Question

我尝试将我的对象绑定到ListView并且这不起作用，这个对象是从另一个继承的，所以我的怀疑是maby我尝试另一种方式或者我错过了一些东西。这就是我的全部内容：

此对象代表WiresharkFile，我尝试支持多种格式，因此每个格式文件都具有以下属性：

文件名
包数
发送的数据包（我的应用程序也使用Pcap.Net发送此数据包）
持续时间
速度

进度（百分比）

公共抽象类WiresharkFile { protected string _fileName; protected int _packets; protected int _packetsSent; protected string _duration; protected double _speed; protected int _progress;

public string FIleName
{
    get { return _fileName; }
    set { _fileName = value; }
}

public int Packets
{
    get { return _packets; }
    set { _packets = value; }
}

public int PacketsSent
{
    get { return _packetsSent; }
    set { _packetsSent = value; }
}

public string Duration
{
    get { return _duration; }
    set { _duration = value; }
}

public double Speed
{
    get { return _speed; }
    set { _speed = value; }
}

public int Progress
{
    get { return _progress; }
    set { _progress = value; }
}

}

这是我的列表视图：

<ListView ItemsSource="{Binding wiresharkFiles}" >
                    <ListView.View>
                        <GridView ColumnHeaderContainerStyle="{StaticResource ListViewHeaderStyle}">
                            <!-- file name column -->
                            <GridViewColumn Width="485" Header="File name" DisplayMemberBinding="{Binding FileName}" />

                            <!-- speed column -->
                            <GridViewColumn x:Name="SpeedCell"  Width="130" Header="Speed" CellTemplate="{StaticResource MyDataTemplate2}" />

                            <!-- duration column -->
                            <GridViewColumn Width="100" Header="Duration" DisplayMemberBinding="{Binding Duration}" />

                            <!-- packets column -->
                            <GridViewColumn Width="100" Header="Packets" DisplayMemberBinding="{Binding Packets, StringFormat={}{0:#,0}}" />

                            <!-- packet sent -->
                            <GridViewColumn Width="100" Header="Packets sent" DisplayMemberBinding="{Binding PacketsSent, StringFormat={}{0:#,0}}" />

                            <!-- progress column -->
                            <GridViewColumn x:Name="ProgressCell"  Width="60" Header="Progress" CellTemplate="{StaticResource MyDataTemplate}" />
                        </GridView>
                    </ListView.View>
</ListView>

我的Collection包含所有这些对象：

声明：

ObservableCollection<WiresharkFile> wiresharkFiles;

在委托人之后：

wiresharkFiles = new ObservableCollection<WiresharkFile>();
this.DataContext = this;

现在从我的主要内容中创建新对象：

WiresharkFile wiresharkFile = new Libpcap("file name");  
wiresharkFile.ReadFileDetails(); // this read the file and count how many packet contain, duration...
wiresharkFiles.Add(wiresharkFile);

此Libpcap继承自WiresharkFile：

public class Libpcap : WiresharkFile...

所以在这一点之后我的abject在Collection内，但我仍然无法在ListView内看到这一点。我也试着看看try-catch如果扔掉除外但没什么。

你可以尝试

wiresharkFiles = new ObservableCollection<WiresharkFile>();
//this.DataContext = this
this.DataContext = wiresharkFiles;

将我的对象继承绑定到ListView
