I tried regex [^(\d{12})$] to exclude 12 digits in any place in the sentence but it exclude any number.
example: test1234testing123131333231l:ast
I tried regex [^(\d{12})$]
example: test1234testing123131333231l:ast
matches any character except numbers:
matches : test , testing , l:ast
not match : 1234 , 123131333231
while I need to exclude "123131333231" only, kindly provide your support

I am trying to create a regular expression pattern in C# which allow you to have
next pattern: _DXX at the end of your .
Example :
04R5714A_D15 is correct
04R5714A_D05 is incorrect
04R5714A_D5 is correct
I tried : .*_D([1-9]{1}[0-9]?) but it didn't work :
.*_D[1-9]\d?$ should work for you.
Demo
.* catches everything up until your underscore
_D is a literal match
[1-9] matches one number in that range
\d? matches 0 or 1 single number (0-9)
$ is the end of the string

Regular expression for not allowing spaces in the input field

I'm trying to use regex which checks only two things
Minimum 10 characters (No Max)
No whitespace allowed
I'm able to check minimum 10 chars with #"^[a-zA-Z0-9]{10,}$" and disallow white space with ^[^0-9 ]+$
Now the problem is, how to combine both of these and allow everything(alphanumeric including special characters) except white space
You could try to use a simpler regex pattern just to accept anything that is not a white-space: ^\S{10,}$
\S - matches any non-white-space character. More details here: https://learn.microsoft.com/en-us/dotnet/standard/base-types/regular-expression-language-quick-reference

How to add hyphen to regex
(1 answer)
Closed 4 years ago.
I have the below regex, which currently allows '_' but not '-'.
string validCharacters = #"^\w+$";
Regex.Match(componentName, validCharacters);
But I want to also to include '-' as a valid character. The '-' can be at any place in the string. i,e: first,last,middle,after '_' etc.
Below are the few test cases:
"DTD_rtop-234"
"DTD-rtop_234"
"-DTD_rtop-234"
"DTD_rtop-234-"
"DTD_-rtop-234"
Any help will be much appreciated.
Combine the - character with the \w characters in a single character class:
[-\w].
Your desired regex is therefore:
^[-\w]+$.

I need to detect following format when I enter serial number like
CK123456.789
I used Regex with pattern of
^(CV[0-9]{6}\.[0-9]{3}
to match but if I enter
CK123456.7890
it still able to proceed without flagging error. Is there a better regular expression to detect the trailing 3 digits after '.'?
Depending on how you use the regular expression matcher, you might need to enclose it in ^...$ which forces the pattern to be the whole string, i.e.
^CK[0-9]{6}\.[0-9]{3}$ (Note the CK prefix).
I've also removed your leading (mismatched) parenthesis.
