如何从文本文件向DataGrid传递​值？C# WPF

public class FileData
{
    public string Column1 { get; set; }
    public string Column2 { get; set; }
}

using System.Collections.Generic;
using System.IO;
using System.Windows;
using System.Windows.Controls;

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

            // 读取文本文件
            string filePath = "path_to_your_file.txt";
            List<FileData> data = ReadFile(filePath);

            // 绑定数据到DataGrid
            dataGrid.ItemsSource = data;
        }

        private List<FileData> ReadFile(string filePath)
        {
            List<FileData> data = new List<FileData>();

            using (StreamReader reader = new StreamReader(filePath))
            {
                string line;
                while ((line = reader.ReadLine()) != null)
                {
                    // 假设每行数据用逗号分隔
                    string[] parts = line.Split(',');
                    if (parts.Length == 2)
                    {
                        data.Add(new FileData { Column1 = parts[0], Column2 = parts[1] });
                    }
                }
            }

            return data;
        }
    }
}
