将Wordpress-splicate文件名函数从PHP转换为C#

Question

我正在尝试将Wordpress sanitize_file_name函数从PHP转换为C#，这样我就可以在自己构建的web应用程序上使用它为我的网站文章生成unicode slugs。

这是我的班级：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text.RegularExpressions;
using System.Web;
 namespace MyProject.Helpers
{
 public static class Slug
 {
    public static string SanitizeFileName(string filename)
    {
        string[] specialChars = { "?", "[", "]", "/", "\", "=", "< ", "> ", ":", ";", ",", "'", """, "& ", "$", "#", "*", "(", ")", "|", "~", "`", "!", "{", "}" };
        filename = MyStrReplace(filename, specialChars, "");
        filename = Regex.Replace(filename, @"/[s-]+/", "-");
        filename.TrimEnd('-').TrimStart('-');
        filename.TrimEnd('.').TrimStart('.');
        filename.TrimEnd('_').TrimStart('_');

        return filename;
    }
    private static string MyStrReplace(string strToCheck, string[] strToReplace, string newValue)
    {
        foreach (string s in strToReplace)
        {
            strToCheck = strToCheck.Replace(s, newValue);
        }
        return strToCheck;
    }
   // source: http://stackoverflow.com/questions/166855/c-sharp-preg-replace
    public static string PregReplace(string input, string[] pattern, string[] replacements)
    {
        if (replacements.Length != pattern.Length)
            throw new ArgumentException("Replacement and Pattern Arrays must be balanced");
        for (int i = 0; i < pattern.Length; i++)
        {
            input = Regex.Replace(input, pattern[i], replacements[i]);
        }
        return input;
    }
 }
}

我放了一个标题，比如："let's say that I have --- in there what to do"，但我得到了相同的结果，只是修剪了一个撇号（让我们->lets），其他什么都没有改变。

我想要与Wordpress相同的等效转换。使用ASP.NET 4.5/C#

Answer 1

由于在C#中没有操作修饰符，因此没有正则表达式分隔符。

解决方案是简单地从模式中删除/符号：

filename = Regex.Replace(filename, @"[s-]+", "-");
                                    ^      ^
