我听说LINQ是新的黑色，所以这里的使用LINQ我尝试：

I heard LINQ is the new black, so here's my attempt using LINQ:

private static Random random = new Random();
public static string RandomString(int length)
{
    const string chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
    return new string(Enumerable.Repeat(chars, length)
      .Select(s => s[random.Next(s.Length)]).ToArray());
}

^{（注：的使用Random类的使这个不适合任何与安全有关的，如创建密码或令牌结果
＆NBSP; ＆NBSP; ＆NBSP; ＆NBSP; ＆NBSP; ＆NBSP;使用RNGCryptoServiceProvider类，如果你需要一个强大的随机数生成器）}

^{(Note: The use of the Random class makes this unsuitable for anything security related, such as creating passwords or tokens.
           Use the RNGCryptoServiceProvider class if you need a strong random number generator.)}
