startIndex = regexp(str,expression) 返回与正则表达式指定的字符模式匹配的每个str子字符串的起始索引。如果没有匹配,startIndex就是一个空数组。 [startIndex,endIndex] = regexp(str,expression) 返回起始索引和结束索引。 out = regexp(str,expression,outkey) 返回由outkey指定的输出。例如,如果outkey是'mat...
Note that the returned array also includes an empty string at the beginning and end of the array. The RegexMatchTimeoutException exception is thrown if the execution time of the split operation exceeds the time-out interval specified by the Regex.Regex(String, RegexOptions, TimeSpan) constructor...
The following example splits the string "characters" into as many elements as the input string contains, starting with the character "a". Because the null string matches the end of the input string, a null string is inserted at the end of the returned array. C# Copy Run using System; ...
$ means: a lowercase a, followed by a lowercase t, followed by a . character and the matcher must be at the end of the string."(at\.)" => The fat cat. sat. on the mat.Test the regular expression"(at\.)$" => The fat cat. sat. on the mat....
If you specify RightToLeft for the options parameter, the search for matches begins at the end of the input string and moves left; otherwise, the search begins at the start of the input string and moves right. The matchTimeout parameter specifies how long a pattern matching method should try...
startat is less than zero or greater than the length of input. Examples The following example uses the Match(String) method to find the first word in a sentence that ends in "es", and then calls the Matches(String, Int32) method to identify any additional words that end in "es". C#...
\< Start of a word \> End of a word \b Start or end of a word \w matches any letter, digit and underscore character \s matches a whitespace character — that is, a space or tab From what mentioned above, we can write regular expressions like this: \w{5} matches any five-letter...

Now let’s break the code into pieces to understand how it works. Basically, we are getting all ETR properties that end with “Words” and “Patterns.” All ETR predicates that count toward the regex limit should end with “Patterns” and “Words,” so this is the easiest...
