下面一段代码给大家介绍C#拷贝整个文件夹以及子目录和其中文件，具体代码如下所示：

private void CopyDirectory( string srcPath, string desPath) { string folderName = srcdir.Substring(srcdir.LastIndexOf( "\\" )+1); string desfolderdir = desPath + "\\" + folderName; if (desdir.LastIndexOf( "\\" ) == (desPath.Length - 1)) { desfolderdir = desPath + folderName; } string [] filenames = Directory.GetFileSystemEntries(srcPath); foreach ( string file in filenames) { if (Directory.Exists(file)) { string currentdir = desfolderdir + "\\" + file.Substring(file.LastIndexOf( "\\" ) + 1); if (!Directory.Exists(currentdir)) { Directory.CreateDirectory(currentdir); } CopyDirectory(file, desfolderdir); } else { string srcfileName = file.Substring(file.LastIndexOf( "\\" )+1); srcfileName = desfolderdir + "\\" + srcfileName; if (!Directory.Exists(desfolderdir)) { Directory.CreateDirectory(desfolderdir); } File.Copy(file, srcfileName); } } }

ps:C# 拷贝指定文件夹下的所有文件及其文件夹到指定目录

要拷贝的文件及其文件夹结构

其中.lab文件不能覆盖

/// <summary>/// 拷贝oldlab的文件到newlab下面/// </summary>/// <param name="sourcePath">lab文件所在目录(@"~\labs\oldlab")</param>/// <param name="savePath">保存的目标目录(@"~\labs\newlab")</param>/// <returns>返回:true-拷贝成功;false:拷贝失败</returns>public bool CopyOldLabFilesToNewLab(string sourcePath, string savePath){ if (!Directory.Exists(savePath)) { Directory.CreateDirectory(savePath); } #region //拷贝labs文件夹到savePath下 try { string[] labDirs = Directory.GetDirectories(sourcePath);//目录 string[] labFiles = Directory.GetFiles(sourcePath);//文件 if (labFiles.Length > 0) { for (int i = 0; i < labFiles.Length; i++) { if (Path.GetExtension(labFiles[i]) != ".lab")//排除.lab文件 { File.Copy(sourcePath + "\\" + Path.GetFileName(labFiles[i]), savePath + "\\" + Path.GetFileName(labFiles[i]), true); } } } if (labDirs.Length > 0) { for (int j = 0; j < labDirs.Length; j++) { Directory.GetDirectories(sourcePath + "\\" + Path.GetFileName(labDirs[j])); //递归调用 CopyOldLabFilesToNewLab(sourcePath + "\\" + Path.GetFileName(labDirs[j]), savePath + "\\" + Path.GetFileName(labDirs[j])); } } } catch (Exception) { return false; } #endregion return true;}
