Heres the PS.

# cd to the agent artifacts directory (where the zip file exist)
cd $env:Agent_ReleaseDirectory
cd _Your.Project-CI\drop
$fileToEdit = "web.config"


[Reflection.Assembly]::LoadWithPartialName("System.IO.Compression.FileSystem");
# Open zip and find the particular file (assumes only one inside the Zip file)
$zipfileName = dir -filter '*.zip'

$zip =  [System.IO.Compression.ZipFile]::Open($zipfileName.FullName,"Update")


$configFile = $zip.Entries.Where({$_.name -like $fileToEdit})

# Read the contents of the file
$desiredFile = [System.IO.StreamReader]($configFile).Open()
$text = $desiredFile.ReadToEnd()
$desiredFile.Close()
$desiredFile.Dispose()

$contentToAdd1 = @'
    <system.webServer>
    <modules>
    <albert>
    <remove name="WebDAVModule" />
    </modules>
'@
#$text[3] = $text[3] -replace '<system.webServer>',$contentToAdd1
$text = $text -replace '<system.webServer>',$contentToAdd1
 
#update file with new content
$desiredFile = [System.IO.StreamWriter]($configFile).Open()
$desiredFile.BaseStream.SetLength(0)

# Insert the $text to the file and close
$desiredFile.Write($text)
$desiredFile.Flush()
$desiredFile.Close()

# Write the changes and close the zip file
$zip.Dispose()

CodePudding user response：

Please add a $Sourcefolder in your script like below to check:

$Sourcefolder= "$env:Agent_ReleaseDirectory\_Your.Project-CI\drop"

$zipfileName = dir $Sourcefolder -filter '*.zip'

And change Open($zipfileName.FullName,"Update") to OpenRead($zipfileName.FullName):

$zip = [System.IO.Compression.ZipFile]::OpenRead($zipfileName.FullName)
