'Declaration
 
Public Property Filter As UASubscribeDataSetFilter
'Usage
 
Dim instance As EasyUADataSetSubscriptionChangeArguments
Dim value As UASubscribeDataSetFilter
 
instance.Filter = value
 
value = instance.Filter
public UASubscribeDataSetFilter Filter {get; set;}
public:
property UASubscribeDataSetFilter^ Filter {
   UASubscribeDataSetFilter^ get();
   void set (    UASubscribeDataSetFilter^ value);
}

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.

Requirements

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