Equality Operator (DAPropertyDescriptor)



OpcLabs.EasyOpcClassicCore Assembly > OpcLabs.EasyOpc.DataAccess Namespace > DAPropertyDescriptor Class : Equality Operator
First object to be compared.

Because the DAPropertyDescriptor has an implicit conversion from System.Int64, DAPropertyIds, System.Xml.XmlQualifiedName, System.String, DAPropertyId and OpcLabs.EasyOpc.DataAccess.AddressSpace.DAPropertyElement, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a such values in place of this parameter, and the corresponding OPC DA property descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromInt64, FromDAPropertyIds, FromXmlQualifiedName, FromDAPropertyId or FromDAPropertyElementstatic method instead.

The value of this parameter can be null (Nothing in Visual Basic).
