## TcpClient::BeginConnect(String, int32_t, AsyncCallback, System::SharedPtr\<Object\>) method


Initiates an asynchronous connect operation.

```cpp
System::SharedPtr<IAsyncResult> System::Net::Sockets::TcpClient::BeginConnect(String host, int32_t port, AsyncCallback requestCallback, System::SharedPtr<Object> state)
```


| Parameter | Type | Description |
| --- | --- | --- |
| host | String | A remote host name. |
| port | int32_t | A port of the remote host. |
| requestCallback | AsyncCallback | A callback that will be called when the operation completes. |
| state | System::SharedPtr\<Object\> | User-provided data used to uniquely identify each asynchronous connect operation. |

### ReturnValue

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