try-catch-finally
Visual Studio .NET 2003
A common usage of catch and finally together is to obtain and use resources in a try block, deal with exceptional circumstances in a catch block, and release the resources in the finally block.
Example
// try-catch-finally
using System;
public class EHClass
{
public static void Main ()
{
try
{
Console.WriteLine("Executing the try statement.");
throw new NullReferenceException();
}
catch(NullReferenceException e)
{
Console.WriteLine("{0} Caught exception #1.", e);
}
catch
{
Console.WriteLine("Caught exception #2.");
}
finally
{
Console.WriteLine("Executing finally block.");
}
}
}
Output
Executing the try statement. System.NullReferenceException: Attempted to dereference a null object reference. at EHClass.Main() Caught exception #1. Executing finally block.
