Hi Experts,<br />
<br />
The following regular expression validates the times in the format: &quot;11:47AM&quot; .... How to I change it to validate &quot;11:47 AM&quot; (The space is important because it needs to be in DateTime.ToShortTimeString<wbr /> format.<br />
<br />
Thanks,<br />

RegEx for ShortTime string

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).
