What is the meaning of "Provider" in ASP.NET Provider? For example when we are speaking about AuthorizationRuleProvider, connectionStrings.providerName, ...?
回答1:
It's a design pattern: The Provider model. There is some good information in this SO Q&A as well: Designing loosely coupled components in .NET - Provider Pattern
回答2:
It's just a concrete implementation of an abstract interface. You can select an appropriate provider to fulfill the requirements of the interface at runtime.
