    How to create media file from a byte array

    Hi all.

    I am trying to create a media file from a received byte[] array. But i cannot get it to work.

    In Umbraco 7 we could just put the HttpPostedFileBase in the umbracoFile field.

    // Umbraco 7
    var _mediaService = ApplicationContext.Current.Services.MediaService;
    var iMedia = _mediaService.CreateMediaWithIdentity("Filename", 1234, "File");
    iMedia.SetValue("umbracoFile", HttpPostedFileBase);
    _mediaService.Save(iMedia);
    

    Now this does not work in Umbraco 8. I then found a method on the MediaService called SetMediaFileContent that accept a filepath and a stream. But i dont have a filepath since the umbracoFile property is empty.

    // Umbraco 8
    IMediaService _mediaService; // Just to show the interface, since it is now DI.
    byte[] documentContent; // Just to show the byte array.
    
    var media = _mediaService.CreateMediaWithIdentity("Filename", 1234, "File");
    
    // I dunno if the umbracoFile should be set with something?
    media.SetValue("umbracoFile", ???);
    
     _mediaService.Save(media);
    
    using (Stream stream = new MemoryStream(documentContent))
    {
        // Since umbracoFile is empty, there aint no path to take.
        _mediaService.SetMediaFileContent("NoFilePath", stream);
    }
    

    Does anyone know what to do?

    Okay, so there is a little more work to do in order to get it work.

    Now you need the IContentTypeBaseServiceProvider and a Stream.

    // Umbraco 8
    using Umbraco.Core; <- Important..
    
    // Needed Interfaces
    IMediaService _mediaService; 
    IContentTypeBaseServiceProvider _contentTypeBaseServiceProvider;
    
    // The new way to do it.
    IMedia media = _mediaService.CreateMediaWithIdentity("Filename", 1234, "File");
    media.SetValue(_contentTypeBaseServiceProvider, "umbracoFile", "FilenameWithExtension", Stream);
    _mediaService.Save(media);
    

    Byte[]

    byte[] byteArray;
    
    using (Stream stream = new MemoryStream(byteArray))
    {
        media.SetValue(_contentTypeBaseServiceProvider, "umbracoFile", "FilenameWithExtension", stream);
    }
    

    HttpPostedFileBase

    HttpPostedFileBase httpPostedFileBase;
    
    media.SetValue(_contentTypeBaseServiceProvider, "umbracoFile", httpPostedFileBase.FileName, httpPostedFileBase.InputStream);
