.NET Forum / .NET Framework / CLR / July 2006which .NET assembly/class has 'using' inside
Who knows, which .NET assembly/class has 'using' inside? I've tried to check several classes with Reflector but found nothig. I wonder whether .net FW classes use 'using' or everything realized with try...finaly statements by hand? --- WBR, Michael Nemtsev :: blog: http://spaces.msn.com/laflour "At times one remains faithful to a cause only because its opponents do not cease to be insipid." (c) Friedrich Nietzsche The classes don't have *using* in them. *using* is a language element of C#. > Who knows, which .NET assembly/class has 'using' inside?

Because Reflector uses heuristics and pattern-matching to decompile IL. -- Barry  Signaturehttp://barrkel.blogspot.com/ > Who knows, which .NET assembly/class has 'using' inside? > I've tried to check several classes with Reflector but found nothig. Well, as has been pointed out, `using` is a language feature, and produces the same IL as a manual try/finally. > I wonder whether .net FW classes use 'using' or everything realized with > try...finaly statements by hand? Why? Do you think there's some point to avoiding using statements? Signature.NET 2.0 for Delphi Programmers www.midnightbeach.com/.net Delphi skills make .NET easy to learn In print, in stores. Hello Jon, >> I wonder whether .net FW classes use 'using' or everything realized >> with try...finaly statements by hand? JS> Why? Do you think there's some point to avoiding using statements? Just because in case of *using* some initialization code generated before autogenerated *try* statement. I'd like to check how this is realized in FW classes - whether with *using* or not --- WBR, Michael Nemtsev :: blog: http://spaces.msn.com/laflour "At times one remains faithful to a cause only because its opponents do not cease to be insipid."
