DataTypeEncodingId Property (UAExtensionObject)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA Namespace > UAExtensionObject Class : DataTypeEncodingId Property
The data type encoding node ID for the extension object.
Syntax
'Declaration
 
Public Property DataTypeEncodingId As UANodeId
'Usage
 
Dim instance As UAExtensionObject
Dim value As UANodeId
 
instance.DataTypeEncodingId = value
 
value = instance.DataTypeEncodingId
public UANodeId DataTypeEncodingId {get; set;}
public:
property UANodeId^ DataTypeEncodingId {
   UANodeId^ get();
   void set (    UANodeId^ value);
}

Property Value

The value of this property cannot be null (Nothing in Visual Basic).

Because there is an implicit conversion from OpcLabs.EasyOpc.UA.AddressSpace.UANodeId to UANodeDescriptor, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned OpcLabs.EasyOpc.UA.AddressSpace.UANodeId in any place where the UANodeDescriptor is expected as input, and the corresponding node descriptor will be constructed automatically.

Also, because the OpcLabs.EasyOpc.UA.AddressSpace.UANodeId has an implicit conversion to System.String, and it converts to the expanded text of the node Id (OpcLabs.EasyOpc.UA.AddressSpace.UANodeId.ExpandedText), in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use the returned OpcLabs.EasyOpc.UA.AddressSpace.UANodeId in any place where expanded text of a node Id (a string) is expected as input, and the corresponding expanded text will be taken automatically from the node Id.

Remarks

Because the OpcLabs.EasyOpc.UA.AddressSpace.UANodeId has an implicit conversion from System.String, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a string (representing the expanded text of the nodeId) in place of OpcLabs.EasyOpc.UA.AddressSpace.UANodeId value when setting this property, and the corresponding OPC UA node Id will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.AddressSpace.UANodeId.UANodeId Constructor(String) constructor instead.
