DataSetClassId Property (UAUadpDataSetReaderMessageParameters)

Defines a dataset class related filter.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
<TypeConverterAttribute(System.ComponentModel.GuidConverter)>
Public Property DataSetClassId As Guid

'Usage
 
Dim instance As UAUadpDataSetReaderMessageParameters
Dim value As Guid
 
instance.DataSetClassId = value
 
value = instance.DataSetClassId

[TypeConverter(System.ComponentModel.GuidConverter)]
public Guid DataSetClassId {get; set;}

[TypeConverter(System.ComponentModel.GuidConverter)]
public:
property Guid DataSetClassId {
   Guid get();
   void set (    Guid value);
}

Remarks

If the value is System.Guid.Empty, the dataset class Id filter is not applied.

There are two places where data set class ID can be entered: In the UADataSetMetaData.DataSetClassId property of the UADataSetMetaData, and in the DataSetClassId property of the UAUadpDataSetReaderMessageParameters. In the end, setting either one of these to non-empty System.Guid will have the same effect. We recommend that you use the DataSetClassId property of the OpcLabs.EasyOpc.UA.PubSub.UASubscribeDataSetFilter. If you set both these properties to a non-empty System.Guid, make sure you use the same value at both places, otherwise no data set message will pass the filter.

If you have a OpcLabs.EasyOpc.UA.PubSub.UADataSetSubscriptionDescriptor, the two places mentioned above are:
