I was trying regular expression
to accept only numbers and it should not allow to accept more than ten
^[]0,10]{0,10}$
This matches just this range of numbers: [0-9]
^([0-9])$
And then you can use $1 if you need to replace is with something else ...
Or also you can use \d instead of [0-9] like this:
^(\d)$
And if you want to accept 10, you have to use |. Some thing like this;
^(\d|10)$
As I said, this ^ regex accept both this range [0-9] and 10.
You can try this one:
^[0-9]{0,10}$

I have a pattern (pattern) and I want to exclude this characters in string 'test' and find all holes in this expression. Like test, but this characters will be random
For the string 'test' I expect 'test' which is not matched by pattern ()
You could use Regex#Match here:
Regex regex = new Regex(#"(XZ|RP(?!ROD)|R|DP(?!ROD)|D|ST[\d]?|WO)");
Match match = regex.Match("testRPRODRRPWO");
if (!match.Success)
{
Console.WriteLine("input does not contain pattern");
}

I'm learning about Regex in C#, I've written the codes to check a valid day but Regex.Match is always false.
var pat = #"(today|tomorrow|yesterday)((?:\s*[+-]?\s*\d+\s*[dwym])*)"; // Can not change
Match match = Regex.Match(value, pat);
the match.Success is always false (value = 2017-07-07)
Which format can match with that pattern?
What are you actually trying to achieve? From the looks of it you are trying to match either some text (today/tomorrow/yesterday), or a date in a specific format?
Try this:
(today|tomorrow|yesterday|\d{4}-\d{2}-\d{2})
Try using a regular expression designer as well. I use Rad Software Regular Expression Designer 1.4.

Good Afternoon,
I would like a regex to validate if the user typed two names or more and not only the first name, as in this example:
Ex: Fabrício (no match)
Ex:
Fabrício Oliveira (match)
Fabrício Oliveira Xavier (match)
Note: The expression must contain accents
Here's a Regex that only relies on a whitespace separator:
^\S+(\s\S+)+$
It makes these assumptions:
No name has a space, tab, or newline in it
Names are separated by exactly one space, tab, or newline
* this is based on #juharr's comment but with the parentheses to allow more than two names.
Edit: You can play around with this Regex here https://regex101.com/r/nS3hN8/1
Edit2: Added the beginning and ending anchors to the regex
Try this regular expression which matches two any length words separated by a space:
new Regex(#"\w+ \w+");
Really you could just use this:
if (Regex.Match(stringname, #"\w+\s\w+").Success)

Is it possible to concatenate two sub strings from a input string using Regex
Example : Input string "ABTTPQR 00100300250000" and I want take first two characters "AB" and first 9 digits "001003002" and concatenate these two string to one "AB001003002"
Much shorter variation using references:
Regex.Replace("ABTTPQR 00100300250000", #"^(\w{2})\w*\s(\d{9})\d+$", #"$1$2")
// = "AB001003002"
You can do as follows :
Regex regex = new Regex(#"(\w{2})\w*\s(\d{9})\d*");
var matches = regex.Matches("ABTTPQR 00100300250000");
String output = matches[0].Groups[1].Value + matches[0].Groups[2].Value;
//AB001003002
Regex Explanation:
(\w{2})\w*\s(\d{9})\d*
The (\w{2}) will match the first 2 chars, then it will look for more chars and a space \w*\s then it will match first 9 digits (\d{9}) and then will look for more digits \d*.
The () captures the matches into groups which are accessed in c# like shown in code sample: matches[0].Groups[1].Value for group 1 (chars) and matches[0].Groups[2].Value for group 2 (digits)

I need a regular expression for the following please
zzz abc_2006073122
zzz abc_def_2006073122
zzz abc_def_ghi_2006073122
I need to get the first 8 digits of the date (20060731) but i may have several _ parts before that so not quite sure what expression will get me what i need.
Thanks
string str = #"zzz abc_def_ghi_2006073122";
Regex reg = new Regex(#"^[a-zA-Z_ ]*_(?<someNamedGroup>\d{8})");
var match = reg.Match(str);
var result = match.Groups[1].Value;
The Regex is something like:
([0-9]{8})(?:[0-9]{2})$
Meaning: anchored to the end of the string, 8 digits to "take", 2 digits to ignore.
If you can't use the end of the line as anchor, you can try this:
(?:_)([0-9]{8})(?:[0-9]{2})
Meaning: a _ followed by 10 digits. Only 8 of these digits will be captured.
