C# 3.0 如何获取ram序列号？

我需要知道如何获得RAM物理内存序列号。我使用C和WMI获取硬件信息，但在另一台计算机上序列号返回null。我想知道我怎样才能得到它，并在任何计算机上工作，而不是WMI，如果没有其他方法，我可以用C++编写，并在这个函数与我的应用程序之间进行连接吗？ 这是我的一些代码： WqlObjectQuery Memory3_objectQuery=新的WqlObjectQuerySelect*从Win32_PhysicalMemory； ManagementObjectSearcher Memory3\u Searcher=新建ManagementObjectSearcherMemory3\u objectQuery； foreach management object MO2内存3_search.Get {

这在很大程度上取决于主板制造商。除非在某些服务器板上，否则您将无法获得此信息。要获取所有硬件信息，请访问以下链接，特别链接：
