.NET Framework - how to compare in this situation

Asked By IT Staff

20-Jul-07 02:19 AM

$dictionary = @{}
$dictionary["v1.0."] = "Version 1.0"
$dictionary["v1.1"] = "Version 1.1"
$dictionary["v2.0"] = "Version 2.0"
$dictionary["v3.0"] = "Version 3.0"


$strComputer = $args[0]
$dir = dir "\\$strcomputer\admin$\microsoft.net\Framework"
$folders = $dir | where {$_.mode -match "d" -and $_.name -like "v*"} |
select name

foreach ($folder in $folders)
{
$folder
}
==============================================================

I want to do a $folder comparison with the $dictionary hash tables. If a
$folder name exists in  $dictionary hash tables, it will display the
$dictionary.values

How do it do that ?

I think -contains operator will accomplish ur problem and I believe there
are more effective solution for this problem.

just like :

PS C:\Documents and Settings\Eden> $hash = @{}
PS C:\Documents and Settings\Eden> @($hash.keys) -contains 'a'
False
PS C:\Documents and Settings\Eden> $hash['a'] = "test"
PS C:\Documents and Settings\Eden> @($hash.keys) -contains 'a'
True
PS C:\Documents and Settings\Eden>

Use the containment operator -contains. Also use .psIsContainer instead of
.mode -match 'd'.
Here is the one-liner:

dir "\\$strcomputer\admin$\microsoft.net\Framework" | where
{$_.psIsContainer -and $_.name -like "v*" -and $dictionary.keys -contains
$_.name} | foreach {$dictionary."$($_.name)"}

The double quotes are not necessary in the foreach loop.

foreach {$dictionary.$($_.name)}

Perhaps i m not clear on my questions.

I want to list the remote machine directory and once found it will display
the VALUES.

Version 1.0
Version 1.1
etc

Part of the problem may be in the names you have in the dictionary.  For
instance on my machine the folders are
v1.0.3705
v1.1.4322
v2.0.50215
v2.0.50727
v3.0

Try this

$dictionary = @{}
$dictionary["v1.0"] = "Version 1.0"
$dictionary["v1.1"] = "Version 1.1"
$dictionary["v2.0"] = "Version 2.0"
$dictionary["v3.0"] = "Version 3.0"

$dir = dir "c:\windows\microsoft.net\Framework"
$folders = $dir | where {$_.mode -match "d" -and $_.name -like "v*"} |
select name

Foreach ($folder in
$folders){$dictionary[$folder.Name.Tostring().SubString(0,4) ]}

You will need to alter the $dir = ....    line for remote machines

$dictionary = @{}
$dictionary["v1.0.3705"] = "Version 1.0"
$dictionary["v1.1.4322"] = "Version 1.1"
$dictionary["v2.0.50727"] = "Version 2.0"
$dictionary["v3.0"] = "Version 3.0"

I can create the hash table to pre-determine the folder name.

However after running the directory listing, it does not display the
dictionary.values. What i need is the values not keys.

Is this what you want?

dir C:\windows\Microsoft.net\Framework | where {$dictionary.keys -contains
$_} | foreach {$dictionary["$_"]}

Another approach would be:

$dictionary = @{}
$dictionary.'v1.0.3705' = 'Version 1.0'
$dictionary.'v1.1.4322' = 'Version 1.1'
$dictionary.'v2.0.50727' = 'Version 2.0'
$dictionary.'v3.0' = 'Version 3.0'

gci $env:windir\Microsoft.net\Framework | ForEach { $dictionary."$_" }

If usage of the dictionary isn't essential:

gci $env:windir\Microsoft.net\Framework\v?.?* |
where {$_.psIsContainer}|
ForEach {write-Host "Version "$_.name.SubString(1,3)}

or

gci \\$strComputer\admin$\Microsoft.net\Framework\v?.?* |
where {$_.psIsContainer} |
ForEach {write-Host "Version "$_.name.SubString(1,3)}
