Inherits members from [OpcVariableNodeInfo](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.client.opcvariablenodeinfo/members), [OpcInstanceNodeInfo](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.client.opcinstancenodeinfo/members), [OpcNodeInfo](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.client.opcnodeinfo/members).

## Properties

### NamespaceUri

Gets the value of the NamespaceUri child node of the data type dictionary node represented.

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

```csharp
public string NamespaceUri { get; }
```

</div>

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

```vbnet
Public ReadOnly Property NamespaceUri As String
```

</div>

**Property value**

[String](https://learn.microsoft.com/dotnet/api/system.string)

A [string](https://learn.microsoft.com/dotnet/api/system.string) which represents the value of the NamespaceUri child node of the data type dictionary node.

**Remarks**

The time consumed by the first call of the property depends on the availability of the server, because of the [Value](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcattribute/#value) attribute of the NamespaceUri child node is requested on-demand and is cached for subsequent calls. This means, that further requests to this property will take use of already retrieved attribute information and will not demand additional network resources.

## Methods

### GetDescriptions

Retrieves all nodes which are referenced using the [HasComponent](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.opcreferencetype/#hascomponent) reference for which the according [OpcNodeInfo](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.client.opcnodeinfo/) is represented by the [OpcDataTypeDescriptionNodeInfo](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.client.opcdatatypedescriptionnodeinfo/) class.

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

```csharp
public OpcDataTypeDescriptionNodeInfo[] GetDescriptions()
```

</div>

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

```vbnet
Public Function GetDescriptions() As OpcDataTypeDescriptionNodeInfo()
```

</div>

**Returns**

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

An array of [OpcDataTypeDescriptionNodeInfo](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.client.opcdatatypedescriptionnodeinfo/) objects referenced by the current [OpcDataTypeDictionaryNodeInfo](https://www.traeger.de/en/docs/development/opcua/api/v2.59/opc.uafx.client.opcdatatypedictionarynodeinfo/).

**Remarks**

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