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


从流中读取指定数量的字节并将其写入指定的字节数组。

```cpp
int32_t System::IO::MemoryStream::Read(const ArrayPtr<uint8_t> &buffer, int32_t offset, int32_t count) override
```


| 参数 | 类型 | 描述 |
| --- | --- | --- |
| buffer | 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

读取的字节数
