我可以在C#中定义类似Perl的绑定运算符(=〜)吗? [英] Can I define a Perl-like binding operator (=~) in C#?

问题描述

我真的很喜欢能够在Perl中使用=〜和！〜根据正则表达式评估字符串.我想将此功能移植到C#，但看来，尽管您可以重载运算符，但不能创建新的运算符.

I really like being able to use =~ and !~ in Perl to evaluate a string against a regular expression. I'd like to port this functionality over to C#, but it appears that, while you can overload operators, you can't create new ones.

我正在考虑扩展字符串类型以提供Match()方法，该方法将允许我传递正则表达式以进行评估，但是我想知道还有更好的方法.

I'm considering extending the string type to provide a Match() method that will allow me to pass a regular expression in to be evaluated, but I'm wondering of there's a better way.

有人有更好的解决方案吗?

Anyone have a better solution?

推荐答案

尝试为字符串类创建一个扩展方法，该扩展类充当Regex.Match的快捷方式". 像这样:

Try creating an extension method to the string class that acts a "shortcut" to Regex.Match. Something like this:

public static class RegexExtensions
{
    public static bool Match(this string text, Regex re)
    {
        return Regex.Match(text, re);
    }
}
