浮点数与十六进制数如何互相转换

1、C#中浮点变16进制

float F = 27.251F;
            string s1 = BitConverter.ToString(BitConverter.GetBytes(F));
2、 C#中16进制转浮点 
            string s = "8D03DA41";
            byte[] arr = new byte[s.Length / 2];
            for(int i=0;i            {
                arr[i] = Convert.ToByte(s.Substring(i * 2, 2), 16);
            }
            float f1 = BitConverter.ToSingle(arr, 0);
            MessageBox.Show(f1.ToString());
