HashAlgorithm.TransformFinalBlock Method

Computes the hash value for the specified region of the specified byte array.

Namespace:  System.Security.Cryptography
Assembly:  mscorlib (in mscorlib.dll)

'Declaration
Public Function TransformFinalBlock ( _
	inputBuffer As Byte(), _
	inputOffset As Integer, _
	inputCount As Integer _
) As Byte()

Parameters

inputBuffer
Type: System.Byte()
The input to compute the hash code for.
inputOffset
Type: System.Int32
The offset into the byte array from which to begin using data.
inputCount
Type: System.Int32
The number of bytes in the byte array to use as data.

Return Value

Type: System.Byte()
An array that is a copy of the part of the input that is hashed.

Implements

ICryptoTransform.TransformFinalBlock(Byte(), Int32, Int32)

ExceptionCondition
ArgumentException

inputCount uses an invalid value.

-or-

inputBuffer has an invalid offset length.

ArgumentNullException

inputBuffer is Nothing.

ArgumentOutOfRangeException

inputOffset is out of range. This parameter cannot be a non-negative number.

ObjectDisposedException

The object has already been disposed.

You must call the TransformFinalBlock method after calling the TransformBlock method but before you retrieve the final hash value.

Note that the return value of this method is not the hash value, but only a copy of the hashed part of the input data. To retrieve the final hashed value after calling the TransformFinalBlock method, get the byte array contained in the Hash property.
