请教一下如下C++算法如何转化为C#的

Question

Unsigned char c1[4];
Float fdbm;c1[3]=ca;
c1[2]=cb;
c1[1]=cc;
c1[0]=cd;fdbm=*(float *)(c1);
c++c#算法

Answer 1

byte[] c1 = {0xcd, 0xcc, 0xcb, 0xca};
float fdbm = BitConverter.ToSingle(c1, 0);

Answer 2

byte[] c1 = new byte[4];
            float fdbm = 0;
            unsafe
            {
                fixed(byte* lpc1 = &c1[0])
                    fdbm = *(float*)lpc1;
            }
