How do I get deterministic finalization in C#?

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.

That is true. A class implementing the interface IDisposable can be used in the using statement, something like:

Code
span style="font-style: italic;">// This line of code calls another function of this object, which actually disposes the resources used


        GC.SuppressFinalize(this);    // This line specifies that GC should now ignore this object from its usual garbage collection cycle// Code here for freeing up the resources used by this object, performing checks for it being null or already disposed


    }
