问题描述

我有20个左右的字,我需要更换与文本块各种各样的字符。有没有办法做到这一点在一个单一的正则表达式,以及如何将这种正则表达式是什么?还是有更简单的方式来做到这一点。NET?

I have 20 or so characters that I need to replace with various other characters in a block of text. Is there a way to do this in a single regex, and what would this regex be? Or is there an easier way to do this in .NET?

例如,从我的映射表中摘录

For example, an excerpt from my mapping table is

OE => OE
Z =>ž
Y =>ÿ
A =>一个
A =>一个
A =>一个
A =>一个
△=>自动曝光

œ => oe
ž => z
Ÿ => Y
À => A
Á => A
 => A
à => A
Ä => AE

推荐答案

如果你真的很喜欢做单正则表达式,有办法做到这一点。

If you really like to do it in single regex, there is way to do that.

Dictionary<string, string> map = new Dictionary<string, string>() {
    {"œ","oe"},
    {"ž", "z"},
    {"Ÿ","Y"},
    {"À","A"},
    {"Á","A"},
    {"Â","A"},
    {"Ã","A"},
    {"Ä","AE"},
};

string str = "AAAœžŸÀÂÃÄZZZ";

Regex r = new Regex(@"[œžŸÀÂÃÄ]");

string output = r.Replace(str, (Match m) => map[m.Value]);

Console.WriteLine(output);

结果

AAAoezYAAAAEZZZ
