在批处理文件中嵌入 powershell 脚本

Question

Can you teach me how to embed/Encode this within batch file?

Get-Process | Where-Object { $_.Name -eq "Sample1" } | Select-Object -First 1 | Stop-Process


$app = Get-WmiObject -Class Win32_Product | Where-Object {
 $_.Name -match "Sample1" {

$app.Uninstall()

There's really no reason to ever write a batch/powershell hybrid when using either one or the other works just fine, but there's a technique that was developed on DOSTips that you can use to embed Powershell in a batch script:

<# :

@echo off
setlocal
set "POWERSHELL_BAT_ARGS=%*"
if defined POWERSHELL_BAT_ARGS set "POWERSHELL_BAT_ARGS=%POWERSHELL_BAT_ARGS:"=\"%"
endlocal & powershell -NoLogo -NoProfile -Command "$_ = $input; Invoke-Expression $( '$input = $_; $_ = \"\"; $args = @( &{ $args } %POWERSHELL_BAT_ARGS% );' + [String]::Join( [char]10, $( Get-Content \"%~f0\" ) ) )"
goto :EOF

Get-Process | Where-Object { $_.Name -eq "Sample1" } | Select-Object -First 1 | Stop-Process


$app = Get-WmiObject -Class Win32_Product | Where-Object {
 $_.Name -match "Sample1" {

$app.Uninstall()

The batch code goes into a powershell multiline comment, calls itself with the powershell interpreter, then exits.
