IntrinsicDataTypeDescriptionFromDataTypeId Method



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.DataTypeSchema Namespace > UADataTypeSchema Class : IntrinsicDataTypeDescriptionFromDataTypeId Method
The data type ID for which the intrinsic data type description should be returned.

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 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 cannot be null (Nothing in Visual Basic).

Finds an intrinsic data type description for a given data type ID.

Parameters

dataTypeId
The data type ID for which the intrinsic data type description should be returned.

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 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 cannot be null (Nothing in Visual Basic).

Return Value

Returns a data type description for the dataTypeId, if it refers to an intrinsic data type. Otherwise, returns null.

This method can return null (Nothing in Visual Basic).
