problem in reading hdf5 file into c#

Dear developers.

I am a newbie in the hdf5 world, but I'm really interested in learning how to work with it.

I'm trying to read a .h5 file into C#.
I have downloaded the HDF5DotNet reference and the required dlls in order to run my Visual Studio application.
I bumped into some difficulties while reading the file, which for the majority of you would be just a simple routine.

I attached a screenshot with the code and the result printed on screen.

As you can see I get a strange result for the variable "Wrap" which should give me the value of the correspondent variable Ls in .h5
Ls is a scalar number with a value of 0.01
The actual value I want to get out is somehow hidden into it, but I was not able to access it.

Does some of you know where I get it wrong?

Thank you so much for your help.
Looking forward to hearing from you.

Best regards.

Mirco,

Output Ls[0], not Wrap. When you write Wrap you're just getting the data type. If you write Ls, you'll probably get something similar.

Hi Mirco,

You might want to use HDF.PInvoke instead of HDF5DotNet. The latter is not being updated anymore, the former one is brand new and closer to the native c-API.
Have a look at GitHub - HDFGroup/HDF.PInvoke: Raw HDF5 Power for .NET and NuGet Gallery | HDF.PInvoke 1.10.6.1

Best regards,
Detlef
