It uses the regular expression \w*(ie|ei)\w* to match words that include the characters "ie" or "ei". It passes the first half of the matching words to the ReverseLetter method, which, in turn, uses the Replace(String, String, String, RegexOptions) method to reverse "i" and "e"...
In this example, our REGEX criteria dictate that the total character length must be 9. The first 3 characters should consist of uppercase letters, the subsequent 3 should be numeric values, and the final 3 should be lowercase letters. To accomplish this, we will employ a combination of sever...
\w*Match zero, one, or more word characters. \bEnd the match at a word boundary. Remarks TheMatch(String, String, RegexOptions)method returns the first substring that matches a regular expression pattern in an input string. For information about the language elements used to build a regular ...
g Global Search: Match all instances, not just the first. m Multiline: Anchor meta characters work on each line. 5.1 Case Insensitive The i modifier is used to perform case-insensitive matching. For example, the regular expression /The/gi means: an uppercase T, followed by a lowercase h...

\w+Match one or more word characters. esMatch the literal string "es". \bEnd the match at a word boundary. Remarks TheMatches(String, String)method is similar to theMatch(String, String)method, except that it returns information about all the matches found in the input string, instead of...

It is often the case when we want to build a regular expression out of a string without treating special characters from the string as special regular expression tokens. For example, if we want to replace all occurrences of the the stringlet text = "Hello."which we got from the user, we...
We can see that we evaluate each character individually, rather than being able to evaluate multiple characters together. We only look at the first character, and if it’s a match, we exit out to allow the engine to execute in full for Go. In .NET 5 Preview 2, we instead now generate...
