我发现这个 .net 库可以从图像中提取元数据，他们给出的示例如下，但是我输入的任何路径都只是给出了对路径的路径访问被拒绝错误。我以管理员身份运行 Visual Studio，所以这不应该是问题

static void Main(string[] args)
        {

            var directories = MetadataExtractor.ImageMetadataReader.ReadMetadata("C:\\New folder");

            foreach (var directory in directories)
            {
                foreach (var tag in directory.Tags)
                    Console.WriteLine($"[{directory.Name}] {tag.Name} = {tag.Description}");

                if (directory.HasError)
                {
                    foreach (var error in directory.Errors)
                        Console.WriteLine($"ERROR: {error}");
                }
            }

        }

你必须设置文件的路径，而不是文件夹。我试过这样

C:\\New folder\\maxresdefault.jpg
