Hello

i have a problem disposing class in Dictionary

this is my code

  private Dictionary<string, MyProcessor> Processors = new Dictionary<string, MyProcessor>();

        private void button1_Click(object sender, EventArgs e)
        {
            if (!Processors.ContainsKey(textBox1.Text))
            {
                Processors.Add(textBox1.Text, new MyProcessor());
            }

        }

        private void button2_Click(object sender, EventArgs e)
        {
            MyProcessor currnt_processor = Processors[textBox1.Text];
            Processors.Remove(textBox2.Text);
            currnt_processor.Dispose();
            currnt_processor = null;
            GC.Collect(); 
        }








  public class MyProcessor: IDisposable
    {

       private bool isDisposed = false;

       string x = "";

        public MyProcessor()
        {
            for (int i = 0; i < 20000; i++)
            {
            //this line only to increase the memory usage to know if the class is dispose or not
                x = x + "gggggggggggg";    

            }
            this.Dispose();
            GC.SuppressFinalize(this); 
        }

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

        public   void Dispose(bool disposing)
        {
            if (!this.isDisposed)
            {
                isDisposed = true;
                this.Dispose();
            }
        }

        ~MyProcessor()      
        {
            Dispose(false);
        }


    }

i use "ANTS Memory Profiler" to monitor heap memory

the disposing work only when i remove all keys from dictionary

how can i destroy the class from heap memory ?

thanks in advance
