C#保存二进制文件到本地，并进行加载

直接写了变量和对应的函数，需要的名词空间自己引用一下

string path = "D:/Works/DEMO/Hands/Assets/StreamingAssets/";
string Leftpath = "D:/Works/DEMO/Hands/Assets/StreamingAssets/LeftHand.bytes";
public static byte[] currentFramesLeft = new byte[3 * sizeof(double)];
//将一个点的二进制文件保存在本地
currentFramesLeft = EncodeLeftToByteArray();//编码点
File.WriteAllBytes(path+"LeftHand.bytes", currentFramesLeft);//保存在本地



public byte[] EncodeLeftToByteArray()//编码点
    {
        int index = 0;

        byte[] pos_x = BitConverter.GetBytes((double)Pos_Left[i].x);
        pos_x.CopyTo(currentFrameLeft, index);
        index += sizeof(double);
        byte[] pos_y = BitConverter.GetBytes((double)Pos_Left[i].y);
        pos_y.CopyTo(currentFrameLeft, index);
        index += sizeof(double);
        byte[] pos_z = BitConverter.GetBytes((double)Pos_Left[i].z);
        pos_z.CopyTo(currentFrameLeft, index);
   
        return currentFrameLeft;
    }

//加载二进制文件并解码、赋值
    IEnumerator Loadlefthandbyte(string path)
    {
        WWW www = new WWW(path);
        yield return www;
        LoadRemoteLeftHand(www.bytes);
    }

    StartCoroutine(Loadlefthandbyte(Leftpath));


    private void LoadRemoteLeftHand(byte[] frame)//解码,赋值
    {
        int index = 0;

        index += sizeof(double);
        
        Hand.Wrist.x = (float)BitConverter.ToDouble(frame, index);
        index += sizeof(double);
        Hand.Wrist.y = (float)BitConverter.ToDouble(frame, index);
        index += sizeof(double);
        Hand.Wrist.z = (float)BitConverter.ToDouble(frame, index);
        L_Wrist[0].transform.position = new Vector3(Hand.Wrist.x, Hand.Wrist.y, Hand.Wrist.z);
    }
