- public ActionResult Import(HttpPostedFileBase currencyConversionsFile)
- {
- string filename = "CurrencyConversion Upload_" + DateTime.Now.ToString("dd-MM-yyyy") + ".csv";
- string folderPath = Server.MapPath("~/Files/");
- string filePath = Server.MapPath("~/Files/" + filename);
- currencyConversionsFile.SaveAs(filePath);
- string[] csvData = System.IO.File.ReadAllLines(filePath);
- //the later code isn't show here
- }
我知道将httppostedfilebase转换为String数组的常用方法,它首先将文件存储在服务器中,然后从服务器读取数据.无论如何直接从httppostedfilebase获取字符串数组而不将文件存储到服务器中？
解决方法
那么你可以像Stream一样逐行读取你的文件：
- List<string> csvData = new List<string>();
- using (System.IO.StreamReader reader = new System.IO.StreamReader(currencyConversionsFile.InputStream))
- {
- while (!reader.EndOfStream)
- {
- csvData.Add(reader.ReadLine());
- }
- }
