## Methods

### GetInputArguments

Retrieves the input arguments of the method node represented.

<div class="api-signature" data-lang="csharp">

```csharp
public OpcArgumentInfo[] GetInputArguments()
```

</div>

<div class="api-signature" data-lang="vbnet">

```vbnet
Public Function GetInputArguments() As OpcArgumentInfo()
```

</div>

**Returns**

[OpcArgumentInfo](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.client.opcargumentinfo/)[]

An array of [OpcArgumentInfo](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.client.opcargumentinfo/) instances providing the argument information of all arguments used as input argument.

**Remarks**

The time consumed by the first call of the method depends on the availability of the server, because of the arguments are requested on-demand and are cached for subsequent calls. This means, that further argument requests will take use of already retrieved argument information and will not demand additional network resources.

### GetOutputArguments

Retrieves the output arguments of the method node represented.

<div class="api-signature" data-lang="csharp">

```csharp
public OpcArgumentInfo[] GetOutputArguments()
```

</div>

<div class="api-signature" data-lang="vbnet">

```vbnet
Public Function GetOutputArguments() As OpcArgumentInfo()
```

</div>

**Returns**
