@Umbraco.TypedMedia(MyProperty) is null in Umbraco 7.6.1

问题

I'm using Umbraco 7.6.1 and I'm trying to get the url for a media image using the code below in razor.

@{
   var bannerMediaItem = Umbraco.TypedMedia(Model.Content.Image); 
   var bannerUrl = bannerMediaItem.Url;
}

But bannerMediaItem is always null even though I know it exists. If I do this..

@Model.Content.Image

It returns the id of the image e.g. 1086

回答1:

In Umbraco v7.6 and above, there is now a new thing called UDI. Find out more about UDI here. https://our.umbraco.org/documentation/reference/querying/Udi

So instead of your media item having a numeric id, by default it will have an id like this: umb://media/39d3ac707d634953ab52642d5037855c

Here is how you get the media url when the id is one of the new type:

string imageUrl = Model.Content.GetPropertyValue<IPublishedContent>("headerImage").Url;

回答2:

try this

var propertyValue = content.GetPropertyValue<int>(propertyName); // this will give you the id of the media item
var media = helper.TypedMedia(propertyValue);

var url = media == null ? string.Empty : media.Url;

propertyName (string value) is the name of the property you have for your banner.

content is the IPublishedContent

helper is the UmbracoHelper that you will get from Umbraco.Web

Thanks

Ok so I was nearly right and with help from @Harsheet this worked...

@{
   var media = Umbraco.TypedMedia(Model.Content.GetPropertyValue<int>("image"));
   var thumbUrl = media.Url;
}

回答4:

var pageTitleBackground = (Model.Content.GetPropertyValue<string>("pageTitleBackground")) !=null ? Umbraco.TypedMedia((Model.Content.GetPropertyValue<int>("pageTitleBackground"))).Url : String.Empty;



style="background-image: url('@pageTitleBackground');
