如何替换.NET Core2.x中的SqlCommand.BeginExecuteReader？

using System;
using System.Data.SqlClient;
using System.Threading.Tasks;

public class Program
{
    public static async Task Main(string[] args)
    {
        string connectionString = "your_connection_string";
        string query = "SELECT * FROM your_table";

        using (SqlConnection connection = new SqlConnection(connectionString))
        {
            await connection.OpenAsync();

            using (SqlCommand command = new SqlCommand(query, connection))
            {
                using (SqlDataReader reader = await command.ExecuteReaderAsync())
                {
                    while (await reader.ReadAsync())
                    {
                        // 处理查询结果
                    }
                }
            }
        }
    }
}
