Syntax
'Declaration
 
Public Property PublisherId As UAPublisherId
'Usage
 
Dim instance As UAPubSubConnectionElement
Dim value As UAPublisherId
 
instance.PublisherId = value
 
value = instance.PublisherId
public UAPublisherId PublisherId {get; set;}
public:
property UAPublisherId^ PublisherId {
   UAPublisherId^ get();
   void set (    UAPublisherId^ value);
}

Property Value

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

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 the returned OpcLabs.EasyOpc.UA.PubSub.UAPublisherId (containing the publisher Id that you want to allow in the filter) in any place where OpcLabs.EasyOpc.UA.PubSub.UASubscribeDataSetFilter is expected as input, 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.

Requirements

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