Vista - $Variables into Regular expressions ?! help

05-07-2009

I've got a requirement to find a string in an array.
Simple! but I need to search on the string contained in 2 variables,

So basically I'm trying.

$SearchStr ="$SuppliedStr1*$SuppliedStr2"
$RegStr=[regex] $SearchStr

$ArrayToSearch | where { $_ -match $RegStr }

This appears to work OK, BUT I need to match where $SuppliedStr2 in
the End of the line in the array, so I guess I'm trying to add $ to
the end of the $RegStr... . But I can't get it to work!?

I'm sure this is easy for you guys that know what your doing!?
Thanks in advance, hope it makes sense!!!??

I'm not positive I'm understanding the question exactly, but does this work?
