如何使用 csvhelper 有效地编写包含数千列的 csv 文件？

Question

I am working on measurement software from which results are written to a huge list of lists which I am trying to put into .csv file using csvhelper. Problem is that to keep things fairly readable and I need to create thousands of columns and I don't see any simple and effective way to do it.

How can I create a .csv file which consist, let's say, 2000 columns?

EDIT 1. Sorry for my inaccurate post (it was my first ever made on StackOverflow).

Problem I am trying to solve is to create a .csv file with thousands of columns while using only a couple of lines of code so that a program will be as simple as possible. The main reason why I want to do it that way is to keep file readable by different software for data analysis.

What about adding properties to an ExpandoObject() (perhaps programatically in a loop) and then writing it out like so:

void Main()
{
    var records = new List<dynamic>();

    dynamic record = new ExpandoObject();
    record.Id = 1;
    record.Name = "one";
    records.Add(record);

    using (var writer = new StringWriter())
    using (var csv = new CsvWriter(writer))
    {
        csv.WriteRecords(records);

        writer.ToString().Dump();
    }
}
