如何修改要复制的代码和tempDownloadFolder子目录中的文件？

private void moveFiles()
{
   DirectoryInfo di = new DirectoryInfo(tempDownloadFolder);
   FileInfo[] files = di.GetFiles();

   foreach (FileInfo fi in files)
   {
       if (fi.Name != downloadFile)
        File.Copy(tempDownloadFolder + fi.Name, destinationFolder + fi.Name, true);
   }

}

Answer 1

您需要进行递归搜索。

非常粗略的例子：

    private void copyFiles(string filePath)
    {
        DirectoryInfo di = new DirectoryInfo(filePath);
        FileInfo[] files = di.GetFiles();

        foreach (FileInfo fi in files)
        {
            // test if fi is a directory
            // if so call copyFiles(fi.FullName) again
            // else execute the following
            if (fi.Name != downloadFile) File.Copy(filePath+ fi.Name, destinationFolder + fi.Name, true);
        }

    }

Answer 2

如果您想要所有子目录的文件使用SearchOption参数：

DirectoryInfo di = new DirectoryInfo(tempDownloadFolder);
di.GetFiles("*.*", SearchOption.AllDirectories);

FileInfo[] files = di.GetFiles();

foreach (FileInfo fi in files)
{
   if (fi.Name != downloadFile)
   File.Copy(tempDownloadFolder + fi.Name, destinationFolder + fi.Name, true);
}

Answer 3

用

替换File.Copy行

File.Copy(fi.FullName, Path.Combine(destinationFolder, fi.Name), true);
