b[i]);

}
lol.Add(a);
