try-catch-finally (C# Reference)
Visual Studio 2005
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.
For more information and examples on re-throwing exceptions, see try-catch and Throwing Exceptions.
// try_catch_finally.cs
using System;
public class EHClass
{
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.");
}
}
}
Sample Output
