-U回傳 else echo 陳述句，我不知道為什么。如果似乎忽略了我的第一個 if 陳述句，其他一切都有效。檔案夾導航的腳本函式。-U應該回傳 /users/username 目錄。在此先感謝您的幫助。
function display-path {Get-ChildItem Env:Path }
function folder {
[CmdletBinding(DefaultParameterSetName='Default')]
param(
[Alias('u')]
[Parameter(ParameterSetName='User')]
[switch] $Username
,
[Alias('s')]
[Parameter(ParameterSetName='Scripts')]
[switch] $Scripts
,
[Parameter(ParameterSetName='Desktop')]
[Alias('d')]
[switch] $Desktop
,
[Alias('h')]
[Parameter(ParameterSetName='help')]
[switch] $Help
,
[Alias('r')]
[Parameter(ParameterSetName='root')]
[switch] $root
)
$targetFolder =
if ($Username) {
$targetFolder = '\user\username'
}
if ($Scripts) {
$targetFolder = '\Desktop\Scripts'
}
elseif ($Desktop) {
$targetFolder = '\Desktop'
}
if ($root) {
$targetFolder = 'c:\'
}
else {
echo "
-H Display help. This is the same as not typing any options.
-U Change to the 'Username' directory
-S Change to the 'scripts' directory
-D Change to the 'desktop' directory"
}
Push-Location -LiteralPath $targetFolder
}
編輯： 這是用不起作用的 else if 陳述句更新的代碼，它忽略了第一個 if 陳述句。

如果您希望引數做一些互斥的事情并僅在未指定時才顯示幫助，您需要將所有檢查鏈接在一個if ... elseif ... elseif ... else鏈中：
if ($Username) {
$targetFolder = '\user\swmur'
}
elseif ($Scripts) {
$targetFolder = '\Desktop\Scripts'
}
elseif ($Desktop) {
$targetFolder = '\Desktop'
}
elseif ($root) {
$targetFolder = 'c:\'
}
else {
echo "
-H Display help. This is the same as not typing any options.
-U Change to the 'Username' directory
-S Change to the 'scripts' directory
-D Change to the 'desktop' directory"
