Question

我正在尝试做两件事，首先，为字符串提供伪本地化（leet speak）转换，其次，根据百分比比例随机化替换字符串中包含的字符，IE：every 5％-30％的时间......

另外，除此之外，我需要在字符串的开头，中间或结尾（随机）中添加固定数字或特殊字符。

每个人都知道，这是一个随机密码生成器。

我的问题是，如何将所述功能合并到我目前正在使用的代码库中？更好的是，我怎样才能有效地做到这一点？

感谢您提供的任何帮助。

namespace pseudoLocalizer
{
class RegexTuple
{
    Regex thisRegex;
    string replaceWith;

    public RegexTuple(string expression, string replacement)
    {
        thisRegex = new Regex(expression);
        replaceWith = replacement;

    }

    public string GetReplaceWith()
    {
        return replaceWith;
    }

    public Regex GetRegex()
    {
        return thisRegex;
    }
}

class pLocalizeEngine
{
    //leet table.
    RegexTuple[] arrRegexTuples = {

    public pLocalizeEngine()
    {
        //
    }

    public string Localize(string oldString)
    {
        string pLocalString = oldString;
        foreach (RegexTuple tuple in arrRegexTuples)
        {
            pLocalString = tuple.GetRegex().Replace(pLocalString, tuple.GetReplaceWith());
        }
        return pLocalString;
    }
}

假设您需要密码生成器，我建议您：

private const string ValidCharacters = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz1234567890@<()!?~+";
private Random random = new Random();

private string RandomPasswordGenerator(int length)
{
    string password = string.Empty;
    while (length > 0)
    {
        password += ValidCharacters[random.Next(0, ValidCharacters.Length - 1)];
        length--;
    }
    return password;
}
