Do you want to know how to handle division by zero exception in C#? In this tutorial, I will explain how to write a program to demonstrate a division by zero exception in c#.

To demonstrate a division by zero exception in C#, you can write a simple method that performs division and intentionally pass a zero as the denominator. Then, use a try-catch block in your main method to catch and handle the DivideByZeroException. This approach not only simulates the exception but also illustrates how to gracefully handle it in a C# application.

Write A Program To Demonstrate A Division By Zero Exception In C#

Let us first understand what a division by zero exception is. In C#, when you divide any number by zero, the CLR (Common Language Runtime) throws a DivideByZeroException. This exception needs to be handled gracefully to prevent your application from crashing.

Let’s start by writing a simple C# program that demonstrates a division by zero exception. We’ll then extend this example to handle the exception using try-catch blocks.

Step 1: Create a Basic Division Function

First, we create a basic function that performs division:

static double DivideNumbers(int numerator, int denominator)
{
    return numerator / denominator;
}

Step 2: Demonstrate the Exception

Now, let’s use this function in our Main method and intentionally divide by zero:

using System;

class Program
{
    static double DivideNumbers(int numerator, int denominator)
    {
        return numerator / denominator;
    }

    static void Main(string[] args)
    {
        int numerator = 10;
        int denominator = 0;

        double result = DivideNumbers(numerator, denominator);
        Console.WriteLine("Result: " + result);
    }
}

If you run this code, it will throw a DivideByZeroException because the denominator is zero. You can see how the exception appears after I ran the code using a console application in C#.

Step 3: Implement Exception Handling

To handle this division by zero exception in c#, we use a try-catch block:

using System;

class Program
{
    static double DivideNumbers(int numerator, int denominator)
    {
        return numerator / denominator;
    }

    static void Main(string[] args)
    {
        try
        {
            int numerator = 10;
            int denominator = 0;

            double result = DivideNumbers(numerator, denominator);
            Console.WriteLine("Result: " + result);
        }
        catch (DivideByZeroException ex)
        {
            Console.WriteLine("Division by zero is not allowed.");
            Console.WriteLine("Error: " + ex.Message);
        }
    }
}

If a DivideByZeroException occurs, it is caught in the catch block, and a user-friendly message is displayed, preventing the program from crashing.

Once you run the code, you can see how the output appears after I executed the code in C#.
