在 c# 中上传时从图像中删除 Exif 数据的最佳方法是什么

Question

在 C# 中上传时从图像中删除 Exif 数据的最佳方法是什么？我尝试了中给出的解决方案： https://www.techmikael.com/2009/07/removing-exif-data-continued.html

但我面临的问题是，在保存来自上述解决方案的输出流后，图像不可读。它从文件中删除 Exif 信息。但是我稍后无法查看图像。

有人可以帮我吗？

下面是我的代码：

    protected void SaveFile()
    {
        try
        {
            JpegPatcher _jpegPatcher = new JpegPatcher();
            System.IO.Stream stream = new System.IO.MemoryStream();
            //Get stream data of uploaded file
            Stream checkStream = fileUpload.PostedFile.InputStream;
            //Pass the stream to remove Exif info
            Stream outStream1 = _jpegPatcher.PatchAwayExif(checkStream, stream);

            //Save the file
            string Fpath = Path.Combine(path, fileUpload.FileName);
            using (FileStream outputFileStream = new FileStream(Fpath, FileMode.Create, FileAccess.Write))
            {
                stream.Position = 0;
                stream.CopyTo(outputFileStream);
                stream.Flush();
            }

        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

这有帮助和简化吗？请记住，当您开始阅读时，请确保输入流中的位置为 0。

        JpegPatcher _jpegPatcher = new JpegPatcher();
        //Get stream data of uploaded file
        Stream checkStream = fileUpload.PostedFile.InputStream;
        checkStream.Position = 0; // Reset position
        //Pass the stream to remove Exif info
        //Save the file
        string Fpath = Path.Combine(path, fileUpload.FileName);
        using (FileStream outputFileStream = new FileStream(Fpath, FileMode.Create, FileAccess.Write))
        {
            _jpegPatcher.PatchAwayExif(checkStream, outputFileStream);
        }
