Execute code in form1 from form2 without creating new instance

Question

Am trying to execute a command in form1 from form2 without creating a new instance. Is that possible

Yes it's possible though the accessibility of the method in Form1 will need to be either public or internal so that it can be accessed by other forms or classes in the application. Subject to that all you need is a reference to your Form1 instance. There are many ways to get this but here's one which doesn't involve changes to your existing code: // from Form2 Form1 f1 = Application.OpenForms[Form1] as Form1; if (f1 != null) { f1.SomeMethod(); }
