body: <p>I'm new to web-developing and I'm trying to read a csv file and create a report in Word.I use webform. Code below is my to load file. records is IEnumerable.</p>
  
  <pre><code>        if (System.IO.Path.GetExtension(FileUploader.PostedFile.FileName).Equals(".csv"))
          {
              CsvReader csv = new CsvReader(File.OpenText(FileUploader.PostedFile.FileName));
              records = csv.GetRecords&lt;T&gt;().ToList();
          }

  <p>How can I save "IEnumerable" records throughout the page lifecycle? records is empty on PostBack and I don't want to save it in ViewState. 
  Thanks</p>
