.NET Framework Exceptions Using a finally block
Example
The finally { ... } block of a try-finally or try-catch-finally will always execute, regardless of whether an exception occurred or not (except when a StackOverflowException has been thrown or call has been made to Environment.FailFast()).
It can be utilized to free or clean up resources acquired in the try { ... } block safely.
Console.Write("Please enter a filename: ");
string filename = Console.ReadLine();
Stream fileStream = null;
try
{
fileStream = File.Open(filename);
}
catch (FileNotFoundException)
{
Console.WriteLine("File '{0}' could not be found.", filename);
}
finally
{
if (fileStream != null)
{
fileStream.Dispose();
}
}
