我刚刚试了下，我选择一张照片以后多点几次对比，服务一样会蹦掉呢

你好，我又测试了以下，刚刚的例子在频繁点击上传的时候确实会出现问题。
然后以下是改进(刚刚测试没有问题了)。可以参考一下：

[Route("api/[controller]/[action]")]
[ApiController]
public class ViewFaceController : ControllerBase
{
    private readonly static object locker = new object();

    private static ViewFace viewFace;

    static ViewFaceController()
    {
        string modelPath = Path.Combine(AppContext.BaseDirectory, @"model/");
        viewFace = new ViewFace(modelPath);
        GC.SuppressFinalize(viewFace);
    }

    [HttpPost]
    public IActionResult UploadSmallFile(IFormFile file)
    {
        if (file == null)
        {
            return new Result("未接收到上传的文件", -1001);
        }
        
        lock (locker)
        {
            using MemoryStream ms = new MemoryStream();
            file.CopyTo(ms);
            using Bitmap bitmap = new Bitmap(ms);
            var res = viewFace.FaceDetector(bitmap);
            var message = res.Length > 0 ? "人脸识别成功" : "未检测到人脸";
            return new Result<FaceInfo[]>(res, message);
        }
    }
}
