                                            <!--<Label VerticalOptions="FillAndExpand" Text="{Binding Cijena, StringFormat='{0} KM'}"></Label>-->

我在使用C＃代码中的标记项时遇到问题，我尝试清洁，重建，重新启动PC，重新安装软件包，更改表格Build Action，甚至使用C＃方法查找命名的布局和/或条目，但没有运气。我总是得到**名称kolicinaIn或layNameLast在当前上下文错误中不存在。 **

因此无法访问布局LayNameLast或其任何成员，但是我必须严格按此顺序进行操作，而且我必须能够访问它。
