Properties

Item[Int32]

Gets the key with the specified offset.

Declaration
public string this[int offset] { get; }
Parameters
Type Name Description

The System.String.

Methods

Add(String, Byte[])

Adds the specified fingerprint data and associates it with the specified key.

Declaration
public void Add(string key, byte[] fingerprintData)
Parameters
Type Name Description
System.String key

The key.
System.Byte[] fingerprintData

The fingerprint data.

Add(String, EnrollStageResult)

Adds the specified fingerprint data and associates it with the specified key.

Declaration
public void Add(string key, EnrollStageResult enrollResult)
Parameters
Type Name Description
System.String key

The key.
EnrollStageResult enrollResult

The enroll result.

AddRange(IEnumerable<Tuple<String, Byte[]>>)

Adds the specified fingerprint key-value pairs to the gallery. This is the preferred method for bulk loading as it does not rebuild the database for every fingerprint.

Declaration
public void AddRange(IEnumerable<Tuple<string, byte[]>> fingerprints)
Parameters
Type Name Description
System.Collections.Generic.IEnumerable<System.Tuple<System.String, System.Byte[]>> fingerprints

The fingerprints.

AllKeys()

Gets all the keys registered in this gallery.

Declaration
public string[] AllKeys()
Returns
Type Description
System.String[]

Dispose()

Declaration
public void Dispose()

Dispose(Boolean)

Releases unmanaged and - optionally - managed resources.

Declaration
protected virtual void Dispose(bool releaseOnlyManaged)
Parameters
Type Name Description
System.Boolean releaseOnlyManaged

true to release both managed and unmanaged resources; false to release only unmanaged resources.

Finalize()

Declaration
protected void Finalize()

HasKey(String)

Determines whether the gallery contains the specified keys.

Declaration
public bool HasKey(string key)
Parameters
Type Name Description
System.String key

The key.
Returns
Type Description
System.Boolean

Remove(String)

Removes a fingerprint from the gallery given its key

Declaration
public void Remove(string key)
Parameters
Type Name Description
System.String key

The key.
