元数据提取器库路径访问被拒绝

Question

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访问被拒绝的错误。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

而且它的工作原理。输出：

[JPEG] Compression Type = Baseline
[JPEG] Data Precision = 8 bits
[JPEG] Image Height = 720 pixels
[JPEG] Image Width = 1280 pixels
[JPEG] Number of Components = 3
[JPEG] Component 1 = Y component: Quantization table 0, Sampling factors 2 horiz/2 vert
[JPEG] Component 2 = Cb component: Quantization table 1, Sampling factors 1 horiz/1 vert
[JPEG] Component 3 = Cr component: Quantization table 1, Sampling factors 1 horiz/1 vert
[JFIF] Version = 1.1
[JFIF] Resolution Units = inch
[JFIF] X Resolution = 96 dots
[JFIF] Y Resolution = 96 dots
[JFIF] Thumbnail Width Pixels = 0
[JFIF] Thumbnail Height Pixels = 0
[Exif IFD0] X Resolution = 96 dots per inch
[Exif IFD0] Y Resolution = 96 dots per inch
[Exif IFD0] Resolution Unit = Inch
[Exif IFD0] Software = paint.net 4.0.19
[File] File Name = maxresdefault.jpg
[File] File Size = 121177 bytes
