if your 12345 is an integer then you don't have to Convert.ToInt32(a) in the format, but if it's a string then you will, or else the leading 0's will not come through

<div class="content wysiwyg-content">
I am looking to prepend 10-x #s of &nbsp;0's to a string if its lenth is less than 10 and has a length x.<br />
<br />
so if I have 12345 I want to end up with 0000012345.<br />
<br />
What a short and sweet way of doing this? :)<br />
<br />
Thanks.

prepend a string to an exisiting 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).
