问题描述

我正在研究一个项目，该项目将使用计算机中的某些文件自动更新USB。

I'm working on a project that will automatically update my USB with some files from my computer.

该程序可在启动时运行，并监视插入计算机的任何USB或CD。我的程序是然后将一些文件夹及其文件复制到USB。我在将文件夹复制到USB时遇到麻烦，谢谢您。

The program works on start up and monitors for any USB or CD that is plugged into the computer. My program is to then copy some folders and its files to the USB. I am having trouble copying the folders into the USB and would appreciate some help, thanks.

推荐答案

此处是可以完成的操作：

private static void DirectoryCopy(string sourceDirName, string destDirName, bool copySubDirs)
{
    DirectoryInfo dir = new DirectoryInfo(sourceDirName);
    DirectoryInfo[] dirs = dir.GetDirectories();

    if (!dir.Exists)
    {
        throw new DirectoryNotFoundException(
            "Source directory does not exist or could not be found: "
            + sourceDirName);
    }

    if (!Directory.Exists(destDirName))
    {
        Directory.CreateDirectory(destDirName);
    }

    FileInfo[] files = dir.GetFiles();
    foreach (FileInfo file in files)
    {
        string temppath = Path.Combine(destDirName, file.Name);
        file.CopyTo(temppath, false);
    }

    if (copySubDirs)
    {
        foreach (DirectoryInfo subdir in dirs)
        {
            string temppath = Path.Combine(destDirName, subdir.Name);
            DirectoryCopy(subdir.FullName, temppath, copySubDirs);
        }
    }
}
