In this article I will explain with an example, how to download XML file from Folder (Directory) in ASP.Net MVC Razor.
Following is the XML file named Customers consisting of records of Customers stored in the project folder.
<?xml version="1.0" standalone="yes"?>
The Controller consists of following Action method.
Action method for handling GET operation
Inside this Action method, following properties set are the Response class.
1. ContentType – It informs the Browser about the file type. In this case it is XML.
2. Content-Disposition – It is a response header indicating, the download file is an attachment and allows setting the file name.
Once the Response properties are set, the XML file contents are read as string and then stored in a variable.
Finally, the variable i.e. XML file contents are sent to the Client Browser as string using the Content function.
Note: The Content function sends the data to the Response similar to Response.Write function.
public class HomeController : Controller
// GET: Home
public ActionResult Index()
//Set the Response properties.
Response.Buffer = true;
Response.Charset = "";
Response.ContentType = "application/xml";
Response.AddHeader("content-disposition", "attachment; filename=Customers.xml");
//Read the XML file contents as String.
string xml = System.IO.File.ReadAllText(Server.MapPath("~/XML/Customers.xml"));
There is no programming required inside the View and hence this section is skipped.
