Download Files in ASP. NET MVC 3 using Controller Action.
Last week I was conducting a training for one of my clients on ASP. NET MVC 3 features.
They had a file server, hosting various types of reports and were using an ASP. NET Web Form application as a front- end to download the reports on the client machine. Now since they planned on migrating the ASP. NET Web. Forms to ASP. NET MVC, they expected a similar functionality in MVC too.
As most of you working on ASP. NET MVC know, the Views are directly controlled by controller action.
Every action method from the controller class returns an Action. Result. This itself is an abstract class.
We have several classes inherited from it and they are used in specific cases. One of the classes inherited from Action.
Result is File. Result. This class is used to send binary file content to the response. In the following sample, we will see how we can leverage the File. Result action to download files in an ASP. NET MVC Web Application. Step 1: Open VS2. ASP. NET MVC 3 project, name it as .
Step 2: In the project, add a new folder and name it as . Add couple of PDF files in it. Step 3: Right- click on the Models folder and add a new class file, name it as . Add the following classes in it: namespace MVC3. This method reads all files from the .
The File Path on the File Server//2. The content type MIME type//3. The parameter for the file save by the browserreturn File(filename, content. Type.

PDF. The method returns an object of the type . This is the class inherited from File.
Result. File. Path. Result accepts three parameters. The first is the file path of the file which is to be downloaded.
The second is the content type. The third parameter is the Download file name.
This is an optional parameter, but if passed, then the browser will show the download effect. Step 5: Add a new Index View using Index action which has some Razor code as shown below: model IEnumerable< MVC3. After clicking on it, the Index page will display all the Files as shown below: Click on the Download link and you will get a download box as shown below (Note: I am using IE9) Conclusion. The File.
