    U8 - How to display the media URL from Media Picker property?

    I am trying to display the URL of a media item that has been selected from a media picker property. Any assistance would be greatly appreciated.

    I have a nested content datatype:

    var contentBlocks = Model.Value<IEnumerable<IPublishedElement>>("contentBlocks");

    and I am then trying to loop through these, and get a node from a content picker, and then get a media picker property named 'image' from this node:

    foreach(var item in contentBlocks){
    var contentBlock = item.GetProperty("block").Value<IPublishedElement>();
    var imageUrl = contentBlock.GetProperty("image").Value().Url;
}

    but I am having trouble retrieving the Url into the 'imageUrl' var. I am receiving the error "Cannot assign method group to an implicitly-typed variable", and I've tried a few different things but still can't get the Url property from the Image.

    Hi Jonok

    This is how you do it in v8.

    var imageUrl = Model.Value<IPublishedContent>("imageAlias")?.Url ?? "";

    One other thing Paul - what do the question marks do? Do they check if the property exists before attempting to get the URL?

    Hi Jonok Yes, they check for nulls.

    The ?. is a Null conditional operator:

    https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/operators/null-conditional-operators

    And the ?? is a Null coalescing operator:

    https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/operators/null-coalescing-operator

    Thanks very much Paul. Not sure why I was using IPublishedElement (I think I saw it on some example code somewhere), but changing it to IPublishedContent has fixed it.

    An element does not have an url :-)

    It only lives as a property on a document, like nested content.
