How to copy all the directories and files in a directory

This article describes how to copy all the files in a directory to the target directory.
Here are a few of the classes that we will use in this routine:
1, Directory:exposes static methods for creating, moving, and enumerating through directories and subdirectories.
2. Path:performs operations on String instances that contain file or directory Path information. These are operations are performed in a cross-platform manner.
3, File:provides static methods for the creation, copying, deletion, moving, and opening of files, and aids in the creation of FileStream objects.
All of these two classes are not inheritable and are inherited directly from object and are implemented as sealed, all of which are explained from MSDN.
Here is the implementation code, the details of the code are not described here in detail, see Code Comments:
// ======================================================
Implement a static method to copy all content under the specified folder to the target folder
// ======================================================
public static void Copydir (String srcpath,string aimpath) {
Checks whether the destination directory ends with a directory split character if it is not added
if (Aimpath[aimpath.length-1]!= Path.directoryseparatorchar)
Aimpath + = Path.directoryseparatorchar;
Determine if the target directory exists if it does not exist the new
if (! Directory.Exists (Aimpath)) directory.createdirectory (Aimpath);
Gets a list of files in the source directory that contains an array of files and directory paths
If you point to the file below the copy destination file and not the directory, use the following method
string[] filelist = Directory.GetFiles (Srcpath);
string[] filelist = directory.getfilesystementries (Srcpath);
Iterate through all the files and directories
foreach (string file in FileList) {
First as a directory processing if there is this directory recursively copy the file below the directory
if (directory.exists (file))
Copydir (file,aimpath+path.getfilename (file));
Otherwise direct copy file
Else
File.Copy (file,aimpath+path.getfilename (file), true);
}
}

Hey! This time to say that the function is relatively simple, suitable for beginners, I hope to help beginners! If you need to use this feature in Web engineering, set sufficient permissions for the ASPNET account, but this is dangerous and is not recommended.
