.NET Regex is a tool for testing .NET regular expressions.
Silverlight is used if available, otherwise Ajax calls made to the server (the icon
in the top-right indicates which). With Silverlight auto mode is
used by default — the regular expression is automatically applied to the test input
after every keystroke. Auto mode can be disabled by unchecking the checkbox. When auto
mode is disabled either click on the Test button or press CTRL-Enter to run the test.
The regular expression and test input text areas can be resized
by dragging the handles.
UI settings — auto-mode, text size, textbox heights — are stored automatically.
Regular expression text, test input text, and options, are stored in browser storage
when the Save button is clicked.
The amount of text that can be stored depends on the browser.
