1. How do you implement multiple inheritance in C#? 2. What is INotifiedPropertyChanged?

Question

Accepted Answer

1. Multiple inheritance in C# can be achieved using interfaces. 2. INotifyPropertyChanged is an interface used for data binding in WPF and Silverlight applications.

Multiple inheritance in C# can be implemented using interfaces, as C# does not support multiple inheritance of classes.
Create multiple interfaces and implement them in a single class to achieve multiple inheritance.
Example: interface Interface1 { void Method1(); } interface Interface2 { void Method2(); } class MyClass : Interface1, Interface2 { public void Method1() { // implementation } public void Method2() { // implementation } }
INotifyPropertyChanged is an interface in the System.ComponentModel namespace used for data binding in WPF and Silverlight applications.
It is used to notify clients, typically binding clients, that a property value has changed.
Example: public class Person : INotifyPropertyChanged { private string name; public string Name { get { return name; } set { name = value; OnPropertyChanged(nameof(Name)); } } public event PropertyChangedEventHandler PropertyChanged; protected void OnPropertyChanged(string propertyName) { PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName)); } }
