## Stream::Read(const ArrayPtr\<uint8_t\>\&, int32_t, int32_t) method


从流中读取指定数量的字节并将它们写入指定的字节数组。

```cpp
virtual int32_t System::IO::Stream::Read(const ArrayPtr<uint8_t> &buffer, int32_t offset, int32_t count)=0
```


| Parameter | Type | 描述 |
| --- | --- | --- |
| 缓冲区 | const ArrayPtr\<uint8_t\>\& | 用于写入读取字节的字节数组 |
| offset | int32_t | 在 **buffer** 中开始写入的 0 基位置 |
| count | int32_t | 要读取的字节数 |

### ReturnValue

已读取的字节数
