I have this byte[]: 00 28 00 60 00 30 10 70 00 22 FF FF.

I want to combine each pair of bytes into a word: 0028 0060 0030 1070 0022 FFFF.

I also want to turn the word array into a string: "0028 0060 0030 1070 0022 FFFF" (without using byte[]).

I fixed SLaks code and it works:

StringBuilder sb = new StringBuilder();
for(var i = 0; i < words.Length; i++)
{
   sb.AppendFormat("{0:X4} ", words[i]);
}

Like this:

StringBuilder words;

for(int i = 0; i < bytes.Length; i += 2) {
    if (i > 0) words.Append(' ');
    words.AppendFormat({0:X2}{1:X2}", bytes[i], bytes[i + 1]);
}

Edit: For ushorts:

StringBuilder words;

for(int i = 0; i < words.Length; i++) {
    if (i > 0) words.Append(' ');
    words.AppendFormat({0:X4}", ushortArray[i]);
}

That's going from byte[] to string, and is good to know, but wanted to know how to deal with word array (ushort[]). – OIO Sep 5 '10 at 4:44
