What are multiple inheritances in C#?
C# does not support the usage of multiple inheritances, but it can be implemented using interfaces.
The following is an implementation of Inheritance with Interface. Create two interfaces −
public interface BaseOne {
void display();
}
public interface BaseTwo {
void display();
}Now set the interfaces like you set the derived classes,
public class ChildOne : BaseOne, BaseTwo {
public void display() {
Console.WriteLine("Child Class!");
}
}We will call the child class function as shown in the following code to implement multiple inheritance in C# −
Example
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Demo {
class Program {
static void Main(string[] args) {
ChildOne c = new ChildOne();
c.display();
Console.ReadKey();
}
}
public interface BaseOne {
void display();
}
public interface BaseTwo {
void display();
}
public class ChildOne : BaseOne, BaseTwo {
public void display() {
Console.WriteLine("Child Class!");
}
}
}
