[C#] ServiceStack.Redis如何批量的pop数据？

要安全的批量pop数据，有两个办法：

1、用事务（不用事务的话可能导致重复读。ServiceStack的pipeline是没有自带事务的。）

2、执行lua脚本

我这里提供用事务的实现方法：

public static string ReadLine(RedisNativeClient cln)
{
	MethodInfo mi = cln.GetType().GetMethod("ReadLine", BindingFlags.NonPublic | BindingFlags.Instance);
	string ret = (string)mi.Invoke(cln, new object[] { });
	return ret;
}

public static List<string> BatchDequeue(RedisNativeClient cln, string listID, int max_count)
{
	List<string> ret = new List<string>();

	var uListId = Encoding.UTF8.GetBytes(listID);
	var pipeline = cln.CreatePipelineCommand();
	pipeline.WriteCommand(Commands.Multi);
	pipeline.WriteCommand(Commands.LRange, uListId, Encoding.UTF8.GetBytes("0"), Encoding.UTF8.GetBytes((max_count - 1).ToString()));
	pipeline.WriteCommand(Commands.LTrim, uListId, Encoding.UTF8.GetBytes(max_count.ToString()), Encoding.UTF8.GetBytes("-1"));
	pipeline.WriteCommand(Commands.Exec);
	pipeline.Flush();

	var a1 = ReadLine(cln);		//忽略Multi的OK
	var a2 = ReadLine(cln);		//忽略LRANGE的QUEUED
	var a3 = ReadLine(cln);		//忽略LTRIM的QUEUED
	var a4 = ReadLine(cln);		//忽略*2
	var b = cln.ReceiveMessages();
	foreach (var item in b)
	{
		string ss = Encoding.UTF8.GetString(item);
		ret.Add(ss);
	}
	ReadLine(cln);		//忽略EXEC的OK

	return ret;
}
