Defining a DType struct in C# for use in np.fromfile

[yolothedino]

How would I transpose the below code chunk to C#? I'm trying to convert the following python code to be used in C#. The point of this function is to parse a binary file's data into a collection of defined objects.

dtype = np.dtype([
	("reading_1", np.float64),
	("reading_2", np.float32),
	("reading_3", np.float64)
# and so on
])
...
# file is a binary file of the structured data defined above
datachunks = np.fromfile(file, dtype)
# do things with arrays of reading_1, reading_2, reading_3 from datachunks

My roadblock right now is that I do not know how to write the 'dtype' segment in C#. I have tried to declare a struct of my own and using it as a parameter for np.fromfile, which I know will not work because np.fromfile requires a Dtype.

[StructLayout(LayoutKind.Sequential)]
public struct ReadingData
{
    public double reading_1;
    public float reading_2;
    public double reading_1;
}
...
NDArray datachunks = np.fromfile(filename, ReadingData);
// syntax error as ReadingData is not a dtype

I can't find any examples on writing a dtype struct in SciSharp's C# Numpy, so I am stumped.

I am pretty sure what you are trying to do is not supported, at least the way you are doing it. I would need a minimal python snippet that creates a small file and then reads it back in, you know, just a few numbers in each reading. From that I can try to come up with an equivalent in Numpy.NET.
