Sometimes , it might be necessary to define a block of code that needs to be executed regardless of the exception.
For example , you might want to close the database connection or close the file .
finally block can usually be used for this purpose.
public void Data(params int[] datum)
{
int val = 0;
try
{
foreach (var da in datum)
{
val = val + da;
}
}
finally
{
val = 0;
}
}
