我想映射網路。如果映射失敗，我需要使用重試，并且最大重試 5 次。我已經嘗試過這種方式，但我不知道如何添加最大重試次數。
Do{
Try{
$net = new-object -ComObject WScript.Network
$net.MapNetworkDrive("$Directory", "\\IP\$Folder", $False, "$Server\$SQL", "$pass")
$Message = "Mapping : " $Directory "Successful"
Write-Host $Message
}
Catch{
$Message= "Mapping : " $Directory " Fault" " $_"
Write-Host $Message
}
}While($? -ne $true)
任何人都可以幫助真正感激。謝謝

有很多方法可以解決這個問題，這里是一種使用腳本塊的方法，請注意，此示例僅有效，因為您使用Write-Host的是哪個輸出轉到資訊流，并且除非重定向 ( 6>&1)，否則不會捕獲它的輸出。
$action = {
Try
{
$net = New-Object -ComObject WScript.Network
$net.MapNetworkDrive(
"$Directory", "\\IP\$Folder", $False, "$Server\$SQL", "$pass"
)
$Message = "Mapping : " $Directory "Successful"
Write-Host $Message
$true # => if everything goes right $result = $true
}
Catch
{
$Message = "Mapping : " $Directory " Fault" " $_"
Write-Host $Message
$false # => if fails $result = $false
}
}
$maxRetries = 5
do { $result = & $action } # do this
until (-not --$maxRetries -or $result) # until $result is True OR
# $maxRetries reaches 0
老實說，一個更簡單的選擇：
$maxRetries = 5
1..$maxRetries | ForEach-Object {
if( & $action ) { break } # => if action = True stop the loop
}
