What is IConvertible C#?
The IConvertible interface allows conversion of an object to basic data types and allows the conversion methods in the Convert class to use that object. When implementing the IConvertible interface, create your own type-specific methods for each of the supplied conversion methods.
Which interface should you implement in order to allow instance of your class to be converted to an instance of another type?
In addition to the IConvertible interface, the . NET Framework provides classes called type converters for converting user-defined data types to other data types.
Can I implement multiple interfaces in C#?
2) C# does not support “multiple inheritance” (a class can only inherit from one base class). However, it can be achieved with interfaces, because the class can implement multiple interfaces. Note: To implement multiple interfaces, separate them with a comma (see example below).
Can interface inherit another interface?
Interfaces can inherit from one or more interfaces. The derived interface inherits the members from its base interfaces. A class that implements a derived interface must implement all members in the derived interface, including all members of the derived interface’s base interfaces.
Can two interfaces have same method?
If two interfaces contain a method with the same signature but different return types, then it is impossible to implement both the interface simultaneously. According to JLS (§8.4. 2) methods with same signature is not allowed in this case.
What is difference between inheritance and interface?
Inheritance is the mechanism in java by which one class is allowed to inherit the features of another class. Interface is the blueprint of the class. It specifies what a class must do and not how.
Can a class implement 2 interfaces?
Your class can implement more than one interface, so the implements keyword is followed by a comma-separated list of the interfaces implemented by the class. By convention, the implements clause follows the extends clause, if there is one.
Can we create static method in interface?
Static methods in an interface since java8 Since Java8 you can have static methods in an interface (with body). You need to call them using the name of the interface, just like static methods of a class.
Can an interface inherit another interface?
Can we put static method in interface?
Can interface extends another interface?
An interface can extend other interfaces, just as a class subclass or extend another class. However, whereas a class can extend only one other class, an interface can extend any number of interfaces. The interface declaration includes a comma-separated list of all the interfaces that it extends.
What is the iconvertible interface?
Let’s get started. What is IConvertible Interface? The IConvertible interface basically provides methods that developers can use for the conversion of different types. Once you have decided to implement this interface, you must choose the field/fields within your type to support the conversion.
What is the currentculture parameter in iconvertible?
Most conversion methods have a parameter of type IFormatProvider that represents either the current culture ( CurrentCulture) or a specific culture. For the most part, the IConvertible implementations of the base types ignore this parameter. However, you can choose whether to use it in your code.
What is the best way to implement iconvertible?
Implementing IConvertible is a lot of pain for such legitimate scenarios, and in my opinion waste of precious development time. Best is to implement an abstract method in the base class, which your derived class will implement to return itself. below is the example.
How to implement iconvertible method in a complex class?
Public Class Complex : Implements IConvertible Private x, y As Double Public Sub New (ByVal x As Double, ByVal y As Double) Me.x = x Me.y = y End Sub Function GetDoubleValue () As Double Return Math.Sqrt ( (x * x + y * y)) End Function ‘ The remaining code provides IConvertible method implementations.
