C＃中的正则表达式的Guid [英] C# Regex for Guid

问题描述

我需要通过一个字符串来解析和周围的每个GUID值加单引号。我想我可以使用正则表达式来做到这一点，但我不完全是一个正则表达式大师。

是否有一个良好的正则表达式用来标识一个GUID？

我的第二个问题是，一旦我找到了一个有效的正则表达式我假设我会使用 Regex.Replace（字符串，字符串，MatchEvaluator），但我不十分肯定的语法。也许是这样的：

 返回Regex.Replace（stringToFindMatch，GuidRegex，比赛= GT;
{
    返回的String.Format（'{0}'，match.Groups [0]的ToString（））;
}）;
 

这是我试图解析字符串可能看起来像这样：

  

SELECT
                                          passwordco0_.PASSWORD_CONFIG_ID为PASSWORD1_46_0_，
                                      从
                                          PASSWORD_CONFIG passwordco0_
                                      哪里
                                          passwordco0_.PASSWORD_CONFIG_ID = baf04077-a3c0-454b-ac6f-9fec00b8e170;
                                      @ P0 = baf04077-a3c0-454b-ac6f-9fec00b8e170 [类型：GUID（0）]

解决方案

这一个是很简单，就像你说的，不需要委托。

  resultString = Regex.Replace（subjectString，
     ？@^ [{（] [0-9A-F] {8} [ - ]（[0-9A-F] {4}？[ - ]？）{3} [0-9A-F] {12 } [）}] $，
     '$ 0'，
     RegexOptions.IgnoreCase）;
 

这符合以下样式，这是一个GUID。

都是等价的和可接受的格式

 ca761232ed4211cebacd00aa0057b223
CA761232-ED42-11CE-BACD-00AA0057B223
{CA761232-ED42-11CE-BACD-00AA0057B223}
（CA761232-ED42-11CE-BACD-00AA0057B223）
 

I need to parse through a string and add single quotes around each Guid value. I was thinking I could use a Regex to do this but I'm not exactly a Regex guru.

Is there a good Regex to use to identify a Guid?

My second question is once I've found a valid regex I'm assuming I would use Regex.Replace(String, String, MatchEvaluator) but I'm not quite sure of the syntax. Maybe something like:

return Regex.Replace(stringToFindMatch, GuidRegex, match =>
{
    return string.Format("'{0}'", match.Groups[0].ToString());
});

A string that I'm trying to parse may look like this:

"SELECT passwordco0_.PASSWORD_CONFIG_ID as PASSWORD1_46_0_, FROM PASSWORD_CONFIG passwordco0_ WHERE passwordco0_.PASSWORD_CONFIG_ID=baf04077-a3c0-454b-ac6f-9fec00b8e170; @p0 = baf04077-a3c0-454b-ac6f-9fec00b8e170 [Type: Guid (0)]"

解决方案

This one is quite simple and does not require a delegate as you say.

resultString = Regex.Replace(subjectString, 
     @"^[{(]?[0-9A-F]{8}[-]?([0-9A-F]{4}[-]?){3}[0-9A-F]{12}[)}]?$", 
     "'$0'", 
     RegexOptions.IgnoreCase);

This matches the following styles, which are all equivalent and acceptable formats for a GUID.

"ca761232ed4211cebacd00aa0057b223" 
"CA761232-ED42-11CE-BACD-00AA0057B223" 
"{CA761232-ED42-11CE-BACD-00AA0057B223}" 
"(CA761232-ED42-11CE-BACD-00AA0057B223)"
