Question

伙计们，我有一个问题，也许有人知道答案。我今天与MetadataExtractor一起工作，一切正常，但是有一件事。所有信息都进入了控制台，我不能从那里拿出来... 有谁知道我如何将信息添加到标签？我什至无法访问信息...

 var directories = ImageMetadataReader.ReadMetadata(filename);

        // print out all metadata
        foreach (var directory in directories)
            foreach (var tag in directory.Tags)
                Console.WriteLine($"{directory.Name} - {tag.Name} = {tag.Description}");

        // access the date time
        var subIfdDirectory = directories.OfType<ExifSubIfdDirectory>().FirstOrDefault();
        var dateTime = subIfdDirectory?.GetDateTime(ExifDirectoryBase.TagDateTime);

我这样解决了它（您需要MetadataExtractor软件包）

// access the date time
            var subIfdDirectory = directories.OfType<ExifSubIfdDirectory>().FirstOrDefault();
            var dateTime = subIfdDirectory?.GetDateTime(ExifDirectoryBase.TagDateTime);
            //TEST
            // print out all metadata
            listBox2.Items.Clear();
            foreach (var directory in directories)
            {
                foreach (var tag in directory.Tags)

                    listBox2.Items.Add($"{tag.Description}"); //Import just Information


            }

然后我添加了一个计时器计时器，该计时器将从列表框中获取信息。计时器与进度栏一起使用，以获取信息。

private void timer1_Tick(object sender, EventArgs e)
    {         
        progressBar1.Increment(1);
        if(progressBar1.Value == 1)
        {
            listBox2.SelectedIndex = 20;
            InfoLabel.Text += "      Größe: " + listBox2.SelectedItem.ToString();
        }
        else if (progressBar1.Value == 2)
        {
            listBox2.SelectedIndex = 18;
            InfoLabel.Text += "      Format: " + listBox2.SelectedItem.ToString();
        }
        else if(progressBar1.Value == 3)
        {
            Bitmap img = new Bitmap(listBox1.SelectedItem.ToString());
            var imageHeight = img.Height;
            var imageWidth = img.Width;
            listBox2.SelectedIndex = 3;
            InfoLabel.Text += "      Abmessung: " + img.Width + " x " + img.Height;
        }
        else if (progressBar1.Value == 4)
        {
            listBox2.SelectedIndex = 3;
            InfoLabel.Text += "      Breite: " + listBox2.SelectedItem.ToString();
        }
        else if(progressBar1.Value == 5)
        {
            listBox2.SelectedIndex = 2;
            InfoLabel.Text += "      Höhe: " + listBox2.SelectedItem.ToString();
        }
        else if(progressBar1.Value == 6)
        {
            listBox2.SelectedIndex = 19;
            InfoLabel.Text += "      Dateiname: " + listBox2.SelectedItem.ToString();
        }   
        else
        {
            timer1.Stop();
        }

    }

因为对我来说太难了，所以将所有信息都放在不同的标签中，我只是使用了一个标签，每次都添加了文本。

MetadataExtractor为什么我无法在控制台外部打印我的信息
