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.

   at ExExample.Main(String[] args) in d:\Windows\Temp\fxh13qx1.0.cs:line 11

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.
