    Razer .Where(Id One Of Multiple Ids)

    Razor

    I'm tryin to do a .Where() Filter on my nodes with multiple Ids.

    I have been trying to use  .ContainAny() with no luck so far.

    Here's what i got:

    var values = new Dictionary<string,object>();
    var keywords = new List<string>();
           
    keywords.Add("1222");
    keywords.Add("1193");
    values.Add("keywords",keywords);

    // Doesn't Work     
    //Children = Children.Where("Id.Contains(1222)"); 

    // Works
    //Children = Children.Where("Convert.ToString(Id).Contains(\"1222\")"); 

    // Doesn't Work
    //Children = Children.Where("Id.Contains(keywords)", values);
    //Children = Children.Where("Convert.ToString(Id).Contains(keywords)", values); 
    //Children = Children.Where("Convert.ToString(Id).ContainsAny(keywords)", values); 

    Appreciate your help.

    There are a few problems with what you are trying to do:

    Firstly, in general LINQ queries then Contains() operates on an IEnumerable collection not on a single Int. So given that the Id of a node is of type Int, how can an Int contain anything? Saying Id.Contains(1234) makes no sense. How can a single integer number contain anything?

    Your second problem is that Where in Umbraco razor doesn't, as far as I know, implement Contains.

    However, if you have a list of node Ids and want to find nodes in a list of child nodes then you could do something like this:

    List idsList = new List() { 1064, 1065 };

dynamic foundNodes = CurrentModel.Descendants(x => idsList.Contains(x.Id));

foreach (var n in foundNodes)
{
@n.Id
}

    Thanks Diplo.

    Love the cheatsheet, been missing it for awhile :)

    You got me thinking and i'll take a different approach, something like:

    DynamicNodeList Children = Model.NodeById (List< object > Ids)
