Each group has a number starting with 1, so you can refer to (backreference) them in your replace pattern. They can particularly be difficult to maintained as adding or removing a group in the middle of the regex upsets the previous numbering used via Matcher#group(int groupNumber) or used as back-references (back-references will be covered in the next tutorials). As an example, in the string “this is a test”, the search string “(this is)(? a )” matches the "this is a " successfully. こんにちは！エンジニアの中沢です。 C#には正規表現で文字列のパターンを指定して置換するための「Replaceメソッド」あります。 正規表現でパターンを指定すれば任意の文字列を書き換えることができるので、上手く活用してください。 The third named group is year.
