You should be able to convert using the Umbraco helper class, which is available in controllers derived from an Umbraco surface or API controller. Like this:

IPublishedContent mediaItem = Umbraco.TypedContent(media);

Where media string is your umb://media/ document.

Hi Dan

I tried doing this.

            string media = (ctx.cmsPropertyDatas.Where(x2 => x2.propertytypeid == rwupload.id && x2.contentNodeId == x.nodeId).First<cmsPropertyData>().dataNtext == null) ? "none" : ctx.cmsPropertyDatas.Where(x2 => x2.propertytypeid == rwupload.id && x2.contentNodeId == x.nodeId).First<cmsPropertyData>().dataNtext;
            IPublishedContent mediaItem = Umbraco.TypedContent(media);
            string murl = mediaItem.UrlWithDomain();


            RARiskWatch rw = new RARiskWatch(id, title, body, murl);

and my web Api returns this exception:

      <Error>
      <Message>An error has occurred.</Message>
      <ExceptionMessage>
      Object reference not set to an instance of an object.
      </ExceptionMessage>
      <ExceptionType>System.NullReferenceException</ExceptionType>
      <StackTrace>
      .......
      </StackTrace>
      </Error>

Im not sure where im doing wrong. Thank you for your help!

You probably need to do a few null checks. Also, it looks like your media string could be equal to the word "none" in some circumstances, which isn't a valid string to resolve.

So if you go:

IPublishedContent mediaItem = Umbraco.TypedContent(media);

and media doesn't resolve to IPublishedContent then when you try and access mediaItem it can potentially be null. So when you call UrlWithDomain() on a null object, you're going to get a null reference exception.

Can you debug and check what the value of "media" is?

Hi Dan,

for the string media has a value of "umb://media/572ab5ce2ea54640bf124e922254c067"

and the

IPublishedContent mediaItem was null

Ahhh, just thinking - as it's media you might need to use:

IPublishedContent mediaItem = Umbraco.TypedMedia(media);

Give that a go!

Hi Dan,

I tried using TypeMedia but i still return a null exception.

I was looking through the Documentations, TypeMedia(int ID) requires an input of integer typed. However in this case, my ID is a GUID typed which is 'umb://media/572ab5ce2ea54640bf124e922254c067'.

1) Is there a way to return a media file using GUID of the media file??

2) Or is there a way to return the ID of a media file using GUID of the media file?

3) Or is there any helper class that has an input of GUID instead of Integer

Thanks so much for your help

Melvin

I had this problem myself, using TypedContent did not work for media UDI's, however using TypedMedia solved my problem.

TypedMedia constructor is not limited to Int ID's only (even though the documentation does not list the other implementations). It also support Udi, Guid and a string representation of the Id.

This is directly from the UmbracoHelper implementation:

    public IPublishedContent TypedMedia(Udi id);
    public IPublishedContent TypedMedia(Guid id);
    public IPublishedContent TypedMedia(int id);
    public IPublishedContent TypedMedia(string id);

Hi Christian,

I tried using

public IPublishedContent TypedMedia(Guid id);

but still got a null exception.

Managed to solve my problem with the link that John shared:

            string media = (ctx.cmsPropertyDatas.Where(x2 => x2.propertytypeid == rwupload.id && x2.contentNodeId == x.nodeId).First<cmsPropertyData>().dataNtext == null) ? "none" : ctx.cmsPropertyDatas.Where(x2 => x2.propertytypeid == rwupload.id && x2.contentNodeId == x.nodeId).First<cmsPropertyData>().dataNtext;
            media = media.Remove(0, 12);
            IMedia content = UmbracoContext.Current.Application.Services.MediaService.GetById(Guid.ParseExact(media, "N"));
            IPublishedContent mediaItem = content == null ? null : Umbraco.TypedMedia(content.Id);
            string murl = mediaItem.Url();

and i managed to get the url path of my media files.

Thanks guys!

I've been struggling with this problem and managed to solve it, so I thought why not share it. Here's my method for getting media url of Member image property:

public static string GetImageUrl(IMember member, string imageProperty)
    {
        string url = "";

        if (member.GetValue(imageProperty) != null)
        {
            IPublishedContent image = Umbraco.Web.Composing.Current.UmbracoHelper.Media(member.GetValue(imageProperty));
            url = image.Url;
        }

        return url;
    }

Hope it helps someone one day!
