c# - 如何删除WPF中ListView中显示的特定文本？

我已阅读此主题：
how to delete a specific text / message showed in a ListView ?

它在winform中工作正常（我已经测试过！），但是在WPF中却无法正常工作。

我想在listview1中查找firstnametxt的文本并将其与Firstname Column项目进行比较，如果为true，则删除该项目（包含该项目的行）

但是我不知道如何在WPF中处理此问题。

我的部分代码是这样的：

XAML：

<ListView Name="listView1 HorizontalAlignment="Left" VerticalAlignment="Top" />
    <ListView.View>
        <GridView>
            <GridViewColumn Header="FirstName" DisplayMemberBinding="{Binding Path=FirstName}"  />
            <GridViewColumn Header="LastName" DisplayMemberBinding="{Binding Path=LastName}" />
        </GridView>
    </ListView.View>
</ListView>
<TextBox Name="firstnametxt" Height="27" HorizontalAlignment="Left" Margin="271,20,0,0"  VerticalAlignment="Top" Width="181" />
<Button Content="Add" Height="38" HorizontalAlignment="Left" Margin="310,242,0,0" Name="button1" VerticalAlignment="Top" Width="74" Click="button1_Click" />
<Button Content="Find" Height="38" HorizontalAlignment="Left" Name="button2" VerticalAlignment="Top" Width="74" Click="button2_Click" />

（C＃）后面的代码：

public class Familiy
{
    public Familiy(string firstname, string lastname)
    {
        this.FirstName = firstname;
        this.LastName = lastname;
    }
    private string firstname;

    public string FirstName
    {
        get { return firstname; }
        set { firstname = value; }
    }
    private string lastname;
    public string LastName
    {
        get { return lastname; }
        set { lastname = value; }
    }
}


private void button1_Click(object sender, RoutedEventArgs e)
{
    ///////////////////////////
}

最佳答案

您将需要更改ListBox ItemSsource，无论它是ItemList，List还是其他集合，此示例使用“家庭列表”。

public partial class MainWindow : Window
{
    List<Familiy> familiys = new List<Familiy>();
    public MainWindow()
    {
        InitializeComponent();


        familiys.Add( new Familiy("FirstName1", "LastName1"));
        familiys.Add(new Familiy("FirstName2", "LastName2"));
        familiys.Add(new Familiy("FirstName3", "LastName3"));
        familiys.Add(new Familiy("FirstName4", "LastName4"));
        listView1.ItemsSource = familiys;

    }
    private void button1_Click(object sender, RoutedEventArgs e)
    {
        familiys.Remove(familiys.Find(delegate(Familiy f) { return f.FirstName == firstnametxt.Text; }));
        listView1.ItemsSource = "";
        listView1.ItemsSource = familiys;
    }
}
