写首选项

消息可以用;

Write-Verbose "Detailed Message"
Write-Information "Information Message"
Write-Debug "Debug Message"
Write-Progress "Progress Message"
Write-Warning "Warning Message"

每个都有一个偏好变量;

$VerbosePreference = "SilentlyContinue"
$InformationPreference = "SilentlyContinue"
$DebugPreference = "SilentlyContinue"
$ProgressPreference = "Continue"
$WarningPreference = "Continue"

首选项变量控制如何处理消息和后续执行脚本;

$InformationPreference = "SilentlyContinue"
Write-Information "This message will not be shown and execution continues"

$InformationPreference = "Continue"
Write-Information "This message is shown and execution continues"

$InformationPreference = "Inquire"
Write-Information "This message is shown and execution will optionally continue"

$InformationPreference = "Stop"
Write-Information "This message is shown and execution terminates"

通过设置可以控制消息的颜色为 Write-Error;

$host.PrivateData.ErrorBackgroundColor = "Black"
$host.PrivateData.ErrorForegroundColor = "Red"

类似的设置可用于 Write-Verbose，Write-Debug 和 Write-Warning。
