Resolve multimedia component URL at runtime

Question

I need to resolve the real URL for an image (multimedia component) only knowing its tcm-uri and the publication id.

I've tried this way:

        var uri = new TcmUri("tcm:13-5093");
        var binaryLink = new BinaryLink(13);
        var link = binaryLink.GetLink(uri.ToString(), "", "", "", false);

        if (link.IsResolved)
            var image = link.Url;

but my link variable results always unresolved. I've also tried this way:

BinaryMetaFactory binaryMetaFactory = new BinaryMetaFactory();
BinaryMeta binaryMeta = binaryMetaFactory.GetBinaryMeta("tcm:13-5093");

if(binaryMeta!=null) {
    Response.Write("Path of the binary: " + binaryMeta.UrlPath);
}

But even this was not a good solution. My multimedia components are all correctly published so I don't have any idea. Can anyone help me?

Answer 1

It looks like uri.ToString() is converting as ItemId. Hence it's not resolving.

Try this way by passing full TCM ID:

String binaryUrl = String.Empty;
BinaryLink binaryLink = new BinaryLink(13);
Link link = binaryLink.GetLink("tcm:13-5093", "", "", "", false);
if (link != null && link.IsResolved)
{
    binaryUrl = link.Url;
}
