Use the form that I add an my project

Question

I added a form from another solution.(With right on my solution and clicked add existing item and then select a resent form with name "newForm.cs").Then this form with own objects added to my project.But I can't use this form in my code.For example I want to show this form.But it isn't in my solution as a class that I use:"newForm frm = new newForm". How do I can add this form that I can use it as a class. I hope I have made the correct question. Thanks very much.

Answer 1

If you want to set this as startup form then Edit that from the program.cs file

Moreover might be you need to change the namespace of the added form, please check that.

If you want to start this form from other form then create an object of this form and show the instace of this form.

Formname frm1 = new Formname();
frm1.show();
