推荐答案

这可能对你有帮助....

This may help you....

void gen_random(char *s, const int len) {
    static const char alphanum[] =     "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";

    for (int i = 0; i < len; ++i) {
        s[i] = alphanum[rand() % (sizeof(alphanum) - 1)];
    }

    s[len] = 0;
}

我认为GUID和Regex可以让这更容易和可靠...



请尝试以下代码，每次创建一个20长度的随机不同字符串。

I think GUID and Regex could make this much easier and reliable...

Do try the following code which creates a random different string of 20 length each time.

Guid guid = Guid.NewGuid();

           string id = guid.ToString().Substring(0, 20);
           Regex R1 = new Regex(id);
           id = Regex.Replace(id, @"\s|\-|'", "");

           Response.Write(id);

希望这将有助于.... :)
