Question

我有这个脚本

#Change hostname
[void][System.Reflection.Assembly]::LoadWithPartialName('Microsoft.VisualBasic') 
Write-Host "Change hostname " -NoNewLine
$ComputerName = [Microsoft.VisualBasic.Interaction]::InputBox('Insert the desired computername:', 'Change hostname') 
Write-Host "- DONE" -ForegroundColor DarkGreen -BackgroundColor green -NoNewline
Write-Host " hostname = $ComputerName "
Rename-Computer -NewName $ComputerName

当计算机名称获取空格时，它会失败导致主机名无法包含空格。我可以阻止表单有任何空格，或者有人知道如何在为重试创建错误时返回到输入框

使用do { $ComputerName = [Microsoft.VisualBasic.Interaction]::InputBox('Insert the desired computername:','Change hostname') } while ($ComputerName -match "\s")循环并检查输入没有任何空格可以解决您的问题，这将重新提示，直到输入有效的主机名，如果您想要检查任何错误：

do{}while()

非常满意最终结果，非常感谢

#Change hostname
Write-Host "Change hostname " -NoNewLine
do{
    $Failed = $false
    Try{
        $ComputerName = [Microsoft.VisualBasic.Interaction]::InputBox('Insert the desired computername:', 'Change hostname') 
        Rename-Computer -NewName $ComputerName -ErrorAction Stop
        Write-Host "- DONE -" -ForegroundColor DarkGreen -BackgroundColor green -NoNewline
        Write-Host "Hostname = $ComputerName" -ForegroundColor DarkGreen -BackgroundColor yellow
    } catch { $Failed = $true }

} while ($Failed)

#Change workgroupname
Write-Host "Change Workgroup " -NoNewLine
do{
    $Failed = $false
    Try{   
        $WorkGroup = [Microsoft.VisualBasic.Interaction]::InputBox("Insert the Workgroupname:", 'Change WorkGroupName', 'werkgroep') 
        Add-Computer -WorkGroupName $WorkGroup -ErrorAction Stop
        Write-Host "- DONE -" -ForegroundColor DarkGreen -BackgroundColor green -NoNewline
        Write-Host "Workgroup = $WorkGroup" -ForegroundColor DarkGreen -BackgroundColor yellow
    } catch { $Failed = $true }
} while ($Failed)

Powershell试试Catch并重试？
