问题[weather](computer)

以下 powershell 脚本在有逗号时会输出两次结果。它将字符串分隔为两个条目。我怎样才能让它把它当作一个字符串而不是两个？

Function Get-Weather {
    [Alias('Wttr')]
    [Cmdletbinding()]
    Param(
            [Parameter(
                Mandatory = $true,
                HelpMessage = 'Enter name of the City to get weather report',
                ValueFromPipeline = $true,
                Position = 0
            )]
            [ValidateNotNullOrEmpty()]
            [string[]] $City,
            [switch] $Tomorrow,
            [switch] $DayAfterTomorrow
    )

    Process
    {
        Foreach($Item in $City){
            try {

                # Check Operating System Version
                If((Get-WmiObject win32_operatingsystem).caption -like "*Windows 10*") {
                    $Weather = $(Invoke-WebRequest "http://wttr.in/$City" -UserAgent curl -UseBasicParsing).content -split "`n"
                }
                else {
                    $Weather = (Invoke-WebRequest "http://wttr.in/$City" -UseBasicParsing).ParsedHtml.body.outerText  -split "`n"
                }

                If($Weather)
                {
                    $Weather[0..16]
                    If($Tomorrow){ $Weather[17..26] }
                    If($DayAfterTomorrow){ $Weather[27..36] }
                }
            }
            catch {
                $_.exception.Message
            }
        }            
    }

}
