public static void CopyDirectory(string srcPath, string destPath){ try { DirectoryInfo dir = new DirectoryInfo(srcPath); FileSystemInfo[] fileinfo = dir.GetFileSystemInfos(); //获取目录下(不包含子目录)的文件和子目录 foreach (FileSystemInfo i in fileinfo) { if (i is DirectoryInfo) //判断是否文件夹 { if (!Directory.Exists(destPath+"\\"+i.Name)) { Directory.CreateDirectory(destPath + "\\" + i.Name); //目标目录下不存在此文件夹即创建子文件夹 } CopyDir(i.FullName, destPath + "\\" + i.Name); //递归调用复制子文件夹 } else { File.Copy(i.FullName, destPath + "\\" + i.Name,true); //不是文件夹即复制文件,true表示可以覆盖同名文件 } } } catch (Exception e) { throw; } }
调用CopyDirectory方法前可以先判断原路径与目标路径是否存在
if(Directory.Exists(srcPath)&&Directory.Exists(destPath)){ CopyDirectory(srcPath,destPath); }

调用DelectDir方法前可以先判断文件夹是否存在
if(Directory.Exists(srcPath)){ DelectDir(srcPath);}
