d比[0-9]效率低
本文关键字：效率 | 更新日期: 2023-09-27 18:14:23
我昨天对一个答案发表了评论，其中有人在正则表达式中使用[0123456789]而不是[0-9]或'd。我说过，使用范围或数字说明符可能比使用字符集更有效。
我决定今天测试一下，发现令我惊讶的是(至少在c# regex引擎中)'d似乎比其他两个似乎差别不大的效率低。下面是我的测试输出，超过10000个随机字符串，1000个随机字符，其中5077实际上包含一个数字:
Regex 'd took 00:00:00.2141226 result: 5077/10000
Regex [0-9] took 00:00:00.1357972 result: 5077/10000 63.42 % of first
Regex [0123456789] took 00:00:00.1388997 result: 5077/10000 64.87 % of first
这让我很惊讶，有两个原因，如果有人能给我一些启示，我会很感兴趣:
- 我本以为范围的执行会比集合更有效。 我不明白为什么
'd比[0-9]差。'd不仅仅是[0-9]的简写?using System;

'd检查所有Unicode数字，而[0-9]仅限于这10个字符。例如，波斯语数字۱۲۳۴۵۶۷۸۹是Unicode数字的一个例子，它与'd匹配，但与[0-9]不匹配。
您可以使用以下代码生成所有这些字符的列表:
var sb = new StringBuilder();
for(UInt16 i = 0; i < UInt16.MaxValue; i++)
{
string str = Convert.ToChar(i).ToString();
if (Regex.IsMatch(str, @"'d"))
sb.Append(str);
}
Console.WriteLine(sb.ToString());

感谢ByteBlast在文档中注意到这一点。只需更改regex构造函数:
var rex = new Regex(regex, RegexOptions.ECMAScript);
给出新的计时:
Regex 'd took 00:00:00.1355787 result: 5077/10000
Regex [0-9] took 00:00:00.1360403 result: 5077/10000 100.34 % of first
Regex [0123456789] took 00:00:00.1362112 result: 5077/10000 100.47 % of first
From regex中的" 'd "表示数字吗?:
[0-9]不等于'd。[0-9]只匹配0123456789字符，而'd匹配[0-9]和其他数字字符，例如阿拉伯东部数字٠١٢٣٤٥٦٧٨٩
除了来自Sina Iravianian的回答之外，这里是他的代码的。net 4.5版本(因为只有那个版本支持UTF16输出，c.f.前三行)。使用全范围的Unicode码位。由于缺乏对更高的Unicode平面的适当支持，许多人没有意识到总是检查和包括更高的Unicode平面。然而，它们有时确实包含一些重要的字符。
由于'd不支持regex中的非bmp字符(感谢xanatos)，这里使用Unicode字符数据库的版本
