无法使用线程返回DataTable

using System;
using System.Data;
using System.Threading;

public class Program
{
    public delegate void DataTableCallback(DataTable dataTable);

    public static void Main()
    {
        // 创建一个线程，并传递委托作为参数
        Thread thread = new Thread(new ParameterizedThreadStart(DoWork));
        thread.Start(new DataTableCallback(ProcessDataTable));
        
        // 主线程继续执行其他操作
        
        // 等待子线程执行完成
        thread.Join();
    }

    public static void DoWork(object callback)
    {
        // 模拟耗时操作，例如从数据库中查询数据并存储在DataTable中
        DataTable dataTable = new DataTable();
        dataTable.Columns.Add("ID", typeof(int));
        dataTable.Columns.Add("Name", typeof(string));
        dataTable.Rows.Add(1, "John");
        dataTable.Rows.Add(2, "Jane");
        
        // 调用委托并传递DataTable对象
        ((DataTableCallback)callback)(dataTable);
    }

    public static void ProcessDataTable(DataTable dataTable)
    {
        // 在主线程中处理DataTable对象
        Console.WriteLine("Received DataTable:");
        foreach (DataRow row in dataTable.Rows)
        {
            Console.WriteLine(row["ID"] + " - " + row["Name"]);
        }
    }
}
