## Constructors

### ByteString

Initializes a new [ByteString](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.bytestring/) from the `value` specified.

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

```csharp
public ByteString(params byte[] value)
```

</div>

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

```vbnet
Public Sub New(ParamArray value As Byte())
```

</div>

**Parameters**

| Name | Type | Description |
|---|---|---|
| `value` | params [Byte](https://learn.microsoft.com/dotnet/api/system.byte)[] | The array of [byte](https://learn.microsoft.com/dotnet/api/system.byte) values to represent or a null reference (Nothing in Visual Basic). |

**Remarks**

If `value` is a null reference (Nothing in Visual Basic) an empty array of [byte](https://learn.microsoft.com/dotnet/api/system.byte) values is used.

## Properties

### Length

Gets the total number of elements in all the dimensions of the [ByteString](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.bytestring/).
