警告

將正則運算式引擎的超時值設定為InfiniteMatchTimeout , 可能會導致依賴過量回溯的正則運算式似乎在處理幾乎符合正則運算式模式的文字時停止回應。Setting the regular expression engine's time-out value to InfiniteMatchTimeout can cause regular expressions that rely on excessive backtracking to appear to stop responding when processing text that nearly matches the regular expression pattern. 如果您停用超時時間, 您應該確定正則運算式不依賴過量的回溯, 而且它會處理幾乎符合正則運算式模式的文字。If you disable time-outs, you should ensure that your regular expression does not rely on excessive backtracking and that it handles text that nearly matches the regular expression pattern.
