第一个短代码,然后问题

$session = New-PSSession -ComputerName someServer

$servicesList = "Service1", "Service2", "Service3"

Invoke-Command -ScriptBlock {
    Param ($newServicesList)

    Write-Host $newServicesList

} -ArgumentList $servicesList -Session $session

Remove-PSSession  $session

问题是为什么Invoke-Command块中的Write-Host只给出这个输出？

Service1

谢谢你的回答

I have a question about delegate in this code, I add three method to delegate. There're return a string. In the line

string delOut = del("Beer");

to my valuable delOut delegate assignet this "Length : 4"

How can I collect all strings that methods in delegate returns ?

public class NaForum
{
    public delegate string MyDelegate(string s);

    public void TestDel()
    {
        MyDelegate del = s => s.ToLower();
        del += s => s.ToUpper();
        del += s => string.Format("Length : {0}", s.Length); …

我从NewWebServiceProxy cmdlet捕获异常时遇到问题

try {
    $myService = New-WebServiceProxy -Uri "http://localhost/someservice.svc"
}
catch {
    Write-Log ([string]::Format("Error : {0}", $_.Exception.Message))
}

当我运行它时,我得到了这个未处理的异常:New-WebServiceProxy:

请求失败,HTTP状态为404:未找到.在C:\ Users\SomeUser\AppData\Local\Temp\d052b604-38ad-4827-b952-4ebc66e79c69.ps1:2 char:18 + $ myService = New-WebServiceProxy -Uri "http://localhost/someservice.svc" + ~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ CategoryInfo:ObjectNotFound :( http://localhost/someservice.svc:Uri)[New-WebServiceProxy],WebExc eption + FullyQualifiedErrorId:WebException,Microsoft.PowerShell.Commands.NewWebServiceProxy

有人可能会问我为什么尝试捕获不捕获此异常？谢谢你的任何aswer
