访问 selectedItem xamarin 表单的属性 [英] access properties of the selectedItem xamarin forms

问题描述

尝试访问列表中的属性{Name}，例如使用 slectedItem.

Trying to access the property{Name} inside a list , using slectedItem ex.

 var SName = e.SelectedItem;

            if (e.SelectedItem == null)
            {
                return;
            }
            await DisplayAlert("Item Selected", SName.ToString(), "Ok");

常用的方法是 var SName = e.SelectedItem.Name;.但是我没有选择访问它.我已经有了 get;set;如果我在提及行上添加一个断点，它会显示我想要显示的 Name 属性和值.有什么建议吗?谢谢

the common way will be just var SName = e.SelectedItem.Name;. However I dont get the option to access it . I already have the get;set; and if I add a breakpoint on the mention line it shows me the Name property and value that I want to display. any suggestion ? Thanks

推荐答案

e.SelectedItem 属于 object 类型 - 您需要先将其转换为适当的类型

e.SelectedItem is of type object - you need to cast it to the appropriate type first

var item = (MyType) e.SelectedItem;
var name = item.Name;
