Question

我正在尝试制作一个备份程序，这是我第一个帮助我学习的小项目之一。

到目前为止，我可以让它复制1个文件，但是当我添加文件列表时，它不会复制。

它的工作方式是我点击添加文件，每个文件路径都添加到我的列表框，然后点击选择目的地，它将目的地添加到变量。

我使用此处的代码复制文件 - Copy the entire contents of a directory in C#

当我向列表框添加1个路径时它会复制好，但是当我添加多个路径时，它基本上将我的2个路径字符串连接在一起并且不起作用。

有没有办法让它逐个复制，或者我是否也将路径添加到数组中，然后从中读取它们？

Answer 1

您要在Event startBtn_Click

中附加每个具有路径字符串的项目

    foreach (var item in listBox1.Items)
    {
        path += item.ToString();
    }

尝试

    foreach (var item in listBox1.Items)
    {
        path = item.ToString();

        //Now Create all of the directories
        foreach (string dirPath in Directory.GetDirectories(path, "*",
           SearchOption.AllDirectories))
           Directory.CreateDirectory(dirPath.Replace(path, backUpDes));

        //Copy all the files & Replaces any files with the same name
        foreach (string newPath in Directory.GetFiles(path, "*.*",
           SearchOption.AllDirectories))
           File.Copy(newPath, newPath.Replace(path, backUpDes), true);

    }

据我所知，这是固定的。

 string path = "";
        for (int i = 0; i < listBox1.Items.Count; i++)
        {
            path = listBox1.Items[i].ToString();
            textBox2.Text += path;

            //Now Create all of the directories
            foreach (string dirPath in Directory.GetDirectories(path, "*",
               SearchOption.AllDirectories))
                Directory.CreateDirectory(dirPath.Replace(path, backUpDes));

            //Copy all the files & Replaces any files with the same name
            foreach (string newPath in Directory.GetFiles(path, "*.*",
               SearchOption.AllDirectories))
                File.Copy(newPath, newPath.Replace(path, backUpDes), true);

            //OLD CODE
            //foreach (var item in listBox1.Items)
            //{
            //    path = item.ToString();

            //    //Now Create all of the directories
            //    foreach (string dirPath in Directory.GetDirectories(path, "*",
            //       SearchOption.AllDirectories))
            //        Directory.CreateDirectory(dirPath.Replace(path, backUpDes));

            //    //Copy all the files & Replaces any files with the same name
            //    foreach (string newPath in Directory.GetFiles(path, "*.*",
            //       SearchOption.AllDirectories))
            //        File.Copy(newPath, newPath.Replace(path, backUpDes), true);
            //}
        }
