Begins asynchronous GetRemoteChecksum operation. Returns the checksum of the specified file on the server.

Namespace:  Rebex.Net
Assembly:  Rebex.Ftp (in Rebex.Ftp.dll)

Syntax

Visual Basic
Public Function BeginGetRemoteChecksum ( _
	type As FtpChecksumType, _
	remotePath As String, _
	offset As Integer, _
	count As Long, _
	callback As AsyncCallback, _
	state As Object _
) As IAsyncResult
C#
public IAsyncResult BeginGetRemoteChecksum(
	FtpChecksumType type,
	string remotePath,
	int offset,
	long count,
	AsyncCallback callback,
	Object state
)

Parameters

type
Type: Rebex.Net..::..FtpChecksumType
Desired checksum type (server must support it - see GetSupportedChecksumTypes()()()() for details).
remotePath
Type: System..::..String
Path of the remote file.
offset
Type: System..::..Int32
The offset in remote file where reading will start.
count
Type: System..::..Int64
The maximum number of bytes to read.
callback
Type: System..::..AsyncCallback
An optional asynchronous callback to be called when the operation is complete.
state
Type: System..::..Object
A user-provided object that identifies this particular asynchronous operation.

Return Value

An IAsyncResult that references the asynchronous operation.

Remarks

Please note that not all FTP server that support checksums will necessarily support this variant as well.

To calculate checksums of local files, use one of CalculateLocalChecksum(FtpChecksumType, String, Int32, Int64) methods.

In builds for .NET 4.0 and higher, this method is available as an extension method. Add 'using Rebex.Legacy' (C#) or 'Import Rebex.Legacy' (VB.NET) to your code in order to use it.
