若lookingAt()方法返回true,matcher调用group()可以返回lookingAt()方法找到的匹配模式的子序列。 函数:public boolean find(int start); 作用:matcher调用该方法判断input从参数start指定的位置开始是否有和regex匹配的子序列,参数start取值为0时,该方法和lookingAt

startat 参数定义第一个分隔符开始搜索的点(这可用于跳过前导空格)。 有关startat的更多详细信息,请参阅 Match(String, Int32)的“备注”部分。 如果在字符串中 count+1 位置找不到匹配项,该方法将返回一个包含 input 字符串的一个元素数组。 如果找到一个或多个匹配项,则返回的数组的第一个元素包含字符串...
startat 參數會定義第一個分隔符開始搜尋的點(這可用於略過前置空格符)。 如需startat的詳細資訊,請參閱 Match(String, Int32)的一節。 如果字串中 count+1 位置找不到相符專案,此方法會傳回包含 input 字串的一個元素陣列。 如果找到一或多個相符專案,則傳回陣列的第一個元素會包含字元串的第一個部分,...
Match match = regex.Match(input, startAt);while(match.Success) {// Handle match here...match = match.NextMatch(); } The regular expression pattern for which theMatches(String, Int32)method searches is defined by the call to one of theRegexclass constructors. For more information about the...

match. This behavior guarantees that the regular expression engine will progress through the string. Otherwise, because an empty match does not result in any forward movement, the next match would start in exactly the same place as the previous match, and it would match the same empty...
Start(String) Returns the start index of the subsequence captured by the given named-capturing group during the previous match operation. ToArray<T>()(Inherited fromObject) ToMatchResult() Returns the match state of this matcher as aMatchResult. ...
