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: est 转换 为\192.168.0.1D$ est，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 \192.168.0.1D$ est 拷贝到 \192.168.0.2D$ est下 （建议先删除存在文件在拷贝）。
相关code如下：
