如何通过 WMI 调用找到安装的视频 RAM 数量？

Question

有谁知道如何从 WMI 调用中获取 PC 的视频 RAM？

我见过对 Win32_VideoController 管理对象的 AdapterRAM 属性的调用，但这仅提供系统内存，根本不代表视频 RAM。

Answer 1

结果是适配器 RAM 返回，并且由于不幸的巧合，使用了错误的转换并在两个不同的系统上提供了系统 RAM。 感谢您推动我们再次查看。

就其价值而言，在 C# WinForms 应用程序中：

int _ram = 0;

ManagementObjectSearcher searcher = new ManagementObjectSearcher("select AdapterRAM from Win32_VideoController");

foreach (ManagementObject mo in searcher.Get())
{
   var ram = mo.Properties["AdapterRAM"].Value as UInt32?;

   if (ram.HasValue)
   {
      _ram = ((int)ram/1048576);
   }
}

Answer 2

来自“硬件”下的 Microsoft Technet 脚本中心脚本存储库，然后是“视频和显示” '然后'列出视频控制器属性'。

我想你可能需要在 AdapterRAM 和“VideoMemoryType”之间解决一些问题

我们已经沿着 AdapterRAM 属性的路径走了下去，但这只是为我们提供了系统内存，与视频 RAM 无关。 还有其他方法获得视频内存吗？

Answer 4

ManagementObjectSearcher searcher = new ManagementObjectSearcher("select AdapterRAM from 

    Win32_VideoController");

                    foreach (ManagementObject mo in searcher.Get())
                    {                            

                        double MemorySize = Convert.ToDouble(mo.Properties["AdapterRAM"].Value) / 1048576;

                        return MemorySize.ToString();
                    }
