Equality of Form and Form1

Question

Hi, I have a collection of MDI forms, where there are different objects (Form1,Form2 etc). Is there any fast way how to compare whather selected form (using FOR cycle for iterating through form collection) is Form1,Form2..? Thank you!

Answer 1

  foreach(Form f in AllForms)
  {
      if(f is From1)
         return true;
  }

Answer 2

Sounds like a straightforward thing to do, what is the actual problem you are facing?

Have you tried a regular compare?

foreach(Form f in AllForms) {
  if(f == myForm1)
    return true;
}

Use f == myForm1 if you already have a single instance of Form1 named myForm1 that you are comparing against or f is Form1 if you are looking for "any" Form1, without already having one somewhere.
