using(OpenFileD ialog dlg ...) dispose issue

[Austin Jan]

Hi all,

In this code snip

try
{
using(OpenFileD ialog dlg = new OpenFileDialog( ))
{
//do something
}
}
catch
{
//do someting
}

if CLR throw FileOntFoundExc eption in try block, Will dlg call
dlg.Dispose() finally?

thanks.

It should get disposed as indicated in the C# spec.
http://msdn.microsoft.com/library/de...pspec_8_13.asp

The following code...

using (OpenFileDialog dlg = new OpenFileDialog( ))
{
//do something
}

....should get expanded to something like this...

OpenFileDialog dlg = new OpenFileDialog( );
try
{
//do something
}
finally
{
if (dlg != null)
{
((IDisposable)d lg).Dispose();
}
}
