There are two cases where you need to copy a form
1. Within the same project
Right-click the form-Copy, then paste,
Modify the new form's ". cs" and ". Designer.cs "class file name public partial class new form name: Form
Change the form name of the new form
After you cannot copy directly, modify the new form name, which will cause the original form to be modified as well. It may be reported that multiple error messages are specified in the "Resources" parameter
