How does one dispose of a field

Question

I recently started using code analyzer and OOOO! boy do i have a lot of violations lol. most are of iDisposable i have been doing my research and so far i have managed to dispose of a few. however i think i have exhausted the tiny bit of smarts i got so help anyone.

public partial class Form1 : Form already implements the idisposable method i just don't know in what way i should use it in this case.

   public partial class Form1 : Form 

   {

     private readonly Label CompPany = new Label();

    private readonly SpeechRecognitionEngine _recognizer = 
    new SpeechRecognitionEngine(new System.Globalization.CultureInfo("en- 
    US"));

   }

i need to know how to dispose of this kind of field

Answer 1

A Form already implements IDisposable. All you need to do is override Dispose(bool) and call _recognizer.Dispose() if disposing is true:

public partial class Form1 : Form 
{
    private readonly SpeechRecognitionEngine _recognizer = 
        new SpeechRecognitionEngine(new System.Globalization.CultureInfo("en-US"));

    protected override void Dispose (bool disposing)
    {
        if (disposing)
        {
            _recognizer.Dispose();
        }
        base.Dispose(disposing);
    }
}

By this, whenever the form is disposed, also the created SpeechRecognitionEngine will be disposed.
