【问题描述】：

我正在尝试在 powershell 中运行以下脚本：

$counters = @()

$counters = $counters + [Diagnostics.CounterCreationData]::("Hit counter", "Number of total hits", [Diagnostics.PerformanceCounterType]::NumberOfItem32);
$counters = $counters + [Diagnostics.CounterCreationData]::("Hits per second", "Number of average hits per second", [Diagnostics.PerformanceCounterType]::RateOfCountsPerSecond32);

$counterCollection = [Diagnostics.CounterCreationDataCollection]::($counters);

[Diagnostics.PerformanceCounterCategory]::Create("HitCounters","Some help text",[Diagnostics.PerformanceCounterCategoryType]::SingleInstance, $counterCollection);

执行此操作时，我收到一条错误消息，提示 $counterCollection 为空。 恐怕我对 powershell 还不够熟悉，无法找出问题出在哪里——是我从中构建集合的数组吗？还是 CounterCreationDataCollection 创建调用本身？

任何指针都非常受欢迎:)

【参考方案1】：

您将静态访问器语法:: 与构造函数调用混合在一起。试试这个：

$ccdTypeName = 'System.Diagnostics.CounterCreationDate'
$ccdcTypeName = 'System.Diagnostics.CounterCreationDataCollection'
$counters = @()
$counters += new-object $ccdTypeName "Hit counter","..."
$counters += new-object $ccdTypeName "Hits per sec","..."
$counterCollection = new-object $ccdcTypeName $counters
...
