The using Statement
Updated: there is no inner try...catch in the outer finally block, readers who mentioned it are right! Thanks!
Together with the lock statement, the using keyword is also relatively mysterious:
using (IDisposable instance = ...)
{
//do something
}
is equal to:
IDisposable instance = ...;
try
{
//do something
}
finally
{
if (instance != null)
{
instance.Dispose();
}
}
