| 1. 19. 1. Using finally |
|
|
Sometimes you can define a block of code that will execute when a try/catch block is left. |
The general form of a try/catch that includes finally is shown here: |
|
try {
// block of code to monitor for errors
}
catch (ExcepType1 exOb) {
// handler for ExcepType1
}
catch (ExcepType2 exOb) {
// handler for ExcepType2
}
.
.
.
finally {
// finally code
}
|
|
The finally block will be executed whenever execution leaves a try/catch block. |
|
using System;
class MainClass {
public static void Main() {
Console.WriteLine("Receiving ");
try {
int i=1, j=0;
i = i/j;
}
catch (DivideByZeroException) {
Console.WriteLine("Can't divide by Zero!");
return;
}
catch (IndexOutOfRangeException) {
Console.WriteLine("No matching element found.");
}
finally {
Console.WriteLine("Leaving try.");
}
}
}
