QuestionExplicit type-casting of pointer Pin

Hello experts,

I'm quite new to dotnet programming and so on, so perhaps my question is very easy to answer.
I'm sending data from a µC to PC over USB. This is byte wise and when I want so send a float, I did it like in this C++ test code and it worked:

C#
int _tmain(int argc, _TCHAR* argv[])
{
    char test[4] = {25,4,158,63};
    float *blubb = (float*)&test[0];
    printf("%f",*blubb);
    return 0;
}


Now I want to do the same in C# and it doesn't work. Here is my attempt:

C#
namespace csharpfloattest
{
    class Program
    {
        unsafe static void Main(string[] args)
        {


                byte[] test = { 25, 4, 158, 63 };
                fixed (float* p = (float*)test)
                {
                    Console.WriteLine(*p);
                }
         }
    }
}


Compiler gives out this error:
Cannot convert type 'byte[]' to 'float*'


Perhaps someone can give me an advice? Smile | :)

Thanks for your help!!
Florian
