HashAlgorithm::TransformFinalBlock Method
Computes the hash value for the specified region of the specified byte array.
Assembly: mscorlib (in mscorlib.dll)
public: virtual array<unsigned char>^ TransformFinalBlock( array<unsigned char>^ inputBuffer, int inputOffset, int inputCount ) sealed
Parameters
- inputBuffer
- Type: array<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: array<System::Byte>An array that is a copy of the part of the input that is hashed.
Implements
ICryptoTransform::TransformFinalBlock(array<Byte>, Int32, Int32)| Exception | Condition |
|---|---|
| ArgumentException | inputCount uses an invalid value. -or- inputBuffer has an invalid offset length. |
| ArgumentNullException | inputBuffer is nullptr. |
| ArgumentOutOfRangeException | inputOffset is out of range. This parameter requires 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.
The following code examples use the TransformFinalBlock method with the TransformBlock method to hash a string.
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
