## ToBase64Transform::TransformBlock method


处理数据块并将数据复制到输出数组。

```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)
```


| 参数 | 类型 | 描述 |
| --- | --- | --- |
| inputBuffer | System::ArrayPtr\<uint8_t\> | [Buffer](../../../system/buffer/) 用于读取数据。 |
| inputOffset | int32_t | 输入缓冲区偏移量。 |
| inputCount | int32_t | 要处理的字节数。 |
| outputBuffer | System::ArrayPtr\<uint8_t\> | 用于复制数据的输出缓冲区；若为 nullptr 则不进行复制。 |
| outputOffset | int32_t | 输出缓冲区偏移量。 |

### ReturnValue

已写入的字节数。
