帮助纠正正则表达式 [英] Help correcting regular expression

问题描述

我有以下正则表达式，我想获取LocationMappingNew和MobileClassLibraries.BL.Mobile在评论中所处的值。我写的模式是返回一个空值的组。

//" __ type"："LocationMappingNew：＃ MobileClassLibraries.BL.Mobile"

string pattern = " \" __ type \"：\"（[A-Za-z] *）：＃ （[A-Za-z] *）\"， ;

匹配 match = 正则表达式 .Match（objString， pattern， RegexOptions .IgnoreCase）;

解决方案

您的模式有2个问题：
1。第二个[A-Za-z]不允许有时间段。您可以将其更改为：[A-Za-z。]
2。看起来您的模式末尾有逗号，因此您的输入将不匹配。

请尝试："\" __ type \"：\"（[A -Za-Z] *）：＃（[A-ZA-Z] *）\""结果

。

I have the following regular expression where I want to get the value where LocationMappingNew and MobileClassLibraries.BL.Mobile sit in the comment.  The pattern I wrote is returning 1 group with an empty value.

//"__type":"LocationMappingNew:#MobileClassLibraries.BL.Mobile"

string pattern = "\"__type\":\"([A-Za-z]*):#([A-Za-z]*)\",";

Match match = Regex.Match(objString,pattern,RegexOptions.IgnoreCase);

解决方案

2 problems with your pattern:
1. The 2nd [A-Za-z] doesn't allow for periods. You can change it to: [A-Za-z.]
2. It looks like you have a trailing comma at the end of your pattern, therefore your input won't match.

Try: "\"__type\":\"([A-Za-z]*):#([A-Za-z.]*)\""
