Implicit vs. Explicit Interface Implementation in C#: When Should I Choose Which?

C# interface hidden and explicit implementation: When will it be selected?

Introduction:

When the interface is implemented in C#, developers can choose hidden implementation or explicit implementation. Understanding the differences between the two and the appropriate usage scenario are essential for writing efficient and easy -to -maintain code.

Into the implementation:

Illusal implementation refers to the members of the interface as a member of the implementation class. In this case, the compiler generates the necessary code to meet the interface contract, and members who implement the class can be accessed as a class member or as a member of the interface.

Expressing implementation:

On the other hand, explicit implementation refers to the use of grammar to expand the interface method in the implementation class. This method can more finely control the implementation of the interface and allow multiple interfaces at the same time.

When to use hidden and explicit implementation:

interfaceName.methodSignature

When a member of the implementation class directly represents the contract of the interface, the preferred hidden formation is implemented. This simplifies the code and can easily access the interface members through class and interface references.

In the following circumstances, it is appropriate to expand the implementation:

When the names or semantics of the implementation class are different from the corresponding interface members.

When multiple interfaces need to be implemented, and the class hopes to provide different implementation for each interface.

When controlling the visibility of the interface members in the class, the visibility of the interface members in the class.
• advantages and disadvantages:
Into the implementation:

Advantages:

The code is more concise and clear

Can be used for attributes and indexers

• Disadvantages:
  It may cause the naming conflict with other members
  Unable to explicitly control the implementation details
• Expressing implementation:
  • Advantages:
better control interface implementation

Support multiple interface implementation Improving code readability

• Disadvantages:
  • Need additional code to achieve the interface method
  • may make the code more complicated
The guidance principles and modern practice before IOC:
• As mentioned in the problem, before the IOC era, Microsoft's guidance principles do not encourage explicit implementation. However, with the emergence of dependency injection and service -oriented architecture, it has achieved more correlations, and is often used with interface -based DI containers.
  • Conclusion:
  Ciseple and explicit interface implementation provides different advantages and use cases in C# programming, respectively. By understanding the differences between these methods, developers can effectively design and implement classes that meet specific interface contracts, while maintaining maintenanceability and code clarity.
