Description
Enumerates the files and directories in a given directory.
Use GetFileSystemEntriesEnumerator to obtain an enumerator object, returning the files and subdirectories in a given directory.
There are two forms of the GetFileSystemEntriesEnumerator method:
- The first form accepts only the path of the directory for which files and subdirectories are enumerated.
- The second form includes a search pattern used when matching subdirectory names.
All the forms also accept an optional TFilterPredicate parameter, used to filter the results.
The following table lists the parameters expected by this method.
| Name | Meaning |
|---|---|
|
Path |
The path of the directory for which subdirectories are enumerated. |
|
SearchPattern |
The mask used when matching directory names (for example, "*app" matches all the files and directories ending with "app"). |
|
Predicate |
A routine used to filter out undesired results. |
Note: GetFileSystemEntriesEnumerator raises an exception if the given path is invalid or the directory does not exist.
