C# 备份、还原、拷贝远程文件夹

最近一直都很忙，非常抱歉好久没有写过博客了。最近遇到拷贝远程文件的一些工作，比如我们发布的web站点的时候，开发提供一个zip压缩包，我们需要上传到远程的服务器A，然后在部署（文件拷贝）到远程环境B和C，ABC都在一个局域网里面。文件压缩需要引用 System.IO.Compression和System.IO.Compression.FileSystem

首先我们需要一个工具类来转换文件路径，本地地址与远程地址的转换 比如192.168.0.1上的D:\test 转换 为\\192.168.0.1\D$\test，文件路径的拼接，

 public class PathUtil    {        public static string GetRemotePath(string ip, string localPath)        {            if (!localPath.Contains(":"))            {                throw new Exception($"{localPath}路径必须是全路径且是本地路径");            }            localPath = localPath.Replace(":", "$");            return $@"\\{ip}\{localPath}";        }        public static string GetLocaPath(string remotePath)        {            int index = remotePath.IndexOf("$");            if (index < 1)            {                throw new Exception($"{remotePath}路径必须包含磁盘信息");            }            string temp = remotePath.Substring(index - 1);            temp = temp.Replace("$", ":");            return temp;        }        public static string Combine(string path1, string path2)        {            path1 = path1.Trim();            path2 = path2.Trim();            if (path1.EndsWith("\\") && path2.StartsWith("\\"))            {                string ret = (path1 + path2).Replace("\\", "");                return ret;            }            else if (!path1.EndsWith("\\") && !path2.StartsWith("\\"))            {                return path1 + "\\" + path2;            }            // if ((path1.EndsWith("\\") && !path2.StartsWith("\\")) ||            //(!path1.EndsWith("\\") && path2.StartsWith("\\"))) { }            return path1 + path2;        }    }

备份远程目录的文件夹 （首先备份远程A目录到本地临时文件zip->拷贝到远程B->删除本地临时文件zip）

还原远程文件（部署发布包）（远程文件解压到本地临时目录->拷贝到目标服务器->删除本地临时目录）

文件夹得拷贝就比较简单，递归调用文件复制就okay了，比如 \\192.168.0.1\D$\test 拷贝到  \\192.168.0.2\D$\test下 （建议先删除存在文件在拷贝）。

相关code如下：
