1、生成字母和数字结合的随机序列：
Random
rn = new
Random();
string
charsToUse = "AzByCxDwEvFuGtHsIrJqKpLoMnNmOlPkQjRiShTgUfVeWdXcYbZa1234567890";
MatchEvaluator
RandomChar = delegate
(Match m)
{
return
charsToUse[rn.Next( charsToUse.Length )].ToString();
};
Console.WriteLine(
Regex.Replace( "XXXX-XXXX-XXXX-XXXX-XXXX",
"X",
RandomChar ) );
//
Lv2U-jHsa-TUep-NqKa-jlBx
Console.WriteLine(
Regex.Replace( "XXXX",
"X",
RandomChar ) );
//
8cPD

2、生成字节随机序列
byte[] randBytes = new byte[108];
Random randNum = new Random();
randNum.NextBytes(randBytes);
