RegEx validation for numbers only with a minimum length

Question

so i have this reg ex

0*[0-9]\d*

which accepts numbers only how would i, make it to accepts numbers only but have a minimum input of 5 numbers?

Solution 1

I this will do what you're wanting.

^\d{5,}$

Solution 2

Here's a template for you:

<expression>{length}
<expression>{min,}
<expression>{min,max}

In your case it will be:

\d{5,}

See the sandbox.

Solution 3

To specify the minimum ammount of symbols use {n,} where n is 5 in your example, so regex would be \d{5,}

String pattern = @"\d{5,}";
var result = Regex.Match("12345", pattern);

Doesn't this mean exactly 5? However OP asks for at least 5.

thank you sir this is what im looking for i just need to add a comma after the 5, one quick question what does $ mean?

[abatishchev]

@AsshO.Le: ^ begin of line, $ end of line.

If you actually want to make it mean "exactly 5" then use Bobby's original answer which he edited to properly answer the above question: ^\d{5}$ ...Adding the comma makes it minimum of 5 or greater
