Document,PdfWriter and Paragraph are unrecognized. What namespace to be added? I am a little concerned there is not a single using statement in any example I can find Is it not needed here?

I think you have at least 3 disposable objects Yes, using statements are good. If this is a production app with more than, say ONE person using it, this may cause problems The FileSteamResult will close the stream for you.

See this answer stackoverflow. You must specify : Response. Machinegon Machinegon 1, 1 1 gold badge 26 26 silver badges 43 43 bronze badges.

Anything after? MapPath maps to a physical file location. And what does passing the PDF name as a parameter to that page do? The combination of that name and querystring does not look like a physical path to a pdf file, which is what you are trying to return. If you want to return through action methods of the controller. If the content you want to transfer is stored within a disk file, you can use the FilePathResult object.

The class that does this is the action invoker, a system component that governs the whole process of executing a request and creating the response for the browser. You can envisage the ActionResult class as being a way to encapsulate the particular type of response that you want to send to the browser.

The response certainly comprises the actual data but it also includes the content type, the status code, and any cookies and headers that you intend to send. All of these things are aspects of the response you might want to control through a tailor-made ActionResult class. The mechanics of action result classes is best understood by taking a tour of a couple of system-provided action result classes. As you can see, all it does is to set the status code and description of the HTTP response object.

As the code listing shows, this class is just a wrapper that does nothing more than set the status code:. To create, for example, a HttpNotFoundResult custom type, all you have to do is to duplicate the previous code and just set the proper status code; 0x in this case.

A slightly more sophisticated example is the FileResult class. This class supplies a public property, the ContentType property that contains the type of the data being written to the output stream. In the implementation of ExecuteResult , the class simply downloads the content of a given file. FileResult is a base class, and in fact it exposes an abstract method-the WriteFile method-through which derived class can specify how to download and where and how to get the bits.

It is interesting to note the role of the FileDownloadName property. Instead, it gets and sets the content-disposition header. The header gives a name for the file that can be used to save the file locally on the client, and the browser would use to display the default name within a file-download dialog box. The class FilePathResult builds on top of FileResult and just adds the ability to download any type of file.

This class defines a FileName property and uses the native TransmitFile method of the Response object to download the file. With this information to hand, we can conclude that the action result object is simply a way to encapsulate all the tasks you need to accomplish in particular situations such as:.

Suppose that at some point you decide to expose a given feature of your application through another URL but still need to support the old URL. This feature, however, is lacking in ASP. Anyway, it would be a good exercise to have a look at a possible implementation that follows closely that of RedirectResult in ASP. Having this class available you can easily move your features around without impacting the SEO level of your application.

A common developer requirement is to return binary data from a request. Among the built-in action result objects, you can certainly find one that helps you to work with your particular type of binary data. Net: Download. Hi tanws8, Change the return type of your method to ActionResult. Octet, "test. Hi dharmendr, The code you provided downloads the PDF document directly.
