创建子文件夹

Question

我在转换时遇到了一些问题，我尝试转换有子文件夹的文件夹，但它没有创建子文件夹，只创建一个文件夹“_converted”，文件夹中是所有转换后的子文件夹图像。

我的代码：

private void btnConvert_Click(object sender, EventArgs e)
{
    string[] originalImage = Directory.GetDirectories(txtFilePath.Text, "*.*", 
                                                            SearchOption.AllDirectories);
    foreach (var directory in originalImage)
    {
        Debug.WriteLine(directory);
    }
    foreach (string dir in originalImage)
    {

        string folderPath = @"C:\test\" + "_converted";
        folderPath = folderPath.Substring(folderPath.IndexOf(@"\") + 1);
        DirectoryInfo di = Directory.CreateDirectory(folderPath);
        if (Directory.Exists(folderPath))
        {
            DirectoryInfo dInfo = new DirectoryInfo(dir);
            foreach (var filename in dInfo.GetFiles())
            {

                FileInfo fInfo = new FileInfo(filename.FullName);
                var fileExtension = fInfo.Extension;
                var fileOriginalDate = fInfo.CreationTime;

                if (fileExtension.ToUpper() == ".JPG" || fileExtension.ToUpper() == ".PNG")
                {
                    using (Bitmap bitmap = new Bitmap(filename.FullName))
                    {
                        string fn = Path.GetFileNameWithoutExtension(filename.FullName);
                        VariousQuality(bitmap, fn, fileExtension, 
                                              fileOriginalDate, folderPath);
                    }
                }
            }
        }
    }
}

我试过用这个方法：

folderPath = folderPath.Substring(folderPath.IndexOf(@"\") + 1);

我该如何解决这个问题？

Answer 1

您在循环的每次迭代中都创建了相同的文件夹。只需通过替换以下行来使用当前目录创建一个文件夹：

string folderPath = @"C:\test\" + "_converted";
folderPath = folderPath.Substring(folderPath.IndexOf(@"\") + 1);

这一行：

string folderPath = Path.Combine(@"C:\test\", dir + "_converted");

Answer 2

您没有正确处理文件夹的名称。试试这个：

private void btnConvert_Click(object sender, EventArgs e)
{
    string[] originalImage = Directory.GetDirectories(txtFilePath.Text, "*.*", SearchOption.AllDirectories);

    foreach (var directory in originalImage)
    {
        Debug.WriteLine(directory);
    }
    foreach (string dir in originalImage)
    {
        // The name of the current folder (dir)
        // This will convert "C:\Users\User\Desktop\Myfolder\Image1" to simply "Image1" since we create a substring after the LAST backslash ('\')
        string folderName = dir.Substring(dir.LastIndexOf('\') + 1); // Ex. "Image1"

        // This will now be "C:\test\FOLDERNAME_converted"
        string folderPath = @"C:\test\" + folderName + @"_converted\"; // Ex. "C:\test\image1_converted\";

        // This can now create the folders
        DirectoryInfo di = Directory.CreateDirectory(folderPath);

        // Below is unchanged for now
        if (Directory.Exists(folderPath))
        {
            DirectoryInfo dInfo = new DirectoryInfo(dir);
            foreach (var filename in dInfo.GetFiles())
            {
                FileInfo fInfo = new FileInfo(filename.FullName);
                var fileExtension = fInfo.Extension;
                var fileOriginalDate = fInfo.CreationTime;

                if (fileExtension.ToUpper() == ".JPG" || fileExtension.ToUpper() == ".PNG")
                {
                    using (Bitmap bitmap = new Bitmap(filename.FullName))
                    {
                        string fn = Path.GetFileNameWithoutExtension(filename.FullName);
                        VariousQuality(bitmap, fn, fileExtension,
                                              fileOriginalDate, folderPath);
                    }
                }
            }
        }
    }
}

希望对您有所帮助。

我只有一个问题。在您的目录路径 (txtFilePath.Text) 中获取目录时，您会获取所有文件夹，包括子文件夹 (SearchOptions.AllDirectories)。将转换后的文件夹保存到“C:\test”文件夹时，您没有考虑到文件夹可能是子文件夹。因此，会出现以下问题。假设您有一个文件夹和一个文件夹：

"HeadFolder -> Image1 -> Image1.2"

程序将找到的内容：

1. "Path\To\Image1"
2. "Path\To\Image1.2"

转换后您将获得：

"HeadFolder"
    "Image1"
    "Image1.2"

请注意，"Image1.2" 并未像转换前那样在 "Image1" 内结束
