What is the .NET object life cycle?

Question

What is the object life cycle for an object in .NET?

From what I understand it is:

1. Object created - constructor called (if one exists)
2. Methods

Answer 1

Here is an example class that uses all the information available in the articles provided here. I have already spent hours testing things out, and this is what works best for me.

using System;
using System.IO;

public class MyClass : IDisposable
{
    String oFile;
    Stream oStream;

    public MyClass(String _File)
    {
        oStream = File.OpenRead(oFile = _File);
        // Initialize
    }

    ~MyClass()
    {
        this.Dispose();
        // Destruct
    }

    public void doSomething()
    {
        // do Whatever it is you are trying to do
    }

    #region IDisposable Members

    /// 

    /// Dispose all resources used by instance of class
    /// and update Garbage Collector information
    /// 
    public void Dispose()
    {
        if (oStream != null)
        {
            oStream.Dispose(); // Dispose using built in functions
            GC.SuppressFinalize(oStream); // No need for Garbage Collector
        }

        oStream = null;  // Nullify it.
    }

    #endregion
}

Usage:

using(MyClass mc = new MyClass(@"c:\temp\somefile.txt"))
{
  mc.doSomething();
}

You can even use the same declaration twice as it does not exist outside the 'using'.

using(MyClass mc = new MyClass(@"c:\temp\somefile.txt"))
{
  mc.doSomething();
}

using(MyClass mc = new MyClass(@"c:\temp\somefile.txt"))
{
  mc.doSomething();
}
