Property Value

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

Remarks

Because the OpcLabs.EasyOpc.UA.PubSub.UASubscribeDataSetFilter has an implicit conversion from OpcLabs.EasyOpc.UA.PubSub.UAPublisherId, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a OpcLabs.EasyOpc.UA.PubSub.UAPublisherId (containing the publisher Id that you want to allow in the filter) in place of OpcLabs.EasyOpc.UA.PubSub.UASubscribeDataSetFilter value when setting this property, and the corresponding OPC UA subscribe dataset filter will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromUAPublisherId static method instead.

This member or type is for use from COM. It is not meant to be used from .NET or Python. Refer to the corresponding .NET member or type instead, if you are developing in .NET or Python.

Requirements

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