 |
|
I was going through the examples in the C# book for 316. As a VB6.0, Fortran
and C++ programmer I was troubled by what I was doing. Below is a short
example I wrote to demonstrate my puzzlement.
Is this good coding in a managed environment? Just create new objects on the
heap and ignore them when you are done? Will they be taken care of when the
system does clean up? Shouldn't I destroy them myself?
for (int i = 0 ; i < 10; i++)
{
int p = new int();
p = i;
System.Console.WriteLine (place);
}
Thanks for the help

System.Console.WriteLine (p); // forgot to change this variable to p also
Edward sorry
}

Yep, that should be ok afaik.
The difficulty comes when you are using types defined in unmanaged code.
Then you have to implement the dispose pattern and clean up after yourself.

Well after years and years of cleaning up after myself, this managed code
just makes me nervous.

Edward,
Have a look at the following URL:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/dotnetGCbasics.asp
It explains how .NET implements garbage collection and why you should
never need to worry about cleaning up after yourself again!

I haven't watched it yet, but from the blurbs I think you might also be
interested in the Jason Zander interview posted to channel 9 today
