QuickStart! - .NET Regular Expressions Tutorial


Regular expressions provide a powerful, flexible, and efficient method for processing text. The extensive pattern-matching notation of regular expressions enables you to quickly parse large amounts of text to find specific character patterns; to validate text to ensure that it matches a predefined pattern (such as an e-mail address); to extract, edit, replace, or delete text substrings; and to add the extracted strings to a collection in order to generate a report. For many applications that deal with strings or that parse large blocks of text, regular expressions are an indispensable tool.

In this QuickStart! on Microsoft's .NET Regular Expressions implementation, Mark Long introduces you to the concept and basic usage of Regular Expressions in Microsoft's .NET development environment. Work files are included. To begin learning today, simply click on the movie links.
