C# - 在一个方法中，我怎样才能有 2 个参数是一个？

Question

In my project I have forms and user controls. I have this important method for changing the mouse cursor.

public static void Cursor_Hand(Form frm)
{
      foreach (Control control in frm.Controls)
      {
            if (control.Cursor == Cursors.Hand)
            {
                 control.Cursor = Program.SystemHandCursor;
            }
      }
 }

However, it only works if I submit a Form as an argument, I need it to accept Form and Usercontrol.

If possible, I also need both to have the same name, so I don't have to check with IF which argument was sent.

Ignore the wrong syntax, but I wanted something like:

public static void Cursor_Hand(Form frm || UserControl frm)

Answer 1

Both of those types inherit from Control :

public static void Cursor_Hand(Control frm)
