WPF - 使用XML作为datagrid数据源进行binding

1.xml文件 VMInfo.xml

<?xml version="1.0" encoding="utf-8"?>
<MachineInfo>
  <machine name="cosapx2">
    <OS>32</OS>
    <IE>Win7</IE>
    <OFFICE>2013</OFFICE>
  </machine>
  <machine name="cosapxqa5">
    <OS>64</OS>
    <IE>Win8</IE>
    <OFFICE>2013 std.</OFFICE>
  </machine>
</MachineInfo>

2.Xmal中加载xml数据

<Window.Resources>
        <XmlDataProvider x:Key="vminfo" Source="VMInfo.xml" XPath="/MachineInfo/machine"/>
</Window.Resources>

3.Xmal设置binding

<DataGrid Name="VMInfo" <span style="color:#ff0000;">DataContext="{Binding Source={StaticResource vminfo}}" ItemsSource="{Binding XPath=/MachineInfo/machine}"</span> AutoGenerateColumns="False">
<DataGrid.Columns>
    <DataGridTextColumn Header="Machine Name" Binding="{Binding XPath=@name}"/>
    <DataGridTextColumn Header="OS Version" Binding="{Binding XPath=OS}"/>
    <DataGridTextColumn Header="IE Version" Binding="{Binding XPath=IE}"/>
    <DataGridTextColumn Header="Office Version" Binding="{Binding XPath=OFFICE}"/>
    </DataGrid.Columns>
</DataGrid>

加@表示xml元素的属性，不加则表示子级元素

4.运行结果



========== 华丽丽的分割线=========

由于上面的邦定方法不太好对datagrid query,今天又学了一个稍微好点的方法：先把xml读到dataset里，再邦定给datagrid。想要query，对数据源dt进行query就行了。

Xmal设置：

<DataGrid Name="VMInfo" ItemsSource="{Binding}" AutoGenerateColumns="False">
<DataGrid.Columns>
    <DataGridTextColumn Header="Machine Name" Binding="{Binding XName}"/>
    <DataGridTextColumn Header="OS Version" Binding="{Binding OS}"/>
    <DataGridTextColumn Header="IE Version" Binding="{Binding IE}"/>
    <DataGridTextColumn Header="Office Version" Binding="{Binding OFFICE}"/>
    </DataGrid.Columns>
</DataGrid>

后台设置数据源：

System.Data.DataSet ds = new System.Data.DataSet();
ds.ReadXml("");
System.Data.DataTable dt = ds.Tables[0]; 
this.VMInfo.Itemssource = dt.DefaultView;
