Regular Expression (match word + some number) C#

Sorry doing this the fast way of asking all the regex experts out there :)

What regex for C# can I use that matches the end of a word + some number

Eg. End of string matches with "Story" + 0 or more numbers

"ThisIsStory1"    = true
"ThisIsStory2000" = true
"ThisIsStory"     = true
"Story1IsThis"    = false
"IsStoryThis1"    = false

Hope this makes sense

A regular expression that I could plug into C# would be fantastic.

Thanks

A .NET regex that meets your criteria is:

Story\d*\b

(Use the Regex.IgnoreCase option if desired.)

\b matches the word boundary, so Story1IsThis will not match, but ThisIsAStory1 will. The word 'Story' does not need to end the string, so the string "ThisIsAStory234 ThisIsNot" will match on Story234.

to match number of characters before story and then story???? use this:

"[A-Za-z]*(s|S)tory\d*$"

string compare = "story1withANumber";
Regex regex = new Regex(@"[A-Za-z]+Story[0-9]*");

if (regex.IsMatch(compare))
{ 
    //true
}

regex = new Regex("[0-9]");

if (regex.IsMatch(compare))
{ 
    //true
}

You'll need something like this Story[0-9]*$

So it matches for story (ignoring anything before it, you may need to add more), then for 0 or more numbers between story and the end of the string.

Try [A-Za-z]*Story[0-9]*.

If you want to check against a whole line, ^[A-Za-z]*Story[0-9]*$.
