从ObjectReadyEventHandler返回值

Question

我正在编写一个程序，它返回当前登录服务器的用户列表。

这是执行此操作的代码：

private List<string> GetUsers(string server)
    {
        ConnectionOptions options = new ConnectionOptions();
        ManagementScope moScope = new ManagementScope(@"\\" + server + @"\root\cimv2");
        moScope.Connect();
        ObjectQuery query = new ObjectQuery("select * from Win32_Process where name='explorer.exe'");
        ManagementObjectSearcher searcher = new ManagementObjectSearcher(moScope, query);
        ManagementObjectCollection queryCollection = searcher.Get();
        foreach (ManagementObject m in queryCollection)
        {
            ManagementOperationObserver mo = new ManagementOperationObserver();
            mo.ObjectReady += new ObjectReadyEventHandler(mo_ObjectReady);
            m.InvokeMethod(mo, "GetOwner", null);
        }


    }

    private void mo_ObjectReady(object sender, ObjectReadyEventArgs e)
    {
        string user = e.NewObject.Properties["user"].Value.ToString();
        //I would like to return the username back to the GetUsers function. How can I do this?
    }

mo_ObjectReady可以获取当前登录服务器的一个用户名。我怎么能将值返回给GetUsers函数，以便我可以将它们完全放在List中？

提前致谢。
