Explicit type-casting of pointer

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:

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:

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!!

I would suggest using BitConverter.ToSingle to convert bytes to a float, and BitConverter.GetBytes to convert a float to bytes.

Depending on the architecture of the sender and receiver (little versus big Endian), you may have to consider byte ordering.

In general, c# (or any managed .NET language) does not have pointers.
(Yes, there's unsafe and IntPtr but that is not necessary to accomplish what you've described.)

The way to do this kind of thing in c# is to use the class System.BitConverter.
So to convert a byte[] into a float is:

class Program
{
  static void Main(string[] args)
  {
    byte[] test = { 25, 4, 158, 63 };
    float p = BitConverter.ToSingle(test, 0);
    Console.WriteLine(p);
  }
}

Going the other way, from float to byte[], you would use BitConverter.GetBytes(value);

You can't cast an array to a pointer (not even a fixed-size array). But you can take the address of the 0th item of the array, and then attempt to cast that:

fixed (float* p = (float*)&test[0])
{

}

But that turns out to be explicitly forbidden: "The right hand side of a fixed statement assignment may not be a cast expression".
So there's not much choice, you'd have to do something like this:

fixed (byte* temp = data)
{
    float* p = (float*)temp;
}

There was the alternative of not using unsafe code (not directly anyway, BitConverter.ToSingle is implemented using unsafe code itself) in this case, so this is just for completeness really.

You are using the boolean type false for a number of your parameters, but the ducumentation[^] defines these as ref object types. Try changing your code.

The problem with many of these MSWord methods is that they have many parameters and it not easy to know which combinations are valid. I would suggest simplifying the HitHighlight method call and just specify the text to find, as that is the only required parameter. Set all others to Type.Missing. If that works as expected then reintroduce the other parameters, possibly one at a time.

There are warnings in the documentation that some parameters "may not be available", e.g. HanjaPhoneticHangul is available only if you have support for Korean languages. This may mean that it must be set to Type.Missing and not true or false. The documentation is not clear about this.

C# file access

classy_dog7-Mar-13 1:52

In a C# 2008 windows application, I planning on locating files that I need to find by utilizing the following code:

var RFiles = from path in Directory.EnumerateFiles(filesaveLocation, "*.*", 
SearchOption.AllDirectories) 
  let extension = Path.GetExtension(path) 
  where extension == ".pdf" || extension == ".xlsx" || extension == ".xls" 
  select path;

However once I find each selected file, I need to know the exact location of where each specified file was located. I need to be able to store the exact directory structure location in a sql server 2008 r2 database.

Basically the code statement would be similar to tell me exactly where each seelcted file is located at.

Thus can you me in code and/or explain to me how to accomplish my goal?

In this case, you can switch to use the DirectoryInfo class to do this:

DirectoryInfo filesaveDir = new DirectoryInfo(filesaveLocation);
var RFiles = from fi in filesaveDir.EnumerateFiles("*.*", SearchOption.AllDirectories)
  let extension = fi.Extension 
  where extension == ".pdf" || extension == ".xlsx" || extension == ".xls" 
  select fi.FullName;

You'd need to go through the GridFS documentation; it's not a generic C# subject, and most members will not recognize it. FWIW, there's an example on SO[^].
