value = instance.DataSetFieldDescriptor
[NotNull()]
public UADataSetFieldDescriptor DataSetFieldDescriptor {get; set;}

Property Value

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

Remarks

Because the OpcLabs.EasyOpc.UA.PubSub.UADataSetFieldDescriptor has implicit conversions from System.Guid and System.String, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a GUID (representing the dataset field Id), or a string (representing the name of the dataset field) in place of OpcLabs.EasyOpc.UA.PubSub.UADataSetFieldDescriptor value when setting this property, and the corresponding OPC UA dataset field descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.PubSub.UADataSetFieldDescriptor.FromGuid or OpcLabs.EasyOpc.UA.PubSub.UADataSetFieldDescriptor.FromString 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
