如果你需要在 C# 中检测是否安装了支持 CUDA 的 GPU，可以使用 ManagedCuda 库。下面是一个简单的方法来检查 CUDA 设备的存在。

1.安装 ManagedCuda 库

2.检测 CUDA GPU

using System;
using ManagedCuda;public static bool HasCudaGPU()
{try{// 获取 CUDA 设备数量int deviceCount = CudaContext.GetDeviceCount();if (deviceCount > 0){Console.WriteLine($"CUDA GPU detected: {deviceCount} device(s)");for (int i = 0; i < deviceCount; i++){// 获取设备属性var deviceProperties = CudaContext.GetDeviceInfo(i);Console.WriteLine($"Device {i}: {deviceProperties.DeviceName}");Console.WriteLine($"  Compute Capability: {deviceProperties.ComputeCapability.Major}.{deviceProperties.ComputeCapability.Minor}");Console.WriteLine($"  Total Memory: {deviceProperties.TotalGlobalMemory / 1024 / 1024} MB");}return true; // 检测到 CUDA GPU}else{Console.WriteLine("No CUDA-enabled GPU detected.");return false;}}catch (CudaException ex){// 捕获特定的 CUDA 异常并处理Console.WriteLine("CUDA error: " + ex.Message);}catch (Exception ex){Console.WriteLine("Error detecting CUDA GPU: " + ex.Message);}return false;
}
