## ToBase64Transform::TransformBlock method


Processes block of data and copies data to output array.

```cpp
int32_t System::Security::Cryptography::ToBase64Transform::TransformBlock(System::ArrayPtr<uint8_t> inputBuffer, int32_t inputOffset, int32_t inputCount, System::ArrayPtr<uint8_t> outputBuffer, int32_t outputOffset)
```


| Parameter | Type | Description |
| --- | --- | --- |
| inputBuffer | System::ArrayPtr\<uint8_t\> | [Buffer](../../../system/buffer/) to read data from. |
| inputOffset | int32_t | Input buffer offset. |
| inputCount | int32_t | Number of bytes to process. |
| outputBuffer | System::ArrayPtr\<uint8_t\> | Output buffer to copy data into; nullptr to do no copying. |
| outputOffset | int32_t | Output buffer offset. |

### ReturnValue

Number of bytes written.
