Force Download File in ASP.NET

This is example how to force current HTTP Context Response to download file.

Before that, you need to set path / folder in your web application to store file that you just created or pre set the file to download.

In ASP.NET this is the way to set path. Since we can use tiddler("~") symbol to referring to the root with virtual path set from IIS.

  string pathFile = Server.MapPath(Request.ApplicationPath);  

Force download method :

   
  string pathFile = Server.MapPath(Request.ApplicationPath);  
  Response.AddHeader("Content-Type", "application/octet-stream");  
  Response.AddHeader("Content-Transfer-Encoding", "Binary");  
  Response.AddHeader("Content-disposition", "attachment; filename=\"" + yourfilename + ".csv\"");  
  Response.WriteFile(pathFile + yourfilename + ".csv");  
  Response.End();
