PowerShell实现动态获取当前脚本运行时消耗的内存（powershell脚本语法）干货满满

$script:last_memory_usage_byte=0

function Get-MemoryUsage
{
$memusagebyte=[System.GC]::GetTotalMemory(‘forcefullcollection’)
$memusageMB=$memusagebyte / 1MB
$diffbytes=$memusagebyte – $script:last_memory_usage_byte
$difftext=”
$sign=”
if ( $script:last_memory_usage_byte -ne 0 )
{
if ( $diffbytes -ge 0 )
{
$sign=’+’
}
$difftext=”, $sign$diffbytes”
}
Write-Host -Object (‘Memory usage: {0:n1} MB ({1:n0} Bytes{2})’ -f $memusageMB,$memusagebyte, $difftext)

# save last value in script global variable
$script:last_memory_usage_byte=$memusagebyte
}
