是否有一种简单/标准的方法可以从文件读取到列表视图并从列表视图保存到文件？我真的不在乎它是 TXT 文件、XAML 文件还是二进制文件。这不重要，我没有那么多数据。

这是每个列中存储的列和数据

    public class LVData
    {
        public string Name { get; set; }
        public string YoungPic { get; set; }
        public string MediumPic { get; set; }
        public string AdultPic { get; set; }
        public bool SaltWater { get; set; }
        public bool FreshWater { get; set; }
        public bool Grasslands { get; set; }
        public bool Swamp { get; set; }
        public bool TropicalForrest { get; set; }
        public bool Forest { get; set; }
        public bool ForestEdge { get; set; }
        public bool Sand { get; set; }
        public bool Coastal { get; set; }
        public bool RiverBorder { get; set; }
        public bool LakeBorder { get; set; }
        public bool Floodplain { get; set; }
    }

我的列表视图名为 listView1。

和 XAML：

<Window x:Class="DinosaurIsland.PlantDisplay"

这是整个表单/对话框/listview（不管它叫什么）的图片： Listview image http://dinosaur-island.com/wordpress/wp-content/uploads/2013/06/Seding-Plants.jpg

自从拍摄了这个屏幕截图后，我还添加了一个“加载”按钮。

我编写了一个小项目来从 XML 读取数据并将其显示在ListView.

以下是示例 XML 文件

<?xml version="1.0" encoding="utf-8"?>
<Persons>
  <Person>
    <Name>Dave</Name>
    <YoungPic>Picture1</YoungPic>
    <MediumPic>Picture2</MediumPic>
    <AdultPic>Picture3</AdultPic>
    <Terrain>1</Terrain>
  </Person>
  <Person>
    <Name>Rachael</Name>
    <YoungPic>Picture1</YoungPic>
    <MediumPic>Picture2</MediumPic>
    <AdultPic>Picture3</AdultPic>
    <Terrain>2</Terrain>
  </Person>
</Persons>

具有两种方式绑定 ListView 的 XAML 代码

<Window x:Class="lvs.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="400">
    <Grid>
        <ListView ItemsSource="{Binding Path=lsvData, Mode=TwoWay}"   
        Name="listview1" HorizontalAlignment="Left" Margin="0,0,0,63" Width="262">
            <ListView.View>
                <GridView>
                    <GridViewColumn DisplayMemberBinding="{Binding Path=Name}" Header="Name" />
                    <GridViewColumn DisplayMemberBinding="{Binding Path=YoungPic}" Header="Young Pic" />
                    <GridViewColumn DisplayMemberBinding="{Binding Path=MediumPic}" Header="Medium Pic" />
                    <GridViewColumn DisplayMemberBinding="{Binding Path=AdultPic}" Header="Adult Pic" />
                    <GridViewColumn DisplayMemberBinding="{Binding Path=Terrain}" Header="Terrain" />
                </GridView>
            </ListView.View>
        </ListView>
        <Button Content="Load" Height="23" HorizontalAlignment="Left" Margin="62,0,0,12" Name="Load" VerticalAlignment="Bottom" Width="146" Click="button1_Click" />
        <Button Content="Save" Height="23" HorizontalAlignment="Left" Margin="224,0,0,12" Name="Save" VerticalAlignment="Bottom" Width="128" />
    </Grid>
</Window>

以下是 Mainwindow.xaml.cs 的代码

public partial class MainWindow : Window
    {
        private WindowViewModel _wvm;
        public MainWindow()
        {
            InitializeComponent();
            _wvm = new WindowViewModel();
            this.DataContext = _wvm;
        }

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            _wvm.PopulateData();
        }
    }

然后在同一个项目命名空间中添加以下两个类 - Viewmodel 和 lsvData

public class LVData
    {
        public string Name { get; set; }
        public string YoungPic { get; set; }
        public string MediumPic { get; set; }
        public string AdultPic { get; set; }
        public byte Terrain { get; set; }
    }
    public class WindowViewModel : INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler PropertyChanged;
        //called when a property is changed
        protected void RaisePropertyChanged(string PropertyName)
        {
            if (PropertyChanged != null)
            {
                PropertyChanged(this, new PropertyChangedEventArgs(PropertyName));
            }
        }

        private ObservableCollection<LVData> _personList = new ObservableCollection<LVData>();
        public ObservableCollection<LVData> lsvData
        {
            get { return _personList; }
            set { _personList = value; RaisePropertyChanged("lsvData"); }
        }

        public void PopulateDataFromXML()
        {
            XDocument loaded = XDocument.Load(@"c:\documents and settings\bjasti\my documents\visual studio 2010\Projects\lvs\lvs\data.xml");

            var Persons = from x in loaded.Descendants("Person")
                          select new
                          {
                              Name = x.Descendants("Name").First().Value,
                              YoungPic = x.Descendants("YoungPic").First().Value,
                              MediumPic = x.Descendants("MediumPic").First().Value,
                              AdultPic = x.Descendants("AdultPic").First().Value,
                              Terrain = x.Descendants("Terrain").First().Value
                          };
            foreach (var _person in Persons)
            {
                _personList.Add(new LVData { Name = _person.Name, YoungPic = _person.YoungPic, MediumPic = _person.MediumPic, AdultPic = _person.AdultPic, Terrain = Convert.ToByte(_person.Terrain) });
            }

            RaisePropertyChanged("lsvData");
        }

    }

检查此解决方案并让我知道它是否有效
