## Decoder::GetCharCount(ArrayPtr\<uint8_t\>, int, int) method


Gets the number of characters needed to decode a buffer.

```cpp
virtual int System::Text::Decoder::GetCharCount(ArrayPtr<uint8_t> bytes, int index, int count)
```


| Parameter | Type | Description |
| --- | --- | --- |
| bytes | ArrayPtr\<uint8_t\> | Bytes to decode. |
| index | int | [Buffer](../../../system/buffer/) offset. |
| count | int | Number of bytes to decode. |

### ReturnValue

Number of characters required to decode the buffer.
