# Chilkat SFtpDir — C# — v11.7.0

> Chilkat 11.7.0 · language=csharp · class=SFtpDir
> Other versions: replace `11.7.0` in this URL. Other languages: `https://www.chilkatsoft.com/ai-docs/v/11.7.0/<lang>/classes/SFtpDir.md`.
> Language-wide rules (install, unlock, error model, strings/bytes): `https://www.chilkatsoft.com/ai-docs/v/11.7.0/csharp/guide.md`.

## Purpose

**Inspect, sort, and iterate an SFTP directory listing.**

`Chilkat.SFtpDir` represents a directory listing returned by an SFTP operation. It provides the original path used to fetch the listing, the number of files and subdirectories found, methods for retrieving filenames or full `SFtpFile` entry details by index, sorting support, and a way to load a completed asynchronous directory-listing result.

**Directory listing object**

Holds the files and subdirectories returned from an SFTP directory-read operation.

**Original path tracking**

Use `OriginalPath` to see the remote path that was requested when the directory listing was created.

**Entry count**

Read `NumFilesAndDirs` to determine how many directory entries are available for iteration.

**Filename access**

Use `GetFilename` to retrieve the name of an entry by zero-based index.

**Full entry details**

Use `FileAt` to populate an `SFtpFile` object with metadata for a selected file or subdirectory.

**Sorting and async results**

Sort entries by filename, timestamps, or size, and load directory listings returned from completed async tasks.

**Common pattern:** Use a `Chilkat.SFtp` object to open or read a remote directory, then use the returned `SFtpDir` object to inspect `NumFilesAndDirs`, optionally call `Sort`, and loop from index `0` through the final entry. Use `GetFilename` when only names are needed, or `FileAt` when the application needs the full `SFtpFile` metadata for each entry.

## Object creation, unlocking and error handling

**Object Creation**

```csharp
Chilkat.SFtpDir obj = new Chilkat.SFtpDir();
```

Call `Global.UnlockBundle` once at the start of the program, before using this or any other Chilkat class. Any string unlocks a fully functional 30-day trial; a purchased unlock code is used in production. See `guide.md` for the exact code in C#.

Minimal complete program:

```csharp
// Required once per process. Any string unlocks a 30-day trial; use your purchased code in production.
Chilkat.Global glob = new Chilkat.Global();
if (!glob.UnlockBundle("Anything for 30-day trial"))
{
    Console.WriteLine(glob.LastErrorText);
    return;
}

Chilkat.SFtpDir sFtpDir = new Chilkat.SFtpDir();
```

How failure is reported depends on the method's return type and is stated in the note under each method below. In every case the diagnostic text is in the `LastErrorText` property of the object whose method was called.

## Members common to every Chilkat class

Documented once per language in `common-members.md`; listed here so this page is self-contained.

| Property | Signature | Access | Meaning |
|---|---|---|---|
| `DebugLogFilePath` | `public string DebugLogFilePath {get; set; }` | read/write | If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. |
| `LastErrorHtml` | `public string LastErrorHtml {get; }` | read-only | Provides HTML-formatted information about the last called method or property. |
| `LastErrorText` | `public string LastErrorText {get; }` | read-only | Provides plain text information about the last called method or property. |
| `LastErrorXml` | `public string LastErrorXml {get; }` | read-only | Provides XML-formatted information about the last called method or property. |
| `LastMethodSuccess` | `public bool LastMethodSuccess {get; set; }` | read/write | Indicates the success or failure of the most recent method call: `true` means success, `false` means failure. |
| `VerboseLogging` | `public bool VerboseLogging {get; set; }` | read/write | If set to `true`, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. |
| `Version` | `public string Version {get; }` | read-only | Version of the component/library, such as "10.1.0" |

## Member index

| Member | Kind | Signature |
|---|---|---|

| `FileAt` | method | `public bool FileAt(int index, SFtpFile fileObj);` |
| `GetFilename` | method | `public string GetFilename(int index);` |
| `LoadTaskResult` | method | `public bool LoadTaskResult(Task task);` |
| `Sort` | method | `public void Sort(string field, bool ascending);` |

Deprecated members are listed at the end of this file with their replacements; do not use them in new code.

## Properties

### SFtpDir.NumFilesAndDirs

`Chilkat 11.7.0 · csharp · SFtpDir · NumFilesAndDirs · property · read-only`

```csharp
public int NumFilesAndDirs {get; }
```

Returns the number of entries in this directory listing.

The count includes every item returned by the server, such as regular files, directories, symbolic links, and special entries. Valid zero-based indexes range from `0` through `NumFilesAndDirs - 1`.

### SFtpDir.OriginalPath

`Chilkat 11.7.0 · csharp · SFtpDir · OriginalPath · property · read-only`

```csharp
public string OriginalPath {get; }
```

Returns the original remote path used to create this directory listing.

This is the same path string that was supplied to the SFTP directory-open operation. It identifies the requested directory and is retained with the listing for later reference.

## Methods

### SFtpDir.FileAt

`Chilkat 11.7.0 · csharp · SFtpDir · FileAt · method · since 11.0.0`

```csharp
public bool FileAt(int index, SFtpFile fileObj);
```

Copies the metadata for the directory entry at the zero-based `index` into `fileObj`.

The first entry is at index `0`. Use `NumFilesAndDirs` to determine the number of available entries.

The populated `SFtpFile` object provides the entry name, type, size, timestamps, ownership, permissions, and any additional attributes supplied by the SFTP server.

Use `GetFilename` when only the entry name is needed.

Returns true for success, false for failure.

### SFtpDir.GetFilename

`Chilkat 11.7.0 · csharp · SFtpDir · GetFilename · method`

```csharp
public string GetFilename(int index);
```

Returns the filename of the directory entry at the zero-based `index`.

The first entry is at index `0`. Use `NumFilesAndDirs` to determine the number of available entries.

Use `FileAt` when the application needs the full `SFtpFile` metadata rather than only the entry name.

Returns `null` on failure

### SFtpDir.LoadTaskResult

`Chilkat 11.7.0 · csharp · SFtpDir · LoadTaskResult · method · since 9.5.0.52`

```csharp
public bool LoadTaskResult(Task task);
```

Loads this `SFtpDir` object from the result of a completed asynchronous `Task`.

The task must represent an asynchronous SFTP operation whose result is a directory listing. Call this method after the task has finished to transfer the listing data into the current object.

Returns true for success, false for failure.

### SFtpDir.Sort

`Chilkat 11.7.0 · csharp · SFtpDir · Sort · method · since 9.5.0.79`

```csharp
public void Sort(string field, bool ascending);
```

Reorders the files and subdirectories in this listing according to `field`.

Set `ascending` to `true` for ascending order or `false` for descending order. The new order is used by index-based methods such as `GetFilename` and `FileAt`.

| field | Sort key |
| :--- | :--- |
| `filename` | Filename using the normal case-sensitive comparison. |
| `filenameNoCase` | Filename using a case-insensitive comparison. |
| `lastModifiedTime` | Last-modified date and time. |
| `lastAccessTime` | Last-access date and time. |
| `lastCreateTime` | Creation date and time. |
| `size` | Entry size in bytes. |

## Deprecated members — do not use in new code

| Member | Kind | Deprecated in | Use instead |
|---|---|---|---|
| `GetFileObject` | method | before 11.6.1 | `FileAt` |
