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.\r\n\r\n\r\n```\r\ndtype = np.dtype([\r\n\t(\"reading_1\", np.float64),\r\n\t(\"reading_2\", np.float32),\r\n\t(\"reading_3\", np.float64)\r\n# and so on\r\n])\r\n...\r\n# file is a binary file of the structured data defined above\r\ndatachunks = np.fromfile(file, dtype)\r\n# do things with arrays of reading_1, reading_2, reading_3 from datachunks\r\n```\r\n\r\nMy 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.\r\n\r\n```\r\n[StructLayout(LayoutKind.Sequential)]\r\npublic struct ReadingData\r\n{\r\n    public double reading_1;\r\n    public float reading_2;\r\n    public double reading_1;\r\n}\r\n...\r\nNDArray datachunks = np.fromfile(filename, ReadingData);\r\n// syntax error as ReadingData is not a dtype\r\n```\r\n\r\nI can't find any examples on writing a dtype struct in SciSharp's C# Numpy, so I am stumped.","author":{"url":"https://github.com/yolothedino","@type":"Person","name":"yolothedino"},"datePublished":"2024-12-10T09:00:32.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/131/Numpy.NET/issues/131"}
