如何查找通过WMI调用安装的视频Ram的数量？

问题描述：

有谁知道如何从WMI调用中获取PC的视频RAM？如何查找通过WMI调用安装的视频Ram的数量？

我见过对Win32_VideoController管理对象的AdapterRAM属性的调用，但它只给出系统内存，并不代表视频RAM。

原来，这是适配器RAM返回，并通过一个不幸的巧合，使用了错误的转换，并在两个不同的系统上给系统RAM ...。感谢您推动我们再次看。

对于它的价值，在C＃WinForms应用程序：

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); 
    } 
}

从'硬件'下的The Microsoft Technet Script Center Script Repository然后'视频和显示器'，然后'列出视频控制器属性'。

我猜想你可能要AdapterRAM和“VideoMemoryType”

我们已经走下AdapterRAM属性的路径之间制定出一些东西，但是，这只是给我们的系统内存，其中有与Video Ram无关。有没有另一种获得视频内存的方式？

不少集成的芯片组使用系统内存作为显存;你是否在具有真实图形卡或集成显卡的系统上运行测试？ – 2008-12-04 17:12:05

我也这么认为...我们也测试这个代码也在一个集成显卡的MacBook Pro。仍然是相同的行为 – 2008-12-04 18:55:42

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(); 
        }
