Asp.net how to Delete specific List Items from a Model

Question

I have a model which contains a list and I need to remove/delete all items from the model based on the MarkedForDeletion value.

So far I've tried the following but this is not valid, I would prefer to not loop through the records using a for loop.

Models cs

public class CategoryModel
{
    public string Label { get; set; }
    public List<ItemModel> Items { get; set; }
}

public class ItemModel
{
    public string Label { get; set; }
    public bool MarkedForDeletion { get; set; )
}

Attempted Solution (not a valid statement)

CategoryModel.Items.Where(x => x.MarkedForDeletion = true).Remove;

Have you tried RemoveAll() which will remove all the elements that match the conditions defined by the specified predicate?

CategoryModel.Items.RemoveAll(x => x.MarkedForDeletion);

I had tried variations with remove and removeall but can't have tried that as this works now. Thanks
