Filtering files with -notcontains

I'm trying to filter a file extension equal to .config and file name doesn't contains vshost in the name, so I run this script:

$files = dir
foreach($file in $files) {
    if($file.Name -notcontains 'vshost' -and $file.Extension -eq '.config') {
        Write-Host $file;
    }
}

But the output still contains files with vshost in the name:

foo.exe.config
foo.vshost.exe.config
foo2.vshost.exe.config

the expected output is:

foo.exe.config

What am I missing and how do I fix this?

-contains/-notcontains is used to check if a list contains an element. You can use the -like / -notlike or the -match operator.

In your sample you could use

$files = dir
foreach($file in $files) {
    if($file.Name -notlike '*vshost*' -and $file.Extension -eq '.config') {
        Write-Host $file;
    }
}

-notcontains is used to look for an item in an array, ex. $array -notcontains $singleitem. You need to use -notlike or -notmatch (regex-patterns). Ex.

if($file.Name -notlike '*vshost*' -and $file.Extension -eq '.config') {

or

if($file.Name -notmatch 'vshost' -and $file.Extension -eq '.config') {
