PowerShell菜单输入选项后对应函数未调用循环刷新问题求助

• 类型不匹配：Read-Host返回的输入是字符串类型，代码中直接和数字1-9做等值比较，PowerShell严格类型匹配下会判定为不相等，因此if判断始终不通过，直接进入continue逻辑重新加载菜单
• 函数名不匹配：选项8绑定的调用函数名为Acronis-Images，但实际定义的函数名为Acronis，名称不一致会导致调用失败
• 输出被立即清屏覆盖：函数执行完成后下一次循环会立刻执行Clear-Host，用户看不到函数执行的输出内容

function PORII
{
    Write-Host " PORII was called"
}
function DXD-BODY

    Write-Host " DXD BODY was called"

}
function DXD-PTO

    Write-Host " DXD PTO was called"

    Write-Host " DXD TCF was called"
}
function FIS-SERVERS

    Write-Host " FIS SERVERS was called"

function SERVERS
{
    Write-Host " SERVERS was called"

function Acronis

    while ($true)

        Clear-Host

        $a = Read-Host -Prompt "`n Enter your option "
        # 输入转整数并校验范围
        if ([int]::TryParse($a, [ref]$opt) -and $opt -ge 1 -and $opt -le 9)
        {
            switch($opt)
            {
                1 { PORII }
                2 { DXD-BODY }

            }
            # 输出要求的提示
            Write-Host "`nThe function has been called"
            # 暂停等待用户确认后再刷新菜单
            Read-Host -Prompt "`nPress Enter to return to menu"
        }
        else
        {
            Write-Host "`nInvalid option, please enter a number between 1 and 9"
            Read-Host -Prompt "`nPress Enter to try again"
        }
    }
}

1. 新增输入类型转换逻辑，使用[int]::TryParse把输入的字符串转为整数，避免类型不匹配导致的判断失效
2. 修正选项8的调用函数名，和定义的Acronis保持一致
3. 函数执行完成后输出要求的The function has been called提示
4. 新增暂停逻辑，用户按下回车后才会清屏重新加载菜单，可以正常看到执行结果
5. 新增非法输入的提示，优化交互体验
