问题

我正在尝试从笔记本电脑上调用test-Net连接命令，用于超过1000台服务器。我正在使用以下代码进行执行。但是结果总是显示为TRUE，这是不正确的，如果我单独运行命令，那么一些结果也是FALSE。

Test-NetConnection $args[1] -InformationLevel Quiet

$MyObjectArray = Import-Csv ".\Sources.csv";

$AllObjects = @()

for ($i = 0; $i -lt $MyObjectArray.count; $i++)
{
    $SourceServer = $MyObjectArray[$i].Source
    $HostServer = $MyObjectArray[$i].Host
    $PortNumber = $MyObjectArray[$i].Port

    $args = "Test-NetConnection " + $HostServer + " -Port " + $PortNumber

    $result = Invoke-Command -FilePath .\myTNC.ps1 -ArgumentList $args -ComputerName $SourceServer

    $AllObjects += [pscustomobject]@{
        Source = $SourceServer
        Dest = $HostServer
        Port = $PortNumber
        Result = $result
    }
}

$AllObjects | Export-Csv -Path ".\TestResult.csv" -NoTypeInformation

预期输出：
Source, Dest, Port, Result
AAA, BBB, 8080, TRUE
AAA, CCC, 5678, TRUE
BBB, AAA, 7878, FALSE

I am trying to invoke test-Net connection command from laptop for more than 1000 servers. I am using below code for execution. However the result it showing is always TRUE which is not correct , if I ran individual command the several result is FALSE as well. 

Test-NetConnection $args[1] -InformationLevel Quiet

$MyObjectArray = Import-Csv ".\Sources.csv"

Define a new empty Array which will be used to print the data

Invoke-command -ComputerName INDELVR1077 -ScriptBlock {Test-NetConnection INDELVS200 -Port 49667 -InformationLevel Quiet}

   Source = $SourceServer
   Host = $HostServer
   Port = $PortNumber
   Status =$result

}}$AllObjects | Export-Csv -Path ".\TestResult.csv" -NoTypeInformation #Store in CSV file

Expected output:
Source, Dest, Port, Result
AAA,BBB,8080,TRUE
AAA,CCC, 5678, TRUE
BBB,AAA.7878,FALSE

# 答案1
**得分**: 1

$args 被保留，无法使用。通常我会将其命名为 $myargs。严格模式似乎不会捕获它。

```php
$args = 'hi';
$args

# 什么都没有

$myargs = 'hi';
$myargs

hi

$args = 'hi'
$args

# nothing


$myargs = 'hi'
$myargs

hi
