Help decoding a regular expression

Question

I am supporting a new application and I do not use regex very often and was hoping someone could decode the following as well as let me know if a string containing a period would pass.
Regex r = new Regex("^\\s*[a-zA-Z,\\s]+\\s*$");

No it will not pass validation if there is period in string .

How can I modify this expression to accept a period(.) in any location in the string? Regex r = new Regex ( ^\s*[a-zA-Z\s]+\s*$ );

Bill · Answer

Would a period in the string pass validation?

Your Decoded RegEx is As Follow 1 .Your Regex will First match ' \ ' Litrely 2. Then You can Write character 's' unlimited Number of Times 3. After that You can Write Any Number of Characters From A-Z or a-z or \ or '  ' (comma) or 's' 4. Then You have to Write character 's' Unlimited number of Time 5. and Your String Should be End With ' \ ' or '\ssss' for example your regex will Find Match of below String \sabcdefg\ssss\ Thats the Full decode of Your regEx . Happy Coding :)
