获取Dell,Lenovo电脑的保修期

2015-4-6写的代码(Dell), 不知道如何对报错进行友好化处理,于是采用了"非空"和"非空的补集"处理方式.

$service = New-WebServiceProxy -Uri http://143.166.84.118/services/assetservice.asmx?WSDL
$guid = [Guid]::NewGuid()
Import-Csv -Path .sn.csv | foreach {
$info = $service.GetAssetInformation($guid,'diy',$_.sn)
if ($info -ne $null) { 
    $result = $info.Entitlements | foreach {
        $_.EndDate
    } | Measure-Object -Maximum
    $result.Maximum.ToString("yyyy/M/d") | Out-File -FilePath .
esult.csv -Append
    }
else {
    "lenovo" | Out-File -FilePath .
esult.csv -Append #联想电脑暂时不知道如何获取保修期
    } 
}

2015-4-21写的代码(Dell), 含Try, Catch, Finally用法

$service = New-WebServiceProxy -Uri http://143.166.84.118/services/assetservice.asmx?WSDL
$guid = [Guid]::NewGuid()
Import-Csv -Path .sn.csv | foreach {
try {
    $info = $service.GetAssetInformation($guid,'diy',$_.sn)
    $result = $info.Entitlements | foreach { $_.EndDate } | Measure-Object -Maximum
    $result.Maximum.ToShortDateString() | Out-File -FilePath .
esult.csv -Append
}
catch [System.Management.Automation.RuntimeException] {
    "The serail no. is Lenovo!" | Out-File -FilePath .
esult.csv -Append
}
}

2015-5-4写的代码(Lenovo)

Import-Csv -Path .ln.csv | ForEach-Object {
$webreq = Invoke-WebRequest ("http://support1.lenovo.com.cn/lenovo/wsi/usercenter/computersearch/machinesearch.aspx?intcmp=index&id=" + $_.sn + "&showradio=1&showdriver=no")
$gc = $webreq.Content
[regex]::Matches("$gc",'<span id="lblOnSiteEndDate_LK">dddd-dd-dd') | Foreach-object {        #正则表达式
    $_.value.substring($_.value.length - 10, 10)
    }
}

2015-5-4写的代码(Dell & Lenovo)

$lenovo_parttern = "w{10}"
$dell_parttern = "w{7}"
Import-Csv -Path .sn.csv | ForEach-Object {
if(($_.sn -match $dell_parttern) -eq $true) {
    $service = New-WebServiceProxy -Uri http://143.166.84.118/services/assetservice.asmx?WSDL
    $guid = [Guid]::NewGuid()
    $info = $service.GetAssetInformation($guid,'diy',$_.sn)
    $result = $info.Entitlements | foreach { $_.EndDate } | Measure-Object -Maximum
    $result.Maximum.ToShortDateString() | Out-File -FilePath .
esult.csv -Append
}
elseif(($_.sn -match $lenovo_parttern) -eq $true) {
