Question

我仍在学习WPF，C＃和xml文件。我有具有现有内容的xml文件。我想做的是：

在datagrid中显示xml文件内容
当xml文件是显示在datagrid中，用户可以编辑内容
用户编辑完内容，将新数据写入相同的xml文件中但我坚持第一步。

我想显示类似这样的内容（仅示例，不是真实数据）：

文件名= Eqpt ID
文件位置=装备操作
名称=二进制代码
姓氏= bin描述，
电话号码=垃圾桶质量

以此类推。

但是问题是，当我运行应用程序时，它像这样出来这是我尝试过的：

string sampleXMLFile = FilePath.XmlBinCode;
DataSet dataSet = new DataSet();
dataSet.ReadXml(sampleXMLFile);
DataView dataView = new DataView(dataSet.Tables[0]);
dataGrid_ConfigurableRejectBinCode.ItemsSource = dataView;

这是我的xml文件的预览：

这是我的XAML的预览：

 <DockPanel Background="White">
    <Button Content="Load File" Click="LoadXmlFile_Click" DockPanel.Dock="Top"/>
    <DataGrid x:Name="dataGrid_ConfigurableRejectBinCode"
              DockPanel.Dock="Bottom"
              CanUserAddRows="True"
              CanUserDeleteRows="True"
              CanUserReorderColumns="False"
              CanUserResizeColumns="False"
              CanUserResizeRows="False"
              CanUserSortColumns="False">
        <DataGrid.Columns>
            <!--<DataGridTextColumn Header="Bin Code" Binding="{Binding BinCode}"/>
            <DataGridTextColumn Header="Bin Description" Binding="{Binding Path=Element[BinDescription].Value}"/>
            <DataGridTextColumn Header="Bin Quality" Binding="{Binding Path=Element[BinQuality].Value}"/>
            <DataGridTextColumn Header="Pick" Binding="{Binding Path=Element[Pick].Value}"/>
            <DataGridTextColumn Header="Vision Station" Binding="{Binding Path=Element[VisionStation].Value}"/>
            <DataGridTextColumn Header="Vision IO" Binding="{Binding Path=Element[VisionIO].Value}"/>-->
        </DataGrid.Columns>
    </DataGrid>
</DockPanel>

如何像我上面想要的那样显示xml数据？请原谅我的语言，因为英语不是我的母语。请帮助我，谢谢你

Answer 1

我已经找到了显示它的方法，这就是我的方法

make类并绑定所有要在XAML控件中显示的细节。这是XAML

<Grid Background="White">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="*"/>
        <RowDefinition Height="Auto"/>
        <RowDefinition Height="Auto"/>
    </Grid.RowDefinitions>
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*"/>
        <ColumnDefinition Width="*"/>
    </Grid.ColumnDefinitions>
    <TextBlock Grid.Row="0" Grid.Column="0" Text="Eqpt ID"/>
    <TextBlock Grid.Row="1" Grid.Column="0" Text="Equip Opn"/>

    <TextBox Grid.Row="0" Grid.Column="1" IsReadOnly="True" Text="{Binding EqptID}"/>
    <TextBox Grid.Row="1" Grid.Column="1" IsReadOnly="True" Text="{Binding EquipOpn}"/>

    <DataGrid Grid.Row="2" Grid.Column="0" Grid.ColumnSpan="2" x:Name="DataGrid_BinDefinition" 
              AutoGenerateColumns="False"
              CanUserAddRows="False"
              CanUserDeleteRows="False"
              CanUserReorderColumns="False"
              CanUserResizeColumns="False"
              CanUserResizeRows="False"
              CanUserSortColumns="False"
              HorizontalContentAlignment="Center"
              ItemsSource="{Binding BinDefinition}">
        <DataGrid.Columns>
            <DataGridTextColumn Header="Bin Code" Binding="{Binding BinCode}"/>
            <DataGridTextColumn Header="Bin Description" Binding="{Binding BinDescription}"/>
            <DataGridTextColumn Header="Bin Quality" Binding="{Binding BinQuality}"/>
            <DataGridCheckBoxColumn Header="Pick" Binding="{Binding Pick}"/>
            <mahApps:DataGridNumericUpDownColumn Header="Vision Station" Binding="{Binding VisionStation}" Maximum="3" Minimum="1"/>
            <mahApps:DataGridNumericUpDownColumn Header="Vision IO" Binding="{Binding VisionIO}" Maximum="32" Minimum="1"/>
        </DataGrid.Columns>
    </DataGrid>

    <Button Grid.Row="3" Grid.Column="0" x:Name="ButtonAddRow" Content="Add Row" Click="ButtonAddRow_Click"/>
    <Button Grid.Row="3" Grid.Column="1" x:Name="ButtonDeleteRow" Content="Delete Row" Click="ButtonDeleteRow_Click"/>
    <Button Grid.Row="4" Grid.Column="0" Grid.ColumnSpan="2" x:Name="ButtonSaveFile" Content="Save File" Click="ButtonSaveFile_Click"/>
</Grid>

然后是绑定控件的类

 [Serializable]
public partial class XmlBinDefinitionModel : ViewModelBase
{
    [XmlElement("EqptID")]
    private string eqptID;
    public string EqptID
    {
        get { return eqptID; }
        set
        {
            if (eqptID != value)
            {
                eqptID = value;
                RaisePropertyChanged(nameof(EqptID));
            }
        }
    }

    [XmlElement("EquipOpn")]
    private string equipOpn;
    public string EquipOpn
    {
        get { return equipOpn; }
        set
        {
            if (equipOpn != value)
            {
                equipOpn = value;
                RaisePropertyChanged(nameof(EquipOpn));
            }
        }
    }

    private List<BinDefinitionModel> binDefinition;
    public List<BinDefinitionModel> BinDefinition
    {
        get { return binDefinition; }
        set
        {
            if (binDefinition != value)
            {
                binDefinition = value;
                RaisePropertyChanged(nameof(BinDefinition));
            }
        }
    }
}//end public partial class XmlBinDefinitionModel 

public partial class BinDefinitionModel : ViewModelBase
{
    [XmlElement("BinCode")]
    private string binCode;
    public string BinCode
    {
        get { return binCode; }
        set
        {
            if (binCode != value)
            {
                binCode = value;
                RaisePropertyChanged(nameof(BinCode));
            }
        }
    }

    [XmlElement("BinDescription")]
    private string binDescription;
    public string BinDescription
    {
        get { return binDescription; }
        set
        {
            if (binDescription != value)
            {
                binDescription = value;
                RaisePropertyChanged(nameof(BinDescription));
            }
        }
    }

    [XmlElement("BinQuality")]
    private string binQuality;
    public string BinQuality
    {
        get { return binQuality; }
        set
        {
            if (binQuality != value)
            {
                binQuality = value;
                RaisePropertyChanged(nameof(BinQuality));
            }
        }
    }

    [XmlElement("Pick")]
    private string pick;
    public string Pick
    {
        get { return pick; }
        set
        {
            if (pick != value)
            {
                pick = value;
                RaisePropertyChanged(nameof(Pick));
            }
        }
    }

    [XmlElement("VisionStation")]
    private string visionStation;
    public string VisionStation
    {
        get { return visionStation; }
        set
        {
            if (visionStation != value)
            {
                visionStation = value;
                RaisePropertyChanged(nameof(VisionStation));
            }
        }
    }

    [XmlElement("VisionIO")]
    private string visionIO;
    public string VisionIO
    {
        get { return visionIO; }
        set
        {
            if (visionIO != value)
            {
                visionIO = value;
                RaisePropertyChanged(nameof(VisionIO));
            }
        }
    }
}

然后在代码后面

XmlDocument xmlDocument = new XmlDocument();
            xmlDocument.Load(FilePath.XmlBinCode); //load the file
            xmlBinDefinitionModel.EqptID = xmlDocument.DocumentElement.SelectSingleNode("EqptID").InnerText;
            xmlBinDefinitionModel.EquipOpn = xmlDocument.DocumentElement.SelectSingleNode("EquipOpn").InnerText;
            xmlBinDefinitionModel.BinDefinition = new List<BinDefinitionModel>();
            XmlNodeList binCodeList = xmlDocument.GetElementsByTagName("BinCode");
            XmlNodeList binDescriptionList = xmlDocument.GetElementsByTagName("BinDescription");
            XmlNodeList binQualityList = xmlDocument.GetElementsByTagName("BinQuality");
            XmlNodeList pickList = xmlDocument.GetElementsByTagName("Pick");
            XmlNodeList visionStationList = xmlDocument.GetElementsByTagName("VisionStation");
            XmlNodeList visionIOList = xmlDocument.GetElementsByTagName("VisionIO");
            for (int i = 0; i < binCodeList.Count; i++)
            {
                xmlBinDefinitionModel.BinDefinition.Add(new BinDefinitionModel
                {
                    BinCode = binCodeList[i].InnerText.Remove(0,2),
                    BinDescription = binDescriptionList[i].InnerText,
                    BinQuality = binQualityList[i].InnerText,
                    Pick = pickList[i].InnerText,
                    VisionStation = visionStationList[i].InnerText,
                    VisionIO = visionStationList[i].InnerText
                });
            }
