c#接收c语言的数据源，转换为byte数组 然后转换成结构体，做过的帮忙看看 谢谢！

[SomethingJack]

c的结构体如下:

typedef struct tagSta_Record
{
	//char time_stamp[23];
	float av_speed[ARS_MAX_MEASURELINE_NUM][ARS_MAX_LANE_NUM][ARS_MAX_VEHICLETYPE_NUM];
	uint8 vloume[ARS_MAX_MEASURELINE_NUM][ARS_MAX_LANE_NUM][ARS_MAX_VEHICLETYPE_NUM];
	float occuancy[ARS_MAX_MEASURELINE_NUM][ARS_MAX_LANE_NUM][ARS_MAX_VEHICLETYPE_NUM];
	//float headway[ARS_MAX_MEASURELINE_NUM][ARS_MAX_LANE_NUM][ARS_MAX_VEHICLETYPE_NUM];
	//float _85_speed[ARS_MAX_MEASURELINE_NUM][ARS_MAX_LANE_NUM][ARS_MAX_VEHICLETYPE_NUM];
	//BYTE is_offline[][][];
}STA_RECORD;

我写的转换DEMO ，不太懂，所以发上来大家帮忙看看，没有得到想要的结果

static void Main(string[] args)
        {
//这是接收到的数据源
            string str = "CA CB CC CD 01 82 60 03 00 00 00 00 00 00 80 3F 00 00 00 40 00 00 80 3F 00 00 00 40 00 00 40 40 00 00 00 40 00 00 40 40 00 00 80 40 00 00 40 40 00 00 80 40 00 00 A0 40 00 00 80 40 00 00 A0 40 00 00 C0 40 00 00 A0 40 00 00 C0 40 00 00 E0 40 00 00 C0 40 00 00 E0 40 00 00 00 41 00 00 E0 40 00 00 00 41 00 00 10 41 00 00 80 3F 00 00 00 40 00 00 40 40 00 00 00 40 00 00 40 40 00 00 80 40 00 00 40 40 00 00 80 40 00 00 A0 40 00 00 80 40 00 00 A0 40 00 00 C0 40 00 00 A0 40 00 00 C0 40 00 00 E0 40 00 00 C0 40 00 00 E0 40 00 00 00 41 00 00 E0 40 00 00 00 41 00 00 10 41 00 00 00 41 00 00 10 41 00 00 20 41 00 00 00 40 00 00 40 40 00 00 80 40 00 00 40 40 00 00 80 40 00 00 A0 40 00 00 80 40 00 00 A0 40 00 00 C0 40 00 00 A0 40 00 00 C0 40 00 00 E0 40 00 00 C0 40 00 00 E0 40 00 00 00 41 00 00 E0 40 00 00 00 41 00 00 10 41 00 00 00 41 00 00 10 41 00 00 20 41 00 00 10 41 00 00 20 41 00 00 30 41 00 00 40 40 00 00 80 40 00 00 A0 40 00 00 80 40 00 00 A0 40 00 00 C0 40 00 00 A0 40 00 00 C0 40 00 00 E0 40 00 00 C0 40 00 00 E0 40 00 00 00 41 00 00 E0 40 00 00 00 41 00 00 10 41 00 00 00 41 00 00 10 41 00 00 20 41 00 00 10 41 00 00 20 41 00 00 30 41 00 00 20 41 00 00 30 41 00 00 40 41 00 01 02 01 02 03 02 03 04 03 04 05 04 05 06 05 06 07 06 07 08 07 08 09 01 02 03 02 03 04 03 04 05 04 05 06 05 06 07 06 07 08 07 08 09 08 09 0A 02 03 04 03 04 05 04 05 06 05 06 07 06 07 08 07 08 09 08 09 0A 09 0A 0B 03 04 05 04 05 06 05 06 07 06 07 08 07 08 09 08 09 0A 09 0A 0B 0A 0B 0C 00 00 00 00 00 00 80 3F 00 00 00 40 00 00 80 3F 00 00 00 40 00 00 40 40 00 00 00 40 00 00 40 40 00 00 80 40 00 00 40 40 00 00 80 40 00 00 A0 40 00 00 80 40 00 00 A0 40 00 00 C0 40 00 00 A0 40 00 00 C0 40 00 00 E0 40 00 00 C0 40 00 00 E0 40 00 00 00 41 00 00 E0 40 00 00 00 41 00 00 10 41 00 00 80 3F 00 00 00 40 00 00 40 40 00 00 00 40 00 00 40 40 00 00 80 40 00 00 40 40 00 00 80 40 00 00 A0 40 00 00 80 40 00 00 A0 40 00 00 C0 40 00 00 A0 40 00 00 C0 40 00 00 E0 40 00 00 C0 40 00 00 E0 40 00 00 00 41 00 00 E0 40 00 00 00 41 00 00 10 41 00 00 00 41 00 00 10 41 00 00 20 41 00 00 00 40 00 00 40 40 00 00 80 40 00 00 40 40 00 00 80 40 00 00 A0 40 00 00 80 40 00 00 A0 40 00 00 C0 40 00 00 A0 40 00 00 C0 40 00 00 E0 40 00 00 C0 40 00 00 E0 40 00 00 00 41 00 00 E0 40 00 00 00 41 00 00 10 41 00 00 00 41 00 00 10 41 00 00 20 41 00 00 10 41 00 00 20 41 00 00 30 41 00 00 40 40 00 00 80 40 00 00 A0 40 00 00 80 40 00 00 A0 40 00 00 C0 40 00 00 A0 40 00 00 C0 40 00 00 E0 40 00 00 C0 40 00 00 E0 40 00 00 00 41 00 00 E0 40 00 00 00 41 00 00 10 41 00 00 00 41 00 00 10 41 00 00 20 41 00 00 10 41 00 00 20 41 00 00 30 41 00 00 20 41 00 00 30 41 00 00 40 41 00 00";

思路是对的，但是一开始就错了 string str = "CA" byte[] bytes = System.Text.Encoding.ASCII.GetBytes(str); 这个转出来不是你想要的结果 要这样转 str.Split(' ').Select(x => byte.Parse(x, NumberStyles.HexNumber)).ToArray();

[忘丿殇]

byte[] 数组反序列化为结构体~~~应该是可以的

[本拉灯]

StructDemo 这是啥玩意思。

这是c#的结构体.

 public struct StructDemo 
    {
        //[ARS_MAX_MEASURELINE_NUM][ARS_MAX_LANE_NUM][ARS_MAX_VEHICLETYPE_NUM] new int[] { 1, 3, 5 }, new int[] { 2 }, new int[] { 4, 8 }
        //char time_stamp[23];
        float[, ,] av_speeddata;
        uint[, ,] vloume;
        float[, ,] occuancy;
        // float[, ,] av_speeddata = new float[4, 8, 2];
        //uint vloume[ARS_MAX_MEASURELINE_NUM][ARS_MAX_LANE_NUM][ARS_MAX_VEHICLETYPE_NUM];
        //float occuancy[ARS_MAX_MEASURELINE_NUM][ARS_MAX_LANE_NUM][ARS_MAX_VEHICLETYPE_NUM];
        //float headway[ARS_MAX_MEASURELINE_NUM][ARS_MAX_LANE_NUM][ARS_MAX_VEHICLETYPE_NUM];
        //float _85_speed[ARS_MAX_MEASURELINE_NUM][ARS_MAX_LANE_NUM][ARS_MAX_VEHICLETYPE_NUM];
        //BYTE is_offline[][][];

        public StructDemo (float[, ,] _av_speeddata, uint[, ,] _vloume, float[, ,] _occuancy)
        {
            this.av_speeddata = _av_speeddata;
            this.vloume = _vloume;
            this.occuancy = _occuancy;
        }
    }

希望得到就是 一个结构体 里面已经有了想要的参数 实际结构体也是一个类嘛 下位机发过来的

[Poopaye]

无语，楼主你自己查查uint8是什么

[SomethingJack]

不是 那个是我写错了 都是float类型的

引用 6 楼 shingoscar 的回复:

跟C语言那边对应

[Poopaye]

你是说c语言那边都是float？ 好吧，那接收到的数据究竟是什么类型的？

[本拉灯]

float av_speed[ARS_MAX_MEASURELINE_NUM][ARS_MAX_LANE_NUM][ARS_MAX_VEHICLETYPE_NUM]; uint8 vloume[ARS_MAX_MEASURELINE_NUM][ARS_MAX_LANE_NUM][ARS_MAX_VEHICLETYPE_NUM]; float occuancy[ARS_MAX_MEASURELINE_NUM][ARS_MAX_LANE_NUM][ARS_MAX_VEHICLETYPE_NUM]; 这不都有长度了么 在C#里面一个float就是4个字节 ， ARS_MAX_MEASURELINE_NUM 这里面的参数就是这个数组的定长，你可以算一下呗，就能得出每个数组的总长了，

[xuzuning]

你给出的结构有误！
