Matching @ Symbol in String

PowerShell Help
1

All,

I am using Get-WebConfigurationProperty to pull the values in the “requestquerystringsequence” section. I am then testing to ensure that the “@” symbol is present as one of the values in that collection. I can do this successfully with other characters “;,://” etc., but it fails with “@”.

I am guessing Powershell is reading this as a 'here string" or some other special character. I have tried escaping it with \ and `, to no avail. Any ideas?

[pre]

$Arr = “@”

(Get-WebConfigurationProperty -Filter system.webserver/security/requestfiltering/denyquerystringsequences/add -PSPath ‘MACHINE/WEBROOT/APPHOST’ -Name sequence | Select Value) -match $Arr

[/pre]

Thanks,

Des

Have you tried using single quotes?

(Get-WebConfigurationProperty -Filter system.webserver/security/requestfiltering/denyquerystringsequences/add -PSPath 'MACHINE/WEBROOT/APPHOST' -Name sequence | Select Value) -match '@'

If it is the variable that contains Special Characters this should work. Within the @" "@ delimiters variables and sub-expressions will get expanded, but quotes and other special characters are treated as literals.[/quote]

$SpecialCharacters = @'
& "C:\Program Files\7-Zip\7z.exe" u -mx5 -tzip -r "$DestFileZip" "$DestFile"
'@
$SpecialCharacters

It should work with both single and double quotes, use Select-Object -ExpandProperty Value to expand it as a string.

Thank you @kvprasoon. Using the -ExpandProperty with the Value, solved the problem.
