概述：本文主要介绍WPF绑定各种数据源之xml数据源，希望对大家有帮助。

　　WPF绑定各种数据源之xml数据源，此时的XML源写在界面了，当然也可以独立成文件。

<Window.Resources>

        <Con:BackgroundConverter x:Key="BackgroundConverter"/>

        <XmlDataProvider x:Key="myPerson3">

            <x:XData>

                <PersonF xmlns="">

                    <person Name="Person1">

                        <ID>1</ID>

                        <Name>XiaoA</Name>

                        <Age>49</Age>

                    </person>

                    <person Name="Person2">

                        <ID>2</ID>

                        <Name>XiaoB</Name>

                        <Age>29</Age>

                    </person>

                    <person Name="Person3">

                        <ID>3</ID>

                        <Name>XiaoC</Name>

                        <Age>103</Age>

                    </person>

                    <person Name="Person4">

                        <ID>4</ID>

                        <Name>XiaoD</Name>

                        <Age>59</Age>

                    </person>

                </PersonF>

            </x:XData>

        </XmlDataProvider>

    </Window.Resources>

　　下面是绑定的代码。此时需要注意，原来用Path改成了XPath，因为这是XML源，并且ItemsSource 改成 ItemsSource="{Binding Source=
{StaticResource myPerson3},XPath=/PersonF/person}"

<ListView ;Height="262" Margin="0,32,56,0"

ItemsSource="{Binding Source={StaticResource myPerson3},
XPath=/PersonF/person}"
VerticalAlignment="Top"  Name="listView3"
HorizontalAlignment="Right" Width="310">

       <ListView.View>

           <GridView>

               <GridViewColumn Header="编号"

DisplayMemberBinding="{Binding XPath=ID}" Width="100" />

<GridViewColumn Header="姓名"

DisplayMemberBinding="{Binding XPath=Name}" Width="100"/>

               <GridViewColumn Header="年龄" Width="100">

                   <GridViewColumn.CellTemplate>

                       <DataTemplate>

                           <TextBlock Grid.Column="1" Text="{Binding XPath=Age}"
Foreground="{Binding XPath=Age,
Converter={StaticResource BackgroundConverter}}"/>

                       </DataTemplate>

                   </GridViewColumn.CellTemplate>

               </GridViewColumn>

           </GridView>

       </ListView.View>

   </ListView>

　　下面是值转换

public class BackgroundConverter : IValueConverter

    {

        #region IValueConverter Members

        public object Convert(object value, Type targetType, object parameter,
System.Globalization.CultureInfo culture)

        {

            Color color = new Color();

            int num = int.Parse(value.ToString());

            if (num > 100)

                color = Colors.Yellow;

            else if (num < 50)

                color = Colors.LightGreen;

            else

                color = Colors.LightPink;

            return new SolidColorBrush(color);

        }

        public object ConvertBack(object value, Type targetType,
object parameter, System.Globalization.CultureInfo culture)

        {

            throw new NotImplementedException();

        }

        #endregion

    }
