c# 复制文件夹

public static void CopyDirectory(string sourceDirPath,string SaveDirPath)
        {
            try
            {
                //如果指定的存储路径不存在，则创建该存储路径
                if (!Directory.Exists(SaveDirPath))
                {
                    //创建
                    Directory.CreateDirectory(SaveDirPath);
                }
                //获取源路径文件的名称
                string[] files = Directory.GetFiles(sourceDirPath);
                //遍历子文件夹的所有文件
                foreach(string file in files)
                {
                    string pFilePath = SaveDirPath + "\\" + Path.GetFileName(file);
                    if (File.Exists(pFilePath))
                        continue;
                    File.Copy(file, pFilePath, true);
                }
                string[] dirs = Directory.GetDirectories(sourceDirPath);
                //递归，遍历文件夹
                foreach (string dir in dirs)
                {
                    CopyDirectory(dir, SaveDirPath + "\\" + Path.GetFileName(dir));
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }

第二种

static void CopyFolder(string srcPath, string desPath)
        {

            string strFolderName = srcPath.Substring(srcPath.LastIndexOf("\\") + 1, srcPath.Length - srcPath.LastIndexOf("\\") - 1);
            //获得文件名夹名
            if (!Directory.Exists(desPath + "\\" + strFolderName))
                Directory.CreateDirectory(desPath + "\\" + strFolderName);//目标文件夹没此文件夹，则创建
            string[] strFiles = Directory.GetFiles(srcPath, "", SearchOption.AllDirectories);//获得文件夹所有文件
            foreach (string strFilesElement in strFiles)
            {
                var strFileName = strFilesElement.Substring(strFilesElement.LastIndexOf("\\") + 1, strFilesElement.Length - strFilesElement.LastIndexOf("\\") - 1);
                //获得文件名
                string tarAddress = desPath + "\\" + strFileName;//目标路径
                File.Copy(strFilesElement, tarAddress, true);//复制
            }
            DirectoryInfo dirInfo = new DirectoryInfo(srcPath);//获得其他文件，对每个文件夹做递归操作
            DirectoryInfo[] dirPath = dirInfo.GetDirectories();
            foreach (var dirPathElement in dirPath)
            {
                CopyFolder(srcPath + "\\" + dirPathElement.Name, desPath + "\\" + dirPathElement.Name);
            }

        }
