C# 備份、還原、拷貝遠程文件夾


最近一直都很忙,非常抱歉好久沒有寫過博客了。最近遇到拷貝遠程文件的一些工作,比如我們發布的web站點的時候,開發提供一個zip壓縮包,我們需要上傳到遠程的服務器A,然后在部署(文件拷貝)到遠程環境B和C,ABC都在一個局域網里面。文件壓縮需要引用 System.IO.Compression和System.IO.Compression.FileSystem

首先我們需要一個工具類來轉換文件路徑,本地地址與遠程地址的轉換 比如192.168.0.1上的D:\test 轉換 為\\192.168.0.1\D$\test,文件路徑的拼接,

 public class PathUtil
    {
        public static string GetRemotePath(string ip, string localPath)
        {
            if (!localPath.Contains(":"))
            {
                throw new Exception($"{localPath}路徑必須是全路徑且是本地路徑");
            }
            localPath = localPath.Replace(":", "$");
            return $@"\\{ip}\{localPath}";
        }

        public static string GetLocaPath(string remotePath)
        {
            int index = remotePath.IndexOf("$");
            if (index < 1)
            {
                throw new Exception($"{remotePath}路徑必須包含磁盤信息");
            }

            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;
        }
    }

備份遠程目錄的文件夾 (首先備份遠程A目錄到本地臨時文件zip->拷貝到遠程B->刪除本地臨時文件zip

還原遠程文件(部署發布包)(遠程文件解壓到本地臨時目錄->拷貝到目標服務器->刪除本地臨時目錄

文件夾得拷貝就比較簡單,遞歸調用文件復制就okay了,比如 \\192.168.0.1\D$\test 拷貝到  \\192.168.0.2\D$\test下 (建議先刪除存在文件在拷貝)

相關code如下:

  #region 文件操作部分
        /// <summary>
        /// 把一個目錄下的文件拷貝的目標目錄下
        /// </summary>
        /// <param name="sourceFolder">源目錄</param>
        /// <param name="targerFolder">目標目錄</param>
        /// <param name="removePrefix">移除文件名部分路徑</param>
        public void CopyFiles(string sourceFolder, string targerFolder, string removePrefix = "")
        {
            if (string.IsNullOrEmpty(removePrefix))
            {
                removePrefix = sourceFolder;
            }
            if (!Directory.Exists(targerFolder))
            {
                Directory.CreateDirectory(targerFolder);
            }
            DirectoryInfo directory = new DirectoryInfo(sourceFolder);
            //獲取目錄下的文件
            FileInfo[] files = directory.GetFiles();
            foreach (FileInfo item in files)
            {
                if (item.Name == "Thumbs.db")
                {
                    continue;
                }
                string tempPath = item.FullName.Replace(removePrefix, string.Empty);
                tempPath = targerFolder + tempPath;
                FileInfo fileInfo = new FileInfo(tempPath);
                if (!fileInfo.Directory.Exists)
                {
                    fileInfo.Directory.Create();
                }
                File.Delete(tempPath);
                item.CopyTo(tempPath, true);
            }
            //獲取目錄下的子目錄
            DirectoryInfo[] directors = directory.GetDirectories();
