C# finally example

In the C# finally block is used, you can clean up any resources that are allocated in a try block, and you can run code even if an exception occurs in.

Syntax

try  
{
  //put suspected c# code here. When an exception occurs, the control will move to the catch block
}
catch
{
 //Catch the exception
}
finally
{
 // clean up resources

C# try-catch-finally Example

using System;  
public class ExExample
{
    public static void Main(string[] args)
    {
  try
        {
            int firstNumber = 10;
            int secondNumber = 0;
            int result = firstNumber / secondNumber;         }
        catch (Exception e) { Console.WriteLine(e); }
        finally { Console.WriteLine("Finally block is executed"); }
        Console.WriteLine("Reset c# code here");
    }

Output

System.DivideByZeroException: Attempted to divide by zero.

Finally block is executed

Rest c# code here

C# finally example if exception is not handled

using System;  
public class ExExample
{
    public static void Main(string[] args)
    {
  try
        {
            int firstNumber = 10;
            int secondNumber = 0;
            int result = firstNumber / secondNumber;
        }
        catch (NullReferenceException e) { Console.WriteLine(e); }
        finally { Console.WriteLine("Finally block is executed"); }
        Console.WriteLine("Rest of the code");
    }
}  

Output

Finally block is executed

Run-time exception (line 11): Attempted to divide by zero.

Stack Trace:
