c# - Save excel file or worksheet as csv using NPOI

Question

How to save an excel file as csv using NPOI? I have tried below.

//corrupt csv/excel
                using (var csvStream = new FileStream(csvPath, FileMode.Create, FileAccess.Write))
                {
                    workBook.Write(csvStream);
                }
  //empty file
            using (FileStream fs = new FileStream(excelPath, FileMode.Open, FileAccess.Read))
            {
                using (var csvStream = new FileStream(csvPath, FileMode.Create, FileAccess.Write))
                {
                    fs.Position = 0;
                    fs.CopyToAsync(csvStream);
                }
            }
