C#同时使用2 sqldatareader？

using (SqlConnection connection = new SqlConnection(connectionString))
{
    connection.Open();

    SqlCommand command1 = new SqlCommand("SELECT * FROM Table1", connection);
    SqlDataReader reader1 = command1.ExecuteReader(CommandBehavior.SequentialAccess);

    while (reader1.Read())
    {
        // 读取数据
    }

    reader1.Close();

    SqlCommand command2 = new SqlCommand("SELECT * FROM Table2", connection);
    SqlDataReader reader2 = command2.ExecuteReader(CommandBehavior.SequentialAccess);

    while (reader2.Read())
    {
        // 读取数据
    }

    reader2.Close();
}
