powershell - 方法调用失败 op_addition

Question

在这个脚本中，我从我的 SQL 服务器中提取信息。我创建了 psobject，然后我尝试将每个对象 += 放入 $results 表中，以便我可以获得完整的最终报告。
出于某种原因，如果我一直运行脚本，它会给我错误

Method invocation failed because [system.management.managementobject] does not contain a method named 'op_Addition'

但是，如果我逐行运行脚本，则不会出现错误。

$Results = @()
$servers = get-content .\computers.txt

   # Ping the machine to see if it's on the network
   $results = Get-WMIObject -query "select StatusCode from 
Win32_PingStatus where Address = '$server'" 
   $responds = $false   
   ForEach ($result in $results) {
      # If the machine responds break out of the result loop and indicate success
      if ($result.statuscode -eq 0) {
         $responds = $true
         break
      }
   }
         If ($responds) {

Answer 1

@alroc 有一个有效的观点，那就是很多代码。您可以尝试输入 $Result作为 [array] .

改变

$Results += $object

到

[array]$Results += $object
