Forcing a Save As dialog box from an ASP.NET Web page

We can write below line of code to achieve:-

Response.Clear();  
Response.AppendHeader("content-disposition", "attachment; filename=document1.doc");  
Response.ContentType = "text/plain";  
Response.WriteFile(Server.MapPath("document1.doc"));  
Response.Flush();  
Response.End();

Above code once executed will ask a dialog box to save or open.
