Question

我正在编写一个C＃应用程序，它扫描.jpg图像的目录。然后它更新图像的Exif元信息。完成此操作后，它会将新图像保存到保持与获取图像的文件夹结构相同的位置。

到目前为止，一切正常，直到我尝试保存图像，并保存与我从中获取图像的文件夹相同的文件夹。

正在发生的事情是图像被保存到单个文件夹而不是多个文件夹。

我获取图像的文件夹结构如下所示：

1997 -> JAN-JUN 1997 -> APRIL 1997 -> 7.4.97 - 11.4.97 -> FRI 11.4.97

以下是处理任务的代码的副本。

/// <summary>
    /// Search the directories
    /// </summary>
    /// <param name="sDir">Pass in the directory to be searched</param>
    void DirSearch(string sDir)
    {
        try
        {
            foreach (string d in Directory.GetDirectories(sDir))
            {
                foreach (string f in Directory.GetFiles(d, txtfile.Text))
                {
                    if (progressBar1.Value < progressBar1.Maximum)
                    {

                        // Return the folder name - only the data part e.g 7.9.1997
                        string folderName = new FileInfo(f).Directory.Name;
                        string[] parts = folderName.Split(' ');
                        string lastPart = parts[parts.Length - 1];

                        // minimally loads image and closes it
                        ExifPropertyCollection properties = ExifReader.GetExifData(f.ToString());

                        int lastDot = imagePath.LastIndexOf('.');

                        string inputPath = f.ToString();
                        string outputPath = destinationDir + getFileNameFromPathString(f.ToString()) + ".jpg";

                        // add copyright tag
                        ExifProperty copyright = new ExifProperty();
                        copyright.Tag = ExifTag.Copyright;
                        copyright.Value = String.Format(
                                "Copyright (c){0} Shepparton News. All rights reserved.",
                                DateTime.Now.Year);

                        // Add folder date to exif tag
                        ExifProperty folderDate = new ExifProperty();
                        folderDate.Tag = ExifTag.DateTime;
                        folderDate.Value = lastPart.ToString();

                        ExifWriter.AddExifData(inputPath, outputPath, copyright, folderDate);


                        ListViewItem item = lstFilesFound.Items.Add(getFileNameFromPathString(f.ToString()));
                        item.SubItems.Add(lastPart.ToString());
                        item.SubItems.Add(f.ToString());

                        progressBar1.PerformStep();
                    }
                }
                DirSearch(d);
            }

        }
        catch (System.Exception ex)
        {
            Console.WriteLine(ex.Message);
        }
    }

有人可以指出我正确的方向或提供一个如何实现这一任务的例子。任何帮助非常感谢。感谢。

以下是一些辅助方法：

/// <summary>
    /// Return the name of a file
    /// </summary>
    /// <param name="filePathString">The filepathstring to search</param>
    public static string getFileNameFromPathString(string filePathString)
    {
        filePathString = filePathString.Replace("\\", "/");
        string[] pathParts = Regex.Split(filePathString, "/");
        return pathParts[pathParts.Length - 1];
    }

图像保存方法：

public static void AddExifData(string inputPath, string outputPath, params ExifProperty[] properties)
    {
        using (Image image = Image.FromFile(inputPath))
        {
            ExifWriter.AddExifData(image, new ExifPropertyCollection(properties));
            image.Save(outputPath);
        }
    }

这是我尝试使用的新方法，但是它给了我错误“'System.Image.Drawing.Image.Save（string）'的最佳重载方法匹配'有一些无效的参数。

public static void AddExifData(string inputPath, DirectoryInfo outputPath, params ExifProperty[] properties)
    {
        if (!outputPath.Exists)
        {
            outputPath.Create();
        }

        using (Image image = Image.FromFile(inputPath))
        {
            ExifWriter.AddExifData(image, new ExifPropertyCollection(properties));
            image.Save(outputPath);
        }
    }

新的AddExifData方法

public static void AddExifData(string inputPath, string outputPath, params ExifProperty[] properties)
    {
        if (!Directory.Exist(outputPath)) { Directory.Create(outputPath); }

        using (Image image = Image.FromFile(inputPath))
        {
            ExifWriter.AddExifData(image, new ExifPropertyCollection(properties));

            image.Save(outputPath.ToString(), ImageFormat.Jpeg);
        }
    }

上面这个新方法给了我这些错误。 System.IO.Directory不包含“Exist”的定义 System.IO.Directory不包含“Create”

的定义

最后：

void DirSearch(string sDir, string relativeDir)
            {

                foreach (string f in Directory.GetFiles(sDir,txtfile.Text))
                    {
                        //doing something...

                        string outputPath = destinationDir + relativeDir + getFileNameFromPathString(f.ToString()) + ".jpg";

                        //doing more...

                    }
                foreach (string d in Directory.GetDirectories(sDir))
                {

                     int lst = d.LastIndexOf("\\") + 1;
                    string newRelative = relativeDir + d.Substring(lst, d.Length - lst) + "\\";
                    //relativeDir = relativeDir + d.Substring(lst, d.Length - lst) + "\\";
                    DirSearch(d, newRelative);
                }
            }
