如何读取视频和图片的创建时间

Question

我的目的是选择一个文件夹并读取其中视频和图像的创建时间。我可以对带有位图的图像执行此操作，但在视频上出现错误。这是给您的示例代码。

string[] directoryList = Directory.GetFiles(label1.Text);

        foreach (string file in directoryList) {
            // Create an Image object using the image path
            using (var image = new Bitmap(file))
            {
                // Get the image property items (metadata)
                PropertyItem[] propertyItems = image.PropertyItems;
                string savedDate = null;
                // Iterate over the property items and display the information
                foreach (PropertyItem propertyItem in propertyItems)
                {
                    int type = propertyItem.Type;
                    byte[] value = propertyItem.Value;

                    if (type == 2) // ASCII string
                    {
                        string date = Encoding.ASCII.GetString(value);
                        if (Regex.IsMatch(date, "([0-9]+(:[0-9]+)+)\\s([0-9]+(:[0-9]+)+)") == true)
                        {
                            date = date.Substring(0, 7).Replace(":", "-");
                            savedDate = date;
                            MessageBox.Show(savedDate);
                            break;
                        }



                    }

                    else if (type == 7) // Undefined binary data
                    {
                        // Process the binary data as needed
                        // Example: Console.WriteLine($"Property Value (Binary): {BitConverter.ToString(value)}");
                    }
                }
                //FOLDER CREATING
                if (!Directory.Exists(label1.Text))
                {
                    Directory.CreateDirectory(label1.Text);
                }


            }
        }
