Match(String, Int32, Int32) 方法會搜尋正規表示式模式 beginning 和length 參數所定義的 input 部分。 beginning 一律會定義要包含在搜尋中最左邊字元的索引,length 定義要搜尋的字元數上限。 它們會一起定義搜尋的範圍。 行為與 input 實際上是 input.Substring(beginning, length)一樣,不同之處在於,任何相符...

Use regex_search to match a substring within a target sequence and regex_iterator to find multiple matches. The functions that take a match_results object set its members to reflect whether the match succeeded and if so what the various capture groups in the regular expression captured. The ...
