C# 中的 Slugify 和字符转写 [英] Slugify and Character Transliteration in C#

问题描述

我正在尝试将以下 slugify 方法从 PHP 转换为 C#:http://snipplr.com/view/22741/slugify-a-string-in-php/

I'm trying to translate the following slugify method from PHP to C#: http://snipplr.com/view/22741/slugify-a-string-in-php/

为方便起见，这里是上面的代码:

For the sake of convenience, here the code from above:

/**
 * Modifies a string to remove al non ASCII characters and spaces.
 */
static public function slugify($text)
{
    // replace non letter or digits by -
    $text = preg_replace('~[^\pLd]+~u', '-', $text);

    // trim
    $text = trim($text, '-');

    // transliterate
    if (function_exists('iconv'))
    {
        $text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);
    }

    // lowercase
    $text = strtolower($text);

    // remove unwanted characters
    $text = preg_replace('~[^-w]+~', '', $text);

    if (empty($text))
    {
        return 'n-a';
    }

    return $text;
}

除了找不到与以下 PHP 代码行等效的 C# 代码之外，其余部分的代码我没有遇到任何问题:

I got no probleming coding the rest except I can not find the C# equivalent of the following line of PHP code:

$text = iconv('utf-8', 'us-ascii//TRANSLIT', $text);

这样做的目的是将非 ASCII 字符，例如 Reformáció Genfi Emlékműve Előtt 翻译成 reformacio-genfi-emlekmuve-elott

推荐答案

我还想补充一点，//TRANSLIT 删除了撇号，而 @jxac 解决方案没有解决这个问题.我不知道为什么，但首先将其编码为西里尔字母，然后再编码为 ASCII，您会得到与 //TRANSLIT 类似的行为.

I would also like to add that the //TRANSLIT removes the apostrophes and that @jxac solution doesn't address that. I'm not sure why but by first encoding it to Cyrillic and then to ASCII you get a similar behavior as //TRANSLIT.

var str = "éåäöíØ";
var noApostrophes = Encoding.ASCII.GetString(Encoding.GetEncoding("Cyrillic").GetBytes(str)); 

=> "eaaoiO"
