Explain how to refactor your code to fix problems after renaming a Button that already had a Click() method.
What will be an ideal response?
Code refactoring is the process of changing a program's internal structure without changing the way the program works. After you change the name of the Button using the Designer, switch to view the code. Right-click the name of the method (e.g., button1_Click()). From the menu that appears, click Rename. When you click Rename, a dialog box opens. Type the new method name-for example, using the button's Name, an underscore, and Click, but not adding the parentheses that appear in the method header. When you finish, click OK. A Preview Changes dialog box will highlight the change. You can confirm the change by clicking Apply.
