UAAttributeFieldCollection Constructor(UAAttributeField[])



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA Namespace > UAAttributeFieldCollection Class > UAAttributeFieldCollection Constructor : UAAttributeFieldCollection Constructor(UAAttributeField[])

Because the UAAttributeField has an implicit conversion from OpcLabs.EasyOpc.UA.Filtering.UASimpleAttributeOperand, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a OpcLabs.EasyOpc.UA.Filtering.UASimpleAttributeOperand in place of this parameter, and the corresponding OPC UA attribute field will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromUASimpleAttributeOperand static method instead.

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

The individual elements of the parameter value can be null (Nothing in Visual Basic).

Initializes a new instance of the collection, with given array of items.
