Explicit Type Conversion(UABuiltInType,UANodeId) Operator



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.AddressSpace Namespace > UANodeId Class > Explicit Type Conversion Operator : Explicit Type Conversion(UABuiltInType,UANodeId) Operator
The node Id to be converted.

Because the 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 this parameter, 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 UANodeId Constructor(String) constructor instead.

The value of this parameter can be null (Nothing in Visual Basic).

Converts the node Id that represents a data type (data type Id) to a built-in type it corresponds to.

Parameters

nodeId
The node Id to be converted.

Because the 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 this parameter, 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 UANodeId Constructor(String) constructor instead.

The value of this parameter can be null (Nothing in Visual Basic).

Return Value

Returns OpcLabs.EasyOpc.UA.UABuiltInType.Null when nodeId is null or a null node Id (see IsNull). Otherwise, it returns a OpcLabs.EasyOpc.UA.UABuiltInType to which the node Id, treated as a data type Id, corresponds. If the data type Id does not correspond to any built-in type, the method returns OpcLabs.EasyOpc.UA.UABuiltInType.ExtensionObject.
Remarks

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.

OPC UA node Id, represented by the UANodeId class, directly identifies a node in a server's address space.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
