WPF ListView/GridView 绑定

我正在尝试制作一个简单的 VS 2017 扩展，它获取一个对象并显示它。我有数据返回并在文本框中显示 json，所以我知道数据正确返回。但由于某种原因，gv 仅显示单词“id”两次，因为它们是数据集中的两条记录。我已经尝试了很多事情，但我却失去了方向。另外，文档似乎到处都是。

我相信这里至少可能存在两个问题......

1) XAML“绑定”

2）将数据绑定或添加到LV？

任何对此的帮助将不胜感激！

XAML

<UserControl x:Class="DoWork.AllWorkVSControl"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
             Background="{DynamicResource VsBrush.Window}"
             Foreground="{DynamicResource VsBrush.WindowText}"
             mc:Ignorable="d"
             d:DesignHeight="300" d:DesignWidth="300"
             Name="MyToolWindow">
    <Grid>
        <StackPanel Orientation="Vertical">
            <TextBlock Margin="10" HorizontalAlignment="Center">AllWorkVS</TextBlock>
            <Button Content="Click me!" Click="button1_Click" Width="120" Height="80" Name="button1"/>
            <TextBox Height="200" TextWrapping="Wrap" Name="txtJson"/>
            <ListView x:Name="LvIssues">
                <ListView.View>
                    <GridView>
                        <GridView.Columns>
                            <GridViewColumn Width="Auto" Header="Id"  DisplayMemberBinding="{Binding Source='Id'}"></GridViewColumn>
                        </GridView.Columns>
                    </GridView>
                </ListView.View>
            </ListView>
        </StackPanel>
    </Grid>
</UserControl>

C#

public class People
{
    public string Id { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

public partial class AllWorkVSControl : UserControl
{

    public AllWorkVSControl()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, RoutedEventArgs e)
    {
        var t = Issues.GetPeopleById("2");
        PopulateListView();
        MessageBox.Show(t);
    }

    private void PopulateListView()
    {
        var l = GetPeople();
        txtJson.Text = JsonConvert.SerializeObject(l);

        foreach (var p in l)
        {
            LvIssues.Items.Add(p);
        }
    }
}

您需要设置ListView.ItemsSource。

private void PopulateListView()
{
    var l = GetPeople();
    txtJson.Text = JsonConvert.SerializeObject(l);

    LvIssues.ItemsSource= l;
}

<ListView x:Name="LvIssues">
            <ListView.View>
                <GridView>
                    <GridView.Columns>
                        <GridViewColumn Width="Auto" Header="Id"  DisplayMemberBinding="{Binding Id}"></GridViewColumn>
                    </GridView.Columns>
                </GridView>
            </ListView.View>
        </ListView>
