Below is a simple example of copying the file (clipping is copying first and then deleting) to the specified path and archived by date in C#. Two points worth noting are:
1) The path of the file is the key, and double slashes are used in the program\\
2) The difference between files and folders
private void DoWork()
{
String dir="D:\\ABC"
//Create backup folder and name it by time String bakDir = dir + "\\bak\\" + ("yyyy-MM-dd");
if ((bakDir) == false){
(bakDir);
}
string[] files = (dir);
if ( != 0) {
foreach (string file in files) {
FileInfo fileinfo = new FileInfo(file);
try{
string fileName = (dir, "");
//Back up files (file,(bakDir,fileName));
(file);
}
}
}
Attached the implementation method of other netizens:
private void CopyDir(string srcPath, string aimPath)
{
try
{
// Check whether the target directory ends with directory segmentation characters. If not, add
if (aimPath[ - 1] != )
{
aimPath += ;
}
// Determine whether the target directory exists or not, create a new one.
if (!(aimPath))
{
(aimPath);
}
// Get the file list of the source directory, which is an array containing the file and directory paths
// If you point to the file below the copy target file without including the directory, please use the following method
// string[] fileList = （srcPath）；
string[] fileList = (srcPath);
// traverse all files and directories
foreach (string file in fileList)
{
// First treat it as a directory. If this directory exists, recursively copy the files below the directory.
if((file))
{
CopyDir(file, aimPath + (file));
}
// Otherwise, directly copy the file
else
{
(file, aimPath + (file),true);
}
}
}
catch(Exception e)
{
throw;
}
}
}
It can be implemented without recursion, and the breadth-first algorithm can save stack space
using System;
using ;
using ;
using ;
string sourcepath=@"C:\sourcedir";
Queue<FileSystemInfo> copyfolders = new Queue<FileSystemInfo>(new DirectoryInfo(sourcepath).GetFileSystemInfos());
string copytopath = @"C:\targetdir";
copytopath = (() == - 1) ? copytopath : (copytopath+) + (sourcepath);
(copytopath);
while (>0)
{
FileSystemInfo atom = ();
FileInfo file = atom as FileInfo;
if (file == null)
{
DirectoryInfo directory = atom as DirectoryInfo;
((sourcepath,copytopath));
foreach (FileSystemInfo fi in ())
(fi);
}
else
((sourcepath,copytopath));
}
