Add another window!

{

{

}
This. richtextbox1.text = sb. tostring ();
}
Public void SaveFile ()

Finally, it is worth mentioning that you can quickly create a menu item and drag menustrip to the window in the toolbar, and then select the key in the upper right corner of menustrip.

A standard menu set! Delete unnecessary items by editing items!
