如何在c#中移动保持文件夹结构的文件夹

我正在编写一个C#应用程序，它扫描.jpg图像目录。然后，它更新图像的Exif元信息。一旦完成，它会将新图像保存到一个位置，该位置与获得图像的位置保持相同的文件夹结构。

到目前为止，一切都很好，直到我尝试保存图像，并将其保存在与我获取图像的文件夹相同的文件夹中。

现在的情况是，图像被保存到一个文件夹，而不是多个文件夹。

我获取图像的文件夹结构如下：

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

下面是处理该任务的代码的副本。

/// <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);
        }
    }

有谁能给我指一个正确的方向，或者举一个如何完成这项任务的例子吗。非常感谢您的帮助。谢谢

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，但它给了我错误"与‘System.Image.Drawing.Image.Save（string）’匹配的最佳重载方法有一些无效参数。

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);
        }
    }

上面的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"创建"的定义

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);
                }
            }
