The following example illustrates the use of the IsMatch(String, String) method to determine whether a string is a valid part number. The regular expression assumes that the part number has a specific format that consists of three sets of characters separated by hyphens. The first set, which ...
("id", 0), new StringDataFrameColumn("text", 0)); // Filter text containing specific substring using regex expression // DataFrameColumn texts = input.Columns["text"]; for(int i = 0; i < texts.Length; ++i) { if(Regex.IsMatch((string)texts[i], sqlParams["@regexExpr"...

REGEX is a powerful and flexible way to search for and match patterns in text strings. You can use REGEX to perform various tasks, such as: Extracting specific information from a text string, such as names, dates, numbers, etc. Replacing parts of a text string with another text string, s...
Regex()andRegex Match()match a pattern in a given string but return different results. To transforms your string into another string, useRegex(). To identify the substrings that match specific parts of the pattern, useRegex Match().
The String.Replace function has been a valuable tool for years, allowing programmers to change strings by replacing a specific substring with another substring. While this is usually enough, the Regex.Replace function goes a step (ok, maybe 10 steps) further. It allows replacement of text using...
I think a string pattern type is a natural extension that allows for non-finite value restrictions to be expressed. I'm writing type definitions for an existing codebase. Many arguments and properties accept strings of a specific format: ❌ Formatted representation of a date, eg "2021-04-...
Thetestmethod can only be called on valid regular expressions. The method checks if there is a match between the regular expression and the string and returns the result. Notice that the regular expression is not wrapped in a string.
"keywords": {"type":"array","items": {"type":"string","description":"A tag/keyword that this package relates to."} }, Other parts make use of the pattern restriction, so it isn't a case of "specific string restrictions are never encoded into the schema", more like "composer valida...
