using(OpenFileDialog dlg ...) dispose issue

[Austin Jan]

Hi all,

In this code snip

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

if CLR throw FileOntFoundException 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/d...ry/en-us/csspec/html/vclrfcsharpspec_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)dlg).Dispose();
}
}
