the class can provide an implementation of an interface only one time and only if the class declares the interface as part of the definition of the class (class ClassName : InterfaceName). If the interface is inherited because you inherited a base class that implements the interface, the base...

When an interface method call is selected, "Go to Definition" jumps to the definition of the symbol (in this case, an interface method) whereas "Go to Implementations" shows all the corresponding concrete methods. The first operation is strictly about the reference graph (which relates references...
Here's the interface definition for a customer:C# Copy public interface ICustomer { IEnumerable<IOrder> PreviousOrders { get; } DateTime DateJoined { get; } DateTime? LastOrder { get; } string Name { get; } IDictionary<DateTime, string> Reminders { get; } } ...
The attribute should be applied when defining an interface member and not added or removed later.Span<Span<T>>This combination of features does not allow for constructs such as Span<Span<T>>. This is made a bit clearer by looking at the definition of Span<T>:...
Having promised to implement the interface, the structure must define implementations of all of the functions declared in the interface. As in Java and C#, the implementations of the methods must be defined inside the structure definition.
The keywords interface and end, which mark the start and end of the definition, are optional when you use lightweight syntax. If you do not use these keywords, the compiler attempts to infer whether the type is a class or an interface by analyzing the constructs that you use. If you def...
(If you were using implExtern, this definition would be extern likewise.)Note that inside function implementations, we use VSELF, which simply casts the parameter introduced by VSelf to a user-defined type (const Rectangle or Rectangle in our case):int Rectangle_perim(const VSelf) { VSELF(...
