Dispose

Question

Hello All, i'm confusing about the purpose of Dispose for example, i have 2 forms and on Form1 i have a button. on click event of button i instantiate Form2 private void button1_Click(object sender, System.EventArgs e) { Form2 objFrm2 = new Form2(); objFrm2.Show(); } Then, i click the button twice. So now i have 2 objects of Form2. on closed event of Form2, i use Dispose method private void Form2_Closed(object sender, System.EventArgs e) { this.Dispose(); } If i close Form2 once, then now i only have 1 object of Form2, right? But, with a tool i use, it's said that i still have 2 objects of Form2. How to really remove object of Form2 from memory allocation? If i use GC.Collect(), the tool also said it's not recommended to call GC.Collect by our own. It's better to let the GC work on his own. What i want is, to remove the objects i dont need anymore and i want so GC remove it from memory.
