解决问题的是使用 ToArray() 而不是 GetBuffer()。干杯

using (var workbook = new XLWorkbook())
{
    var worksheet = workbook.AddWorksheet("name");
    worksheet.Row(1).Cell(i + 1).SetValue("test");
    worksheet.Row(k + 2).Cell(column.Order + 1).SetValue("test value");
    using (var memoryStream = new MemoryStream())
    {
        workbook.SaveAs(memoryStream);
        memoryStream.Position = 0;
        return memoryStream.ToArray();
    }
}
