远程拷贝一个目录下的指定文件。

我现在需要实现的一个功能是把远程IP ：192.168.150.12下的F盘的DATA文件下的所有文件用列表显示出来，然后用户来选择文件，然后上传到本地，这个功能如何实现呢？求解。

解决方案 »

  1.   

    1.获取文件夹及文件夹下的文件
    2.获取选中的文件夹或文件夹下的文件（路径和文件名）
    3.通过路径创建文件夹或将文件下载到指定目录下。
    部分代码参考：
    /// <summary>
            /// 文件备份
            /// </summary>
            public void BackUpImages()
            {           string souce1 = "Resources\\Images";
                if (Directory.Exists(souce1))
                {
                    //filePath.Split(':')[0] + ":\\ImageBackUp\\"
                    string backPath = backupPicPath + DateTime.Now.ToString("yyyyMMddhh") + "images";
                    //获取该目录下的文件夹
                    string[] directoryPaths = Directory.GetDirectories(souce1);                //获取该目录下的文件
                    string[] filepaths = Directory.GetFiles(souce1);
                    CopyFile(filepaths, souce1, backPath);                for (int i = 0; i < directoryPaths.Length; i++)
                    {
                        souce1 = directoryPaths[i];
                        //获取该目录下的文件
                        string[] aFiles = Directory.GetFiles(souce1);
                        CopyFile(aFiles, souce1, backPath);                    //获取该目录下的文件夹
                        string[] directoryPathChild = Directory.GetDirectories(souce1);
                        int indexPath = souce1.LastIndexOf('\\');
                        string fileName = souce1.Remove(0, indexPath + 1);
                        string backPathChild = backPath + "\\" + fileName;
                        //获取该文件夹下是否存在文件夹
                        for (int j = 0; j < directoryPathChild.Length; j++)
                        {
                            souce1 = directoryPathChild[j];
