如何将datatable设置为WPF datagrid C#？

我是c#的新手，所以放松点

基本上，我构建了一个数据表（我已经验证了它不是空的），但它似乎没有显示在我的wpf数据网格中。。。我在这里使用了这个示例并应用了它：

我的数据网格仍然是空白的

你们觉得这个例子好吗

这是我的密码：

XACML：

<Window x:Class="WpfApplication1.TickerSearch"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="TickerSearch" Height="468" Width="907">
<Grid Background="#E6000000" Name="_grid">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="244*" />
        <ColumnDefinition Width="37*" />
    </Grid.ColumnDefinitions>
    <TextBox Height="34" HorizontalAlignment="Left" Margin="26,15,0,0" Name="txtSearchTker" VerticalAlignment="Top" Width="225" Grid.ColumnSpan="2" />
    <Button Content="Search" Height="32" HorizontalAlignment="Left" Margin="76,160,0,0" Name="btnSearch" VerticalAlignment="Top" Width="124" Click="btnSearch_Click" />
    <ListBox Height="114" HorizontalAlignment="Left" Margin="26,224,0,0" Name="lstResults" VerticalAlignment="Top" Width="225" Visibility="Hidden" Grid.ColumnSpan="2" Background="#FFFFB000" />
    <Button Content="Select" Height="32" HorizontalAlignment="Left" Margin="76,366,0,0" Name="btnSelect" VerticalAlignment="Top" Width="124" Visibility="Hidden" />
    <Label Content="Start Date: " Height="25" HorizontalAlignment="Left" Margin="22,65,0,0" Name="label1" VerticalAlignment="Top" Width="71" Background="#00FFB000" FontFamily="Georgia" Foreground="#FFFFB000" />

    <DatePicker Height="22" HorizontalAlignment="Left" Margin="93,65,0,0" Name="dateFrom" VerticalAlignment="Top" Width="138" />
    <DatePicker Height="22" HorizontalAlignment="Left" Margin="93,94,0,0" Name="toDate" VerticalAlignment="Top" Width="138" />

    <CheckBox Content="CheckBox" Height="17" HorizontalAlignment="Left" Margin="93,127,0,0" Name="chkBoxToday" VerticalAlignment="Top" Width="15" />
    <DataGrid AutoGenerateColumns="False" Height="315" HorizontalAlignment="Left" Margin="285,68,0,0" x:Name="_dataGrid" VerticalAlignment="Top" Width="468" ItemsSource="{Binding Path=.}" Background="#C6F7F700"></DataGrid>
</Grid>

在没有看到任何代码的情况下，我建议最重要的两点是：

• 使用myGrid.DataContext=myDS.Tables[0]设置DataContext
• 让XAML数据网格包含ItemsSource属性：

  将其更改为
  ItemsSource=“{Binding}”
  
  另外，将
  AutoGenerateColumns
  设置为true。（或明确指定列）
  显示一些代码，以便我们可以帮助…添加到原始帖子中
              _ds = new DataSet();
              DataTable table = yahooFinance.lookupSymbol();
              _ds.Tables.Add(table);
              _grid.DataContext = _ds.Tables[0];
