Regex Expression - HELP!

[mortovski]

Hi there,

I'm having trouble using the C# regex function and any help would be appreciated!

Here's a snippet of the code I'm using:

matches = regex.Matches(txtInput.Text,@txtRegEx.Text,RegexOptions.IgnoreCase);
foreach (Match NextMatch in matches)
            {
                rtbOutput.Text += "Match Found\n";
            }
 

From what I've read you use /b to demarcate the start and end of a word so that /bhop/b won't match hope or shop.

Now if I do this:

txtInput = Foo. 
txtRegEx = /bFoo/b

The code snippet above is picking up the period as part of the word - meaning I get a match when I don't want one.

But if I do this:

txtInput = Foo.
txtRegEx = b/Foo/./B 

It seems to work, but then this doesn't work:

txtInput = Foo.
txtRegEx = b/Foo/./b

Can anyone tell me what I'm doing wrong? Essentially I want to know what to wrap around my search text to make sure that the same piece of code will treat all of these differently:

Foobar
Foo.
Foo
Fo
Fo.

I'm sure it's really straightforward - but I've been searching the web for answers and can't seem to get to the bottom of it!

Thanks,
Peter
