Question

Question is rather simple, and somewhat pointless I understand, but still…

Database is on the server, of course, and I need an action that will when initiated grab that file from database and save it to a folder that is in my AppSettings["Active"] configuration property.

Basically,

public ActionResult Activate(int id)
{
    Project project = db.Projects.Find(id);

    var activeProjectData = project.XML; // project.XML returns byte[] type
    //For download (not in this method of course) i'm using something like return File(activeProjectData, "text/xml"); and that works ok

}

Now I want to save that file to AppSettings["Active"] path. Not to sure how to go about it. I’ve tried using System.IO.File.Create() but that didn’t quite turn out well.

Any help is appreciated.

Simply create a FileStream and use it to write the data:

string fileName = ConfigurationManager.AppSettings["Active"];
using(var fs = new FileStream(fileName, FileMode.Create, FileAccess.Write) )
{
    fs.Write(project.XML, 0, project.XML.Length);
}

If you don’t need more control than that, there is a simple helper method on the File class:

File.WriteAllBytes(fileName, project.XML);
