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

(我听说LINQ是新的黑色，所以这是我尝试使用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());
}

(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.)

(（注意：使用Random类会使其不适用于任何与安全性相关的内容 ，例如创建密码或令牌。如果需要强大的随机数生成器，请使用RNGCryptoServiceProvider类。）)
