Flow control in try catch finally in C#
The flow control in try, catch, and finally can be understood using the following example. Here, we are dividing two numbers −
Example
using System;
namespace ErrorHandlingApplication {
class DivNumbers {
int result;
DivNumbers() {
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);
}
}
static void Main(string[] args) {
DivNumbers d = new DivNumbers();
d.division(25, 0);
Console.ReadKey();
}
}
}Output
Exception caught: System.DivideByZeroException: Attempted to divide by zero. at ErrorHandlingApplication.DivNumbers.division (System.Int32 num1, System.Int32 num2) [0x00000] in :0 Result: 0
The following shows the flow control in exceptions handling using try catch finally in C#
- If an exception occurs in try block, then the control transfers to the catch block.
- After the catch block finish, then the finally block works.
- If no exception occurs, then firstly the try occurs and then the flow control to finally block
