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
