Hello gsdevEE,<br />
<br />
Would the following be valid:<br />
<br />
----<br />
&nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br />
1234<br />
abcd<br />
<br />
They all meet the written criteria, but look somewhat different from your only example of a valid code...<br />
<br />
Regards,<br />

I think you meant:<br />
<br />
[a-zA-Z0-9 -]{1,12}<br />

elimesika,

I think you meant:

[a-zA-Z0-9 -]{1,12}

Hi &nbsp;gsdevEE;<br />
<br />
This regex pattern should do what you want.<br />
<br />
Fernando<br />

<pre><code id="code-480651">^[a-zA-Z0-9-]{1,12}$
</code></pre>
</div>


Hi  gsdevEE;

This regex pattern should do what you want.

Fernando


^[a-zA-Z0-9-]{1,12}$


<div>
<div class="content wysiwyg-content">
Regex for 12 alphanumeric characters, a dash &quot;-&quot;, and 1 to 12 characters in length, including whitespace.<br />
<br />
<br />
So abc-12345678 would be valid<br />
<br />
abc-123456789 would be invalid<br />
<br />
And any string including any characters other than these would be invalid.<br />
<br />
I cant figure the regex out. &nbsp;Im sure there is someone who can get this quick, and I have too many bugs on my plate - thanks !<br />

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.

.NET Programming

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

A regular expression ("regex") is a sequence of characters that define a search pattern, mainly for use in pattern matching with strings, or string matching, i.e. "find and replace"-like operations. Regular expression processors are found in several search engines, search and replace dialogs of several word processors and text editors, and in the command lines of text processing utilities, such as sed and AWK. Many programming languages provide regular expression capabilities, some built-in, for example Perl, JavaScript, Ruby, AWK, and Tcl, and others via a standard library, for example .NET languages, Java, Python and C++ (since C++11). Most other languages offer regular expressions via a library.
