如何使用HDF.PInvoke制作具有复合数据类型的数据集？

Question

我想制作一个数据类型不同的数据集，例如，一个长字符串数组。我参考了https://support.hdfgroup.org/ftp/HDF5/examples/misc-examples/sample-programs/strings.c并编写了一个简单的测试程序，但是当我打开结果文件时，它是空的。

我想知道我做错了什么。我正在使用HDF.PInvoke.1.10.5.2和C＃。

using HDF.PInvoke;
using System.Globalization;
using System.IO;

using System.Runtime.InteropServices;


namespace WindowsFormsApp3
{
    public unsafe struct struct_TR
    {
        public long[] arr_currentLong;
        public string[] arr_currentString;

        public struct_TR(byte size_currentTime, byte size_currentPrice)
        {
            arr_currentLong = new long[size_currentTime];
            arr_currentString = new string[size_currentPrice];
        }
    }


    public unsafe partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();

            string currentPath = Path.GetDirectoryName(Application.ExecutablePath);     
            Directory.SetCurrentDirectory(currentPath);                                 


            struct_TR struct01 = new struct_TR(2, 2);

            struct01.arr_currentLong[0] = 10;
            struct01.arr_currentLong[1] = 11;

            struct01.arr_currentString[0] = "Hello";
            struct01.arr_currentString[1] = "Hi";

            long file_id = H5F.create(@"file.h5", H5F.ACC_TRUNC, H5P.DEFAULT, H5P.DEFAULT);

            long myDataSpace = H5S.create(H5S.class_t.SCALAR);


            IntPtr pnt = Marshal.AllocHGlobal(Marshal.SizeOf(struct01));

            long strtype = H5T.copy(H5T.C_S1);

            long myH5MessageType = H5T.create(H5T.class_t.COMPOUND, pnt);
            H5T.insert(myH5MessageType, "long", pnt, H5T.NATIVE_LONG);
            H5T.insert(myH5MessageType, "string", pnt, strtype);

            long myDataSet = H5D.create(file_id, "/myCustomData", myH5MessageType, myDataSpace);

            long write_id = H5D.write(myDataSet, myDataSpace, H5S.ALL, H5S.ALL, H5P.DEFAULT, pnt);


            long status = H5D.close(myDataSet);
            long status2 = H5S.close(myDataSpace);
            long status3 = H5F.close(file_id);

        }
    }
}
