    how to check for null value with IPublishedContent

    Hi,

    I'm having a IPublishedContent query:

    var announcement = Model.Content.DescendantsOrSelf().Where(x => x.DocumentTypeAlias == "AnnouncementItem").First();

    however this line crashes when there are no announcement items.

    I looked for some documentation here: http://our.umbraco.org/documentation/Reference/Mvc/querying but couldn't found anything.

    Does anyone have an idea how to check for null in this query?

    thanks for your help,

    Anthony

    Hi,

    Use the method FirstOrDefault and check if it is null then.

    Thanks a lot Marcio,

    This worked:

    var announcement = Model.Content.DescendantsOrSelf().Where(x => x.DocumentTypeAlias == "AnnouncementItem").FirstOrDefault();

    Greetings,

    Anthony
