这正在使用所有托管对象，但确实涉及到WMI领域：
private static void Main()
{
foreach (var process in Process.GetProcesses())
{
try
{
Console.WriteLine(process.GetCommandLine());
}
catch (Win32Exception ex) when ((uint)ex.ErrorCode == 0x80004005)
{
// Intentionally empty - no security access to the process.
}
catch (InvalidOperationException)
{
// Intentionally empty - the process exited before getting details.
}
}
}
private static string GetCommandLine(this Process process)
{
using (ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT CommandLine FROM Win32_Process WHERE ProcessId = " + process.Id))
using (ManagementObjectCollection objects = searcher.Get())
{
return objects.Cast<ManagementBaSEObject>().SingleOrDefault()?["CommandLine"]?.ToString();
}
}
