我有一个脚本等待用户输入,然后取决于他们按什么做什么。但问题是,无论他们按什么脚本,脚本都会继续(但如果它不是它预期的两个键中的一个,我只会得到错误)。这是我正在研究的狙击手
Write-Host "What do you want to do next?" -nonewline
Write-Host "
u - Search for another user
c - Enter a computer name
"
# Prompt for an action
Write-Host ">> Select shortcut action: " -nonewline
$key = [Console]::ReadKey()
$value = $key.KeyChar
switch($value) {
c { $c = Read-Host "Enter computer or IP"}
u { $u = Read-Host "Enter user" }
}
# now we continue on with the code depending on what was pressed
我喜欢的是,如果按下c
或u
之外的任何内容,则告诉用户该用户不是有效密钥并返回到此snippint的顶部并提示用户再次采取下一步行动。
答案 0 :(得分:2)
只需将代码包装在do-while
循环中,只要$value
不是c
或u
,就会继续执行此代码:
do
{
$key = [Console]::ReadKey($true)
$value = $key.KeyChar
switch($value) {
c { $c = Read-Host "Enter computer or IP"}
u { $u = Read-Host "Enter user" }
}
}
while ($value -notmatch 'c|u')
