关于C＃WPF：C＃WPF – Listview绑定无法正常工作

C# WPF - Listview Binding not working

我一直试图在WPF中创建一个窗口，并将ListView绑定到对象列表，但我无法使列表中的对象显示在ListView中。

以下是窗口的XAML：

<Window x:Class="WpfApplication.window_ManageInstruments"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

Title="window_ManageInstruments" Height="400" Width="600" WindowStartupLocation="CenterOwner">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="100" />
<RowDefinition />
</Grid.RowDefinitions>
<ListView Grid.Row="1" Margin="5" Name="listInstruments" ItemsSource="{Binding InstrumentList}">
<ListView.View>
<GridView>
<GridViewColumn Width="120" Header="Symbol" DisplayMemberBinding="{Binding Field1}"/>
<GridViewColumn Width="200" Header="Description" DisplayMemberBinding="{Binding Field2}"/>
<GridViewColumn Width="120" Header="Last Stats" DisplayMemberBinding="{Binding Field3}"/>
<GridViewColumn Width="100" Header="Margin" DisplayMemberBinding="{Binding Field4}"/>
</GridView>
</ListView.View>
</ListView>

<Label HorizontalAlignment="Left" Margin="10,10,0,0" Name="label1" Width="120" Height="25" VerticalAlignment="Top">Symbol</Label>
<Label HorizontalAlignment="Left" Margin="10,40,0,0" Name="label2" Width="120" Height="25">Description</Label>
<TextBox Height="25" Margin="150,10,0,0" Name="txtSymbol" VerticalAlignment="Top" HorizontalAlignment="Left" Width="120" />
<TextBox Margin="150,40,0,0" Name="txtDescription" HorizontalAlignment="Left" Width="120" Height="25" />
<Button Height="23" HorizontalAlignment="Right" Margin="0,12,133,0" Name="btn_AddInstrument" VerticalAlignment="Top" Width="75">Add</Button>
</Grid>

InstrumentList.Add(new TestClass { Field1 ="A", Field2 ="B", Field3 ="C", Field4 ="D" });
InstrumentList.Add(new TestClass { Field1 ="E", Field2 ="F", Field3 ="G", Field4 ="H" });
InitializeComponent();
}
}

public class TestClass {
public string Field1 { get; set; }
public string Field2 { get; set; }
public string Field3 { get; set; }
public string Field4 { get; set; }
}
}

我不知道这里是否缺少任何重要的配置，所以任何帮助都将非常感谢。

提前谢谢。

我认为你的工具列表应该是一个属性。把它改成

private ObservableCollection _instrumentList = new ObservableCollection();
public ObservableCollection InstrumentList{
get{ return _instrumentList;}
}
