## NetworkStream::BeginRead method


Initiates an asynchronous read operation.

```cpp
System::SharedPtr<IAsyncResult> System::Net::Sockets::NetworkStream::BeginRead(System::ArrayPtr<uint8_t> buffer, int32_t offset, int32_t size, AsyncCallback callback, System::SharedPtr<Object> state) override
```


| Parameter | Type | Description |
| --- | --- | --- |
| buffer | System::ArrayPtr\<uint8_t\> | The byte array where the read bytes will be written. |
| offset | int32_t | The offset in bytes in the specified array. |
| size | int32_t | The number of bytes to read. |
| callback | AsyncCallback | A callback to be called when the operation completes. |
| state | System::SharedPtr\<Object\> | User-provided data used to uniquely identify each asynchronous read operation. |

### ReturnValue

An [IAsyncResult](../../../system/iasyncresult/) object representing the initiated asynchronous read operation.
