1、创建类：MulitBooleanConverter

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Windows.Data;namespace ScreenLock{    class MulitBooleanConverter : IValueConverter    {        #region IValueConverter Members        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)        {            int serviceParameter = int.Parse(parameter.ToString());            bool isOnservice = (bool)value;            bool result = false;            switch (serviceParameter)            {                case 0:                    result = true && isOnservice;                    break;                case 1:                    result = !isOnservice;                    break;            }            return result;        }        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)        {            int serviceParameter = int.Parse(parameter.ToString());            bool isOnservice = (bool)value;            bool result = false;            switch (serviceParameter)            {                case 0:                    result = true && isOnservice;                    break;                case 1:                    result = false && isOnservice;                    break;            }            return value;        }        #endregion    }}

2、界面RadioButton

<Window x:Class="ScreenLock.RadioButton"        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"        Title="RadioButton" Height="300" Width="300"        xmlns:local="clr-namespace:ScreenLock"        >    <Window.Resources>        <local:MulitBooleanConverter x:Key="boolConverter"></local:MulitBooleanConverter>        <Style x:Key="HorizontalRadioButtonListStyle" TargetType="ListBox">            <Style.Resources>                <Style TargetType="ListBoxItem">                    <Setter Property="Template">                        <Setter.Value>                            <ControlTemplate TargetType="ListBoxItem">                                <Grid Margin="2">                                    <Grid.ColumnDefinitions>                                        <ColumnDefinition Width="Auto" />                                        <ColumnDefinition />                                    </Grid.ColumnDefinitions>                                    <RadioButton IsChecked="{Binding IsSelected,                                  RelativeSource={RelativeSource TemplatedParent},                                  Mode=TwoWay}" />                                    <ContentPresenter Grid.Column="1" Margin="2,0,0,0" />                                </Grid>                            </ControlTemplate>                        </Setter.Value>                    </Setter>                </Style>            </Style.Resources>            <Setter Property="ItemsPanel">                <Setter.Value>                    <ItemsPanelTemplate>                        <WrapPanel Orientation="Horizontal"  />                    </ItemsPanelTemplate>                </Setter.Value>            </Setter>            <Setter Property="BorderThickness" Value="0" />            <Setter Property="Background" Value="Transparent" />        </Style>    </Window.Resources>    <Grid>        <ListBox Style="{StaticResource HorizontalRadioButtonListStyle}" x:Name="list1" SelectionChanged="list1_SelectionChanged">            <ListBox.Items>                <ListBoxItem  IsSelected="{Binding xxx,Converter={StaticResource boolConverter},ConverterParameter=0}" Content="在线" ></ListBoxItem>                <ListBoxItem IsSelected="{Binding xxx,Converter={StaticResource boolConverter},ConverterParameter=1}" Content="离线"></ListBoxItem>                <ListBoxItem IsSelected="{Binding xxx,Converter={StaticResource boolConverter},ConverterParameter=0}" Content="离线llll"></ListBoxItem>            </ListBox.Items>        </ListBox>    </Grid></Window>

3、后台选中事件

  private void list1_SelectionChanged(object sender, SelectionChangedEventArgs e)        {            MessageBox.Show(((ListBoxItem)list1.SelectedItem).Content.ToString());        }
