title: C# How to copy the content of excel as you see (for example: date time as you see is 12/31/2018, excel content is a number like 43465)
body: <p>I am having a problem with parsing excel content to datetime type.</p>
  
  <p>In my country, there are just two cultureinfo to use: "vi-VN" (dd/MM/yyyy) and "us-US" (MM/dd/yyyy).</p>
  
  <p>For some cases I test, both DateTime.Parse with cultureinfo above throwing error "String is not recognized as a valid datetime".</p>
  
  <p>I want to use DateTime.ParseExact instead of above approach. In order to do this, I must get a string like "12/31/2018". But when I use Epplus, it reads the content of the cell as a number 43465. This way, I cannot parse use DateTime.ParseExact.</p>
  
  <p>Any here know how to read the excel as you see on the screen ?</p>
  
  <p>Thank you.</p>
