如何将DataRow绑定到TextBlock？

<TextBlock x:Name="txtData" />

DataRow row = // 获取要绑定的DataRow对象
txtData.DataContext = row;

<TextBlock x:Name="txtData" Text="{Binding Path=ColumnName}" />

<Window x:Class="MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="450" Width="800">
    <Grid>
        <TextBlock x:Name="txtData" Text="{Binding Path=ColumnName}" />
    </Grid>
</Window>

using System.Data;
using System.Windows;

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();

        // 模拟获取DataRow对象
        DataTable table = new DataTable();
        table.Columns.Add("ColumnName");
        DataRow row = table.NewRow();
        row["ColumnName"] = "Hello World";

        // 将DataRow绑定到TextBlock
        txtData.DataContext = row;
    }
}
