How to delete file after download with ASP.NET MVC?

Question

I want to delete a file immediately after download, how do I do it? I\'ve tried to subclass FilePathResult and override the WriteFile method where

Answer 1

overriding the OnResultExecuted method is probably the correct solution.. This method runs after the response is written.

public class DeleteFileAttribute : ActionFilterAttribute 
{ 
    public override void OnResultExecuted(ResultExecutedContext filterContext) 
    { 
        filterContext.HttpContext.Response.Flush();
        // Delete file 
    } 
} 

Action code:

[DeleteFileAttribute]
public FileContentResult GetFile(int id)
{
   //your action code
}
