I need a regex to match any p tag that has one or more strike tags inside it.
For example:
<p><strike>Match this</strike></p>
<p style="">Hey! <strike>Match this</strike> also</p>
<p><strike>Match this</strike> entire <strike>p tag</strike></p>
Thanks!

You can use this regex
<p[^<>]*>.*?<strike>.*?</p>
But parsing an html with regex is not recommended method.
Instead use an html parser like htmlagilitypack..
You can use this code to retrieve it using HtmlAgilityPack
HtmlDocument doc = new HtmlDocument();
doc.Load(yourStream);
//strikeNodes contains all the p nodes
var strikeNodes = doc.DocumentNode.SelectNodes("//p[strike]");
//pText contains all p nodes in textual format
List<string> pText= doc.DocumentNode.SelectNodes("//p[strike]").Select(x=>x.OuterHtml);

The code:
'Files' is a List<string> and _indx is an int.
label22.Text = files[_indx];
For example in 'files' in index[0] I have this string:
D:\New folder (45)\converted.avi_Automatic\Lightning 0 Length 2 [91 - 93]\000091.bmp
But instead in label22.Text I want it to show me only '000091.bmp' without the rest of the directory path.
How can I do it ?

Use Path.GetFileName:
label22.Text = Path.GetFileName(files[_indx]);

I believe you are looking for Path.GetFileName():
label22.Text = Path.GetFileName(files[_indx]);

Path.GetFileName(fileName) returns the file name without the directory.

The simplest way is
Path.GetFileName(files[_indx]);

I want to retrieve a number from a string wherever the number starts with 8,9 or 6 and length of the number should be 8 OR 9 Characters. E.g 92000000,9200 0000,9200-0000.

How about this: (?<!\d)([896]\d{3})(?:[-\s]?)(\d{4})(?!\d).
The (?:[-\s]?) eats the optional delimiters space or dash as a non-capturing group.
You get your number by concatenating the match groups 1 and 2:
var input = new string[] {
"81000000", "92000000", "9200 0000", "9200-0000"
};
var regex = new Regex (#"(?<!\d)([896]\d{3})(?:[-\s]?)(\d{4})(?!\d)");
foreach (var str in input) {
var match = regex.Match (str);
Console.WriteLine ("TEST: {0} {1} - {2}", str, match.Success,
match.Groups [1].Value + match.Groups [2].Value);
}
I have also tried (?<!\d)([896]\d{3}(?:[-\s]?)\d{4})(?!\d) and that won't remove the delimiter character from the match result.

Try the below regex:
(?<!\d)[896]\d{3}([- ]?)\d{4}(?!\d)
Try to solve using Regexpal from next time.
Cheers.

I want to find the regex pattern to find the text between a string and a char and replace spaces in the text with _.
Example. < Node Type="Text">Event Log < /Node >
Expected output : Event_Log
Thanks in advance. Please help.

string s = "here is my text $$$ Hello World </stop>";
Match m = Regex.Match(s, "(\\$[^<]*)<");
if (m.Success)
{
Console.WriteLine(m.Groups[1].Value);
}

string str = "$$$ Hello World </stop>";
string sPattern = "[\\$]{3}([\\d\\s\\w]*)</stop>";
Match m = Regex.Match(str, sPattern, RegexOptions.IgnoreCase);
if (m.Success) {
Console.WriteLine(m.Groups(1));
}
Converted from VB code and not tested after but should be ok.

Assuming the example is correct and the text of your question wrong, you need:
\$+[^$<]*(?=<)
If it's the other way around, try this:
(?<=\$+)[^$<]*<
BTW, all questions like this can be more easily answered using a tool like this online regex tester.

C# check line number of stringreader [closed]

How do I check if the string reader has passed a certain line number, or has passed a line number which contains some text? I put this in the line processing code of a string reader:
if (currentline.Contains("123"))
currentbank = "123";
else if (currentline.Contains("456"))
currentbank = "456";
else if (currentline.Contains("789"))
currentbank = "789";
I want to change the contents of a string based on what range of line numbers it is in, with my code it always gives 123. Like for example if it's from lines 10-20 (or from 123 to 456) then the string should have 123, 20-30 (or 456 to 789) it should have 456 and 30-40 have 789. How can I do this using a StringReader?

Fixed it myself, problem being I used upper case (e.g. TEST) instead of lower case.
