Microsoft’s .NET provides a solid implementation of regular expressions. The original .NET Framework, .NET Core, and .NET 5.0 all implement the same regex flavor. You can use it in your C# application simply by importing the namespace System.Text.RegularExpressions. RegexBuddy makes it very easy to use the power of regexes in your C# source code.

First, use RegexBuddy to define a regex or retrieve a regexp saved in a RegexBuddy library. Rely on RegexBuddy’s clear regex analysis, which is constantly updated as you build the pattern, rather than dealing with the cryptic regex syntax on your own. Detailed help on that syntax is always only a click away.
If you copied a regex written for another programming language, simply paste it into RegexBuddy, select the original language, and then convert the regex to the .NET flavor used by C#.
If you created a new regular expression, test and debug it in RegexBuddy before using it in your C# source code. Test each regex in RegexBuddy’s safe sandbox without risking precious data. Quickly apply the regex to a wide variety of input and sample data, without having to produce that input through your application.
Finally, let RegexBuddy generate a source code snippet that you can copy and paste directly into Visual Studio or whichever IDE or C# code editor you use. Just choose what you want to use the regex for, and a fully functional code snippet is ready. You can change the names of variables and parameters to suit your naming style or the current situation, which RegexBuddy automatically remembers.
Don’t bother trying to remember which classes to use or which methods to call. And don’t worry about properly escaping backslashes and quotes. Just tell RegexBuddy what you want to do, and you will get the proper C# code straight away. Anything can be done: testing a string for a match, extracting search matches, validating input, search-and-replace, splitting a string, etc. Choose whether to create a reusable regex object for best runtime performance, or whether to use a one-line convenience function for maximum source code readability. RegexBuddy wraps its code with the proper try..catch statements, so you will never get unhandled exceptions out of the blue.
RegexBuddy also has specific support for the Visual Studio 2012 (and later) IDE. Since 2012 the IDE also uses the .NET regex flavor. But it does not support any regex options other than case insensitivity, which is on rather than off by default. RegexBuddy takes care even of such minor details. Create and test your regex in RegexBuddy with the same limitations as the IDE, or create it for C# first and then have RegexBuddy convert it for use in the Visual Studio IDE.
“I am a .Net developer with a decent working knowledge of regular expressions. I have found RegexBuddy to be an incredible tool because its debugging features allow me to tinker with a pattern until it works correctly with my actual data. Its graphical nature allows me to build a pattern a piece at a time and see what is working and not working. This empowers me to use regular expression methods such as Split or Replace to greatly simplify my code in places where I would otherwise need to do extensive byte by byte loops. Besides being an outstanding value for the money, email tech support is outstanding! Additionally, the tutorial itself is worth the price of the product. If you only use regular expressions once in 5 years this product would still be an outstanding value for your money!”
