推荐答案

仅编写方法将无济于事，您必须将其挂接到事件上，并将其作为可接受的事件处理程序提供-这意味着两个参数，对象发送者"和"KeyEventArgs e"-不是一个.

两种方法.
1)在表单设计器中，突出显示要处理偶数的控件，然后在属性"窗口中选择事件"-它是带有闪电的小按钮.双击KeyPress事件，将生成一个处理程序，并提供一个最小方法.
2)在代码查看器中，可能在FormLoad事件中，通过键入控件名称，然后键入".KeyPress"，然后再键入"+ ="和两次Tab键，来添加处理程序.这将创建与上述相同的方法并将其挂接到事件中.

Just writing a method will do nothing, you have to hook it to the event, and supply it as an acceptable eventhandler - which mean two parameters, "object sender" and "KeyEventArgs e" - not one.

Two ways to do it.
1) In the form designer, highlight the control you want to handle the even, and select Events on the Properties window - it''s the little button with a lightning bolt on it. Double click the KeyPress event and a handler will be generated and a minimal method supplied.
2) In the code viewer, probably in the FormLoad event, add a handler by typing your control name followed by ".KeyPress", then "+=" followed by the Tab key twice. This will create the same method as above and hook it into the event.
