问题描述

你好

我创建一个Windows Phone应用程序。我有一个文本框我想把文件从xml文件中删除。我有一个错误，无法转换systemCollectionGenric en String如何才能解决这个问题

这是我的文本框定义到XAML。

< textbox x：name =Nomwidth =371margin =0,496,0,0height =90verticalalignment =热门xmlns：x =＃unknown>





和我的xml文件

XDocument loadedData = XDocument.Load("XML.xml");

var data = from query in loadedData.Descendants("Chart")
           select new Person
           {
               FirstName = (string)query.Element("title"),
               LastName = (string)query.Element("Graph"),
               Age = (int)query.Element("StrokeThickness")
           };
Nom.Text = data;

推荐答案

你好，





它应该在查询结果的Value属性中使用，而不是将查询字符串值转换为整数

Hello,


It should be used in the Value property of the query result, instead regarding the query string value is converted to an integer

InitializeComponent();
XDocument loadedData = XDocument.Load("XML.xml");
 
var data = from query in loadedData.Descendants("Chart")
           select new Person
           {
               FirstName = query.Element("title").Value,
               LastName = query.Element("Graph").Value,
               Age = Int.Parse(query.Element("StrokeThickness").Value)
           };
Nom.Text = data;

再见。

Bye.
