备份程序，分离文件路径复制到目标c#

本文关键字：复制 目标 路径 文件 程序 分离 备份 | 更新日期: 2023-09-27 18:11:08

我正在尝试做一个备份程序，这是我第一个帮助我学习的小项目之一。

到目前为止，我可以让它复制一个文件，但是当我添加一个文件列表时，它不复制。

它的工作方式是我点击添加文件，每个文件路径被添加到我的列表框，然后点击选择目的地，它将目的地添加到一个变量。

我正在使用代码从这里复制文件-复制一个目录的整个内容在c#

当我添加一个路径到列表框时，它会正常复制，但当我添加多个路径时，它基本上将我的两个路径字符串连接在一起而不工作。

是否有任何方法可以使它一个接一个地复制，或者我也可以将路径添加到数组中，然后从中读取它们?

备份程序，分离文件路径复制到目标c#

在事件startBtn_Click

中添加每个项目的路径字符串
    foreach (var item in listBox1.Items)
    {
        path += item.ToString();
    }

try with 

    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, "*.*",

            //        File.Copy(newPath, newPath.Replace(path, backUpDes), true);
            //}
        }
