Powershell: Unable to find type [System.IO.Compression.ZipArchiveMode]: TypeNotFound error
The error message you encountered indicates that PowerShell was unable to find the type [System.IO.Compression.ZipArchiveMode]
. This error typically occurs when the required assembly or namespace is not loaded or not available in the current session.
To resolve this issue, you can try the following steps:
Check PowerShell version: Verify that you are using a version of PowerShell that supports the
System.IO.Compression
namespace. TheZipArchiveMode
type is available in PowerShell 5.0 and later versions. You can check your PowerShell version by running the command$PSVersionTable.PSVersion
.Import the required assembly: If you are using a compatible version of PowerShell, you might need to manually import the required assembly before using types from the
System.IO.Compression
namespace. Run the following command to import the assembly:powershellAdd-Type -AssemblyName System.IO.Compression.FileSystem
This command imports the
System.IO.Compression.FileSystem
assembly, which provides access to theZipArchiveMode
type.Verify namespace and type: Double-check the namespace and type name to ensure they are correct. The correct namespace is
System.IO.Compression
and the correct type name isZipArchiveMode
.Here's an example of how you might use the
ZipArchiveMode
type:powershell$zipArchiveMode = [System.IO.Compression.ZipArchiveMode]::Create
This code creates a variable
$zipArchiveMode
and assigns it the value of theCreate
enumeration member from theZipArchiveMode
type.
If the above steps don't resolve the issue, it's possible that the required assembly is missing or corrupted. In such cases, you may need to reinstall or repair the .NET Framework on your system. Additionally, ensure that you have the necessary permissions to access the assembly and that your PowerShell execution policy allows loading assemblies.
If the problem persists, providing more information about the specific PowerShell code you are executing would be helpful in troubleshooting the issue further.
