MVC file download

Question

Hi Team,

 

When I try to download file using MVC controller I am always getting blank Excel file. Please let me know how to download file with the data. My requirement is to download or view the file from some path. 

 

I have followed below Article but it is also downloading blank file. Any security issue?
