这个类使用a StreamWriter并因此实现IDisposable.

public class Foo : IDisposable
{
    private StreamWriter _Writer;

    public Foo (String path)
    {
        // here happens something along the lines of:
        FileStream fileWrite = File.Open (path, FileMode.OpenOrCreate, FileAccess.Write, FileShare.ReadWrite);
        _Writer = new StreamWriter (fileWrite, new ASCIIEncoding ());
    }

    public void Dispose ()
    {
        Dispose (true);
        GC.SuppressFinalize (this);
    }

    ~Foo()
    {
        Dispose (false);
    }

    protected virtual void Dispose (bool disposing)
    {
        if (_Disposed) {
            return;
        }
        if (disposing) {
            _Writer.Dispose ();
        }
        _Writer = null; …
