RijndaelManagedTransform.TransformFinalBlock Method

Note: This method is new in the .NET Framework version 2.0.

Computes the transformation for the specified region of the specified byte array.

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

public byte[] TransformFinalBlock (
	byte[] inputBuffer,
	int inputOffset,
	int inputCount
public final byte[] TransformFinalBlock (
	byte[] inputBuffer, 
	int inputOffset, 
	int inputCount
public final function TransformFinalBlock (
	inputBuffer : byte[], 
	inputOffset : int, 
	inputCount : int
) : byte[]



The input to perform the operation on.


The offset into the byte array to begin using data from.


The number of bytes in the byte array to use as data.

Return Value

The computed transformation.

Exception typeCondition


The inputBuffer parameter is a null reference (Nothing in Visual Basic).


The value of the inputCount parameter is less than 0.


The value of the inputCount parameter is grater than the length of inputBuffer parameter.


The value of the inputOffset parameter is negative.


The length of the inputCount parameter is not evenly devisable by input block size.

The following code example demonstrates how to call the TransformFinalBlock method to transform the final block of bytes. This code example is part of a larger example provided for the RijndaelManagedTransform class.

byte[] finalBytes = rijTransform.TransformFinalBlock(
    sourceByteLength - currentPosition);
