Hi Nguyen

Do you have media Id already? After image upload you have to have media Id, then you can easily set media id to content node media picker like that:

var node =
ApplicationContext.Services.ContentService.GetById(productId);

var locaUdi = Udi.Create(Constants.UdiEntityType.Media, media.Key);

node.SetValue( "mediaPicker", locaUdi.ToString() );
cntsvc.SaveAndPublishWithStatus(node);

Thanks, Alex

Oh again you are. I will try Thank you very much

So, How to get media Id from Url or alias image

I want rename image url when save&public content.

So media id has not yet?

If anyone is having trouble with Umbraco 8 then this is how I do it.

You basically need to get the UDI of the media item and use this to pass into the media picker field.

var content = _contentService.GetById("content-node-id-here");
if (content != null)
{
    content.SetValue("basicStringValue", "some-string-content");
    content.SetValue("anotherBasicStringValue", "some-string-content");

    IMedia media = _mediaService.GetById(mediaId);
    if(media != null)
    {
        content.SetValue("logo", media.GetUdi());
    }

    if(image != null)


    _contentService.SaveAndPublish(content);
}
