Umbraco通过别名查找内容

Question

So far, I am fetching a content by id and works fine.

 var footerSection = Umbraco.TypedContent(1174);

Although, I am trying to have the same result by querying via document alias and it is not working:

 var umbracoHelper = new UmbracoHelper(UmbracoContext.Current);
    var foundFooterSection = umbracoHelper.TypedContentAtRoot().FirstOrDefault(x => x.DocumentTypeAlias == "footerSection");

I am pretty sure that document alias is "footerSection" - I have this information even from the first (successful) call but it returns null.

Any reasons that might cause this?

Any help is welcome!

Your footer node is probably a descendant of root so you probably need to adjust the code a little bit.

var foundFooterSection = umbracoHelper
    .TypedContentAtRoot()
    .SelectMany(root => root.Descendants())
    .Where(x => x.DocumentTypeAlias == "footerSection")
    .ToList();
