How to Iterate Through a Directory Tree C Programming GuideThe phrase iterate a directory tree means to access each file in each nested subdirectory under a specified root folder, to any depth. You do not necessarily have to open each file. You can just retrieve the name of the file or subdirectory as a string, or you can retrieve additional information in the form of a System. IO. File.

Note In Windows, the terms directory and folder are used interchangeably. Most documentation and user interface text uses the term folder, but the. NET Framework class library uses the term directory. In the simplest case, in which you know for certain that you have access permissions for all directories under a specified root, you can use the System. IO. Search. Option. All. Directories flag. This flag returns all the nested subdirectories that match the specified pattern. The following example shows how to use this flag. Get. Directories., System. IO. Search. Option. All. Directories. The weakness in this approach is that if any one of the subdirectories under the specified root causes a Directory.

This article describes how to upload files through jQuery AJAX in ASP. NET MVC. Not. Found. Exception or Unauthorized. Access. Exception, the whole method fails and returns no directories. The same is true when you use the Get. Files method. If you have to handle these exceptions on specific subfolders, you must manually walk the directory tree, as shown in the following examples. When you manually walk a directory tree, you can handle the subdirectories first pre order traversal, or the files first post order traversal. If you perform a pre order traversal, you walk the whole tree under the current folder before iterating through the files that are directly in that folder itself. The examples later in this document perform post order traversal, but you can easily modify them to perform pre order traversal. Another option is whether to use recursion or a stack based traversal. The examples later in this document show both approaches. If you have to perform a variety of operations on files and folders, you can modularize these examples by refactoring the operation into separate functions that you can invoke by using a single delegate. Note NTFS file systems can contain reparse points in the form of junction points, symbolic links, and hard links. The. NET Framework methods such as Get. Files and Get. Directories will not return any subdirectories under a reparse point. This behavior guards against the risk of entering into an infinite loop when two reparse points refer to each other. In general, you should use extreme caution when you deal with reparse points to ensure that you do not unintentionally modify or delete files. If you require precise control over reparse points, use platform invoke or native code to call the appropriate Win.

In the loop, I will need the filename, and the date at which the file was formatted. Example The following example shows how to walk a directory tree by using recursion. The recursive approach is elegant but has the potential to cause a stack overflow exception if the directory tree is large and deeply nested. The particular exceptions that are handled, and the particular actions that are performed on each file or folder, are provided as examples only. You should modify this code to meet your specific requirements. See the comments in the code for more information. Recursive. File. Search. System. Collections. Specialized. String.
