請廣大網友幫忙把編程語言給轉換一下
        public string float_TO_string(float fl)
        {
            byte[] a = BitConverter.GetBytes(fl);
            return a[0].ToString("X2") + a[1].ToString("X2") + a[2].ToString("X2") + a[3].ToString("X2");
        }
        public string float_TO_string(double dl)
        {
            byte[] a = BitConverter.GetBytes(dl);
            return a[0].ToString("X2") + a[1].ToString("X2") + a[2].ToString("X2") + a[3].ToString("X2")+ a[4].ToString("X2") + a[5].ToString("X2") + a[6].ToString("X2") + a[7].ToString("X2");
        }


        public float string_TO_float(string f1)
        {
            byte[] a = new byte[4];
            a[0] = Convert.ToByte(f1.Substring(0, 2));
            a[1] = Convert.ToByte(f1.Substring(2, 2));
            a[2] = Convert.ToByte(f1.Substring(4, 2));
            a[3] = Convert.ToByte(f1.Substring(6, 2));
            return BitConverter.ToSingle(a, 0);
        }
        public double string_TO_double(string d1)
        {
            byte[] a = new byte[8];
            a[0] = Convert.ToByte(d1.Substring(0, 2));
            a[1] = Convert.ToByte(d1.Substring(2, 2));
            a[2] = Convert.ToByte(d1.Substring(4, 2));
            a[3] = Convert.ToByte(d1.Substring(6, 2));
            a[4] = Convert.ToByte(d1.Substring(8, 2));
            a[5] = Convert.ToByte(d1.Substring(10, 2));
            a[6] = Convert.ToByte(d1.Substring(12, 2));
            a[7] = Convert.ToByte(d1.Substring(14, 2));
            return BitConverter.ToDouble(a, 0);
        }

看上去就是十六進制的字符串與單雙精浮點數的互相轉換，既然你會C++應該可以按功能自己寫一個

“42F6E979”<=>1.23456E+2
和
“405EDD2F1A9FBE77”<=>1.23456E+2

就是這么個東西
