Return Value

Type: System.Collections.Generic::IEnumerable<FileSystemInfo^>^

An enumerable collection of file system information in the current directory.

DirectoryNotFoundException

SecurityException

The caller does not have the required permission.

The EnumerateFileSystemInfos and GetFileSystemInfos methods differ as follows:

  • When you use EnumerateFileSystemInfos, you can start enumerating the collection of FileInfo objects before the whole collection is returned.

  • When you use GetFileSystemInfos, you must wait for the whole array of FileSystemInfo objects to be returned before you can access the array.

Therefore, when you are working with many files and directories, EnumerateFileSystemInfos can be more efficient.

This method pre-populates the values of the following FileSystemInfo properties:

The returned collection is not cached; each call to the GetEnumerator method on the collection will start a new enumeration.
