Implicit Type Conversion(UAPubSubConnectionDescriptor,ResourceAddress) Operator



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA.PubSub Namespace > UAPubSubConnectionDescriptor Class > Implicit Type Conversion Operator : Implicit Type Conversion(UAPubSubConnectionDescriptor,ResourceAddress) Operator
Network address information in the form of a resource descriptor (can be represented as URL string).

Because the OpcLabs.BaseLib.Networking.ResourceAddress has an implicit conversion from OpcLabs.BaseLib.ResourceDescriptor and System.String, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a OpcLabs.BaseLib.ResourceDescriptor object, or a string (descriptor string - usually a URL) in place of this parameter, and the corresponding resource address will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.BaseLib.Networking.ResourceAddress.FromResourceDescriptor or OpcLabs.BaseLib.Networking.ResourceAddress.FromString static method instead.

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

Converts a resource address to a PubSub connection descriptor.
