What is method overloading in C#?
Two or more than two methods having the same name but different parameters is what we call method overloading in C#.
Method overloading in C# can be performed by changing the number of arguments and the data type of the arguments.
Let’s say you have a function that prints multiplication of numbers, then our overloaded methods will have the same name but different number of arguments −
public static int mulDisplay(int one, int two) { } public static int mulDisplay(int one, int two, int three) { } public static int mulDisplay(int one, int two, int three, int four) { }
The following is an example showing how to implement method overloading −
Example
using System; public class Demo { public static int mulDisplay(int one, int two) { return one * two; } public static int mulDisplay(int one, int two, int three) { return one * two * three; } public static int mulDisplay(int one, int two, int three, int four) { return one * two * three * four; } } public class Program { public static void Main() { Console.WriteLine("Multiplication of two numbers: "+Demo.mulDisplay(10, 15)); Console.WriteLine("Multiplication of three numbers: "+Demo.mulDisplay(8, 13, 20)); Console.WriteLine("Multiplication of four numbers: "+Demo.mulDisplay(3, 7, 10, 7)); } }
Output
Multiplication of two numbers: 150 Multiplication of three numbers: 2080 Multiplication of four numbers: 1470
