我有一个项目需要从带有图形卡的计算机中收集信息，从1到12，它有。然后将此信息保存在云中以供以后使用。
我需要的是，对于最小化是：
它是什么GPU 记忆多少钱 它正在使用哪个PCI插槽，1,2,3等（或任何名称）
Windows WMI似乎有一些信息，我一直在查看不同的类，但似乎很难找到PCI-E插槽。有谁知道如何获取这些信息？答案 0 :(得分：1)
你应该寻找 PCI 插槽我没有在字符串中看到任何 PCI-E 定义（并不意味着没有）。如果我只尝试"PCI"，则结果会同时包含 PCI 和 PCI-E 设备。在 BDS2006 C ++ / VCL 中我只是通过更改匹配字符串来使用this（我之前已经破坏了）：

忽略 VCL 的内容。重要的是USBinfo()功能（是的，我用它来获取 USB 信息）。它将枚举所有设备（如在设备管理器中）匹配您启动它的字符串（其中3个类似的第2行补救）。请注意AnsiString是字符串类（元素是从[1]而不是[0]访问的）而DWORD是无符号的32位int。 Main->mm_log只是TMemo，我输出结果。不要忘记包含setupapi.h

然而，当您收集GPU信息时，您可能还想尝试使用OpenGL方法：
您可以收集支持的扩展和功能列表，还可以获得特定的GPU信息，例如管道数量，纹理单元，甚至是一些免费的内存......
