实现接口IDisposable的示例

想使用using(...), 如:

using (Getter process = new Getter())
{
         //...
}

就必须给类实现接口IDisposable

public sealed class Getter: IDisposable
    {
        #region Dispose

        private bool disposed;

        ~Getter()
        {
            Dispose(false);
        }

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

        private void Dispose(bool disposing)
        {
            if (!disposed)
            {
                if (disposing)
                {
                    //这里处理一些需要手动dispose的
                    //this.conn.Close();
                    //this.conn.Dispose();
                }
            }
            disposed = true;
        }

        #endregion
}
