C# - Understanding Regular Expression For Number Range
Jan 26, 2011
I'm trying to build up some regular expressions to validate some textbox controls. I have done some research and testing but cannot get this one working. Examples of what i am trying to create regular expressions for are as follows:
Range 0-45, 0 decimal places
Range 0-20, 2 decimal places
Range 16-65, 0 decimal places
Range 0-99, 2 decimal places
Range 0-1500000, 0 decimal places
Range 0-200, 1 decimal place
For 1 and 5 respectively, I have used
([0-9]|[0-9]d|45)$
([0-9]|[0-9]d|1500000)$
The first one I am having problems for is an age range of 16-65 (inclusive), where I want no decimal places. After a post on here (Regular expression to allow numbers between -90.0 and +90.0) I thought I could use the logic and get it sussed, but can't! The expression I got to was:
(d|([1-6][6-4]))|65

I want to validate a number by regular expression. Here is the requirement.
1- It should be between 1 and 200
2- maximum 2 floating point (e.g. 24.54 accepted but not 24.546)
3- the radix point can be either Dot or Comma (e.g. 29.45 - 29,45 both accepted)
4- can be intiger in this range also (e.g. 24 or 24.00)
Can anyone post an efficient regular expression for this?

I am trying to write a Regular Expression Validator to allow users to input any number (either positive or negative), except 0. I tried the followings but obviously they failed:
^[1-9-]{1,10}$ <= failed when the 2nd to n-th digit is 0
^d+$ <= failed to treat negative numbers as valid

I am splitting the phone number entered into two parts using regular expressions below
(^d{3}) - last 7 digits
d{7} - first 3 digits
This works fine if entered value is 1234567890 or 123-456-7890
and fails if value entered is 123 456 7890 (with spaces) or 123.456.7890
how to modify above expressions to trim (spaces and .)?

i have to check if an input string is valid based on the given regular expression.. this is the regular expression.
(a(bb+aaa+((ab)*bb+(aba)*aa)(a+b)*) + (b(aa+bbb+((ba)*aa+(bab)*bb)(a+b)*)
+ is an OR
* is a LOOP, it is optional, it may be done as many as a user wants.
i've tried many ways to solve the problem that my professor gave me but my knowledge isn't that enough to solve this problem..

I'm trying to use the validator to work on a email form to ensure that they enter a valid from email address. That part works. I also want to add to the expression the text that I pre-populate in the txtbox ("Enter your email address") so on postback, after sending the message, I can clear the fields and repopulate that box.
How do I add that wording to the current expression: w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*

<asp:RegularExpressionValidator ID="reg2" runat="server" ControlToValidate="rng2"
ValidationExpression="^[0-9]+" ErrorMessage="*Please Enter a Valid Number for Second Range."

I am using a regex to detect forum tags within posts, such as "[quote]text[/quote]" and then replace them with HTML formatting. I posted a question Forum tags. What is the best way to implement them? about a problem with nested tags.
I need this regex modified
string regex = @"[([^=]+)[=x22']*(S*?)['x22]*](.+?)[/(1)]";
Right now this matches an opening and closing tag, with match groups for the tag name, the tag content, and an optional value like the value after the equals in this forum tag [url=www.google.com]click me[/url].
What I need is for the expression to match the opening tag OR the closing tag and have a match group containing the tag name (including the '/' for the closing tag). I then want to iterate through them sort of like this:
Dictionary<string, int> tagCollection = new Dictionary<string, int>();
inputString = Regex.Replace(inputString, @"expression I'm asking for here",
match =>
{
[Code]....
So now, each tag is appended with a number and I could use the original regex to perform the tag functions and properly handle nested tags as separate tags.
