Finally keyword in C#
The finally keyword is used as a block to execute a given set of statements, whether an exception is thrown or not thrown. For example, if you open a file, it must be closed whether an exception is raised or not.
Syntax
Following is the syntax −
try {
// statements causing exception
} catch( ExceptionName e1 ) {
// error handling code
} catch( ExceptionName e2 ) {
// error handling code
} catch( ExceptionName eN ) {
// error handling code
} finally {
// statements to be executed
}Example
Let us see an example to implement the finally block −
using System;
public class Demo {
int result;
Demo() {
result = 0;
}
public void division(int num1, int num2) {
try {
result = num1 / num2;
} catch (DivideByZeroException e) {
Console.WriteLine("Exception caught = {0}", e);
} finally {
Console.WriteLine("Result = {0}", result);
}
}
public static void Main(string[] args) {
Demo d = new Demo();
d.division(100, 0);
}
}Output
This will produce the following output −
Exception caught = System.DivideByZeroException: Attempted to divide by zero. at Demo.division(Int32 num1, Int32 num2) in d:\Windows\Temp
0kebv45.0.cs:line 11 Result = 0
