[C#]C#最简单方法获取GPU显存真实大小

using System.Management;        

private void getGpuMem()
{
    ManagementClass c = new ManagementClass("Win32_VideoController");
    foreach (ManagementObject o in c.GetInstances())
    {
        string gpuTotalMem = String.Format("{0} ", o["AdapterRam"]);
        Debug.Write(gpuTotalMem);
    }
}

GPGPU gpu = CudafyHost.GetDevice(CudafyModes.Target, CudafyModes.DeviceId);
var c = gpu.GetDeviceProperties(true);
var p = c.TotalMemory;
Console.WriteLine(p);
