如何在新过程中通过PowerShell WMI创建新的环境更改

Question

我有相同的代码。 通过WMI创建新流程时如何传递新的环境更改（$ ai.EnvironmentVariables =？）
我的示例不起作用，我发出了无效参数（21）

$procClass=[WMICLass]"win32_processstartup"
    $ai = $procClass.createinstance()
    $ai.ShowWindow = 1
    $ai.EnvironmentVariables = @('name', 'testvar')
    $ai.X = 0
    $ai.Y = 0
    $wmiclass = [wmiclass]"win32_process"
    $wmiMethodParameters = $wmiclass.psbase.GetMethodParameters("Create")
    $wmiMethodParameters.CommandLine = "test "
    $wmiMethodParameters.CurrentDirectory = "."
    $wmiMethodParameters.ProcessStartupInformation = $ai
    $pInfoCreate = $wmiclass.psbase.InvokeMethod("Create",$wmiMethodParameters,$null);
    $tempId = $pInfoCreate.ProcessId
    $pInfoObject = get-WmiObject -query "select * from win32_process where processid=$tempId"
