Ftp.FileExistsAsync Method

Namespace: Rebex.Net

Assembly: Rebex.Ftp.dll (version 7.0.9147)

FileExistsAsync(String, Object)

Begins asynchronous FileExists operation. Detects whether the specified file exists on the server. Not all FTP servers support this!

Declaration

public Task<bool> FileExistsAsync(string remotePath, object state = null)

Parameters

Type	Name	Description
String	remotePath	The path of the remote file to check.
Object	state	An optional user-provided object that identifies this particular asynchronous operation.

Returns

Type	Description
Task<Boolean>	True if the file exists, false otherwise.

Implements

IFtp.FileExistsAsync(String, Object)

Remarks

The standard FTP protocol does not have a dedicated command that could be used to detect whether a file exists. There is the MLST command that is quite reliable, but not all server support it and we have to rely on SIZE or even PWD, CWD commands for these servers.
