In a garbage collected environment, it's impossible to get true determinism. However, a design pattern that we recommend is implementing IDisposable on any class that contains a critical resource. Whenever this class is consumed, it may be placed in a using statement, as shown in the following example:

using(FileStream myFile = File.Open(@"c:temptest.txt",

FileMode.Open))

{

int fileOffset = 0;

while(fileOffset < myFile.Length)

{

Console.Write((char)myFile.ReadByte());

fileOffset++;

}

}

When myFile leaves the lexical scope of the using, its dispose method will be called.
