实现效果:
知识运用:
KeyEventArgs类的KeyData属性
public Keys KeyData {get;} //获取KeyDown或KeyUp事件的键数据
控件的Focus方法
public bool Focus() // 为控件设置输入焦点
实现代码:
private void txtUser_KeyDown(object sender, KeyEventArgs e) { if (e.KeyData == Keys.Enter) txtPwd.Focus(); } private void txtPwd_KeyDown(object sender, KeyEventArgs e) { if (e.KeyData == Keys.Enter) btLogin.Focus(); }
