C# Methods

A method in C# is a block of code that performs a particular task. Methods help you reuse code, keep it organized, and make it easier to read and maintain.

Basic Method Syntax

returnType MethodName(parameters)
{
    // code to execute
}
  

Example: Simple Method

using System;

class Program
{
    static void Greet()
    {
        Console.WriteLine("Hello, welcome to C#!");
    }

    static void Main()
    {
        Greet(); // Call the method
    }
}
  

Method with Parameters

static void PrintMessage(string name)
{
    Console.WriteLine("Hello " + name);
}

static void Main()
{
    PrintMessage("Technorank");
}
  

Method with Return Value

static int Add(int a, int b)
{
    return a + b;
}

static void Main()
{
    int result = Add(5, 7);
    Console.WriteLine(result);  // Output: 12
}
  

Method Overloading

You can define multiple methods with the same name but different parameters.

static int Multiply(int a, int b)
{
    return a * b;
}

static double Multiply(double a, double b)
{
    return a * b;
}

static void Main()
{
    Console.WriteLine(Multiply(4, 3));       // 12
    Console.WriteLine(Multiply(2.5, 4.2));   // 10.5
}
