Powershell -进程测试文件是否锁定，然后用计数器锁定文件？

$file = "C:\path\to\file.txt"
$locked = $false

try {
    $stream = [System.IO.File]::Open($file, 'Open', 'ReadWrite', 'None')
    $stream.Close()
} catch {
    $locked = $true
}

if ($locked) {
    Write-Host "The file is locked."
} else {
    Write-Host "The file is not locked."
}

$lockFile = "C:\path\to\lock.txt"
$lockCounter = 0

# 加锁
function Lock-File {
    while ($true) {
        if ((Test-Path $lockFile) -eq $false) {
            New-Item -ItemType File -Path $lockFile | Out-Null
            break
        }
        Start-Sleep -Milliseconds 100
    }
}

# 解锁
function Unlock-File {
    Remove-Item -Path $lockFile -Force
}

# 计数器加锁
function Increment-Counter {
    Lock-File
    $lockCounter++
    Unlock-File
}

# 计数器减锁
function Decrement-Counter {
    Lock-File
    $lockCounter--
    Unlock-File
}

# 使用计数器锁定文件
Increment-Counter
# 执行文件操作
# ...
Decrement-Counter
