Session.CompareDirectories Method

Compares directories, the same way Session.SynchronizeDirectories method does, but returns differences only.

This feature is available only in the latest beta release.


public ComparisonDifferenceCollection CompareDirectories(
    SynchronizationMode mode,
    string localPath,
    string remotePath,
    bool removeFiles,
    bool mirror = false,
    SynchronizationCriteria criteria = SynchronizationCriteria.Time,
    TransferOptions options = null
Public Function CompareDirectories(
    mode As SynchronizationMode,
    localPath As String,
    remotePath As String,
    removeFiles As Boolean,
    Optional mirror As Boolean = False,
    Optional criteria As SynchronizationCriteria = 1,
    Optional options As TransferOptions = Nothing
) As ComparisonDifferenceCollection


Name Description
SynchronizationMode mode Synchronization mode. Possible values are SynchronizationMode.Local, SynchronizationMode.Remote and SynchronizationMode.Both.
string localPath Full path to local directory.
string remotePath Full path to remote directory.
bool removeFiles When set to true, considered obsolete files to be deleted. Cannot be used for SynchronizationMode.Both.
bool mirror When set to true, compares in mirror mode (synchronizes also older files). Cannot be used for SynchronizationMode.Both. Defaults to false.
SynchronizationCriteria criteria Comparison criteria. Possible values are SynchronizationCriteria.None, SynchronizationCriteria.Time (default), SynchronizationCriteria.Size and SynchronizationCriteria.Either. For SynchronizationMode.Both SynchronizationCriteria.Time can be used only.
TransferOptions options Transfer options. Defaults to null, what is equivalent to new TransferOptions(). Only few properties matter for comparison, notably the TransferOptions.FileMask.

Return Value

ComparisonDifferenceCollection - a read-only collection of differences. See ComparisonDifference.
