Linq where based on List of integers

I have a win forms application where we are filtering based on numerous criteria. One is a multi select dropdown. This value is an integer and I am having getting the command to work.

I tried the below, but cannot use a contains on an integer. just showing here so I can give you an idea on what I would like to do.

    private List<int> GetSelectedIntVals()
    {
        List<int> intVals = new List<int>();
        foreach (var item in ddlSearchQueueStage.CheckBoxItems)
        {
            if (item.Checked == true)
            {
                intVals.Add(st.GetStageNumberFromText(item.Text));
            }
        }
        return intVals;
    }


    public void FilterBatch(SearchCriteria searchCriteria)
    {
        var FilteredBatch = (from t in BatchList select t).ToList();

        // This is where having issue
        FilteredBatch = FilteredBatch.Where(p => p.Stage.Contains(searchCriteriaQueue.stageVal).ToList();  
        .
        .
        .
        .
        RebuildScreen();
    }

Thanks in advance. I have looked and tried a few other options but have not been able to get working.

Assuming that searchCriteriaQueue.stageVal is a collection of integers (since you say it's a multi-select dropdown), you just have the Contains call backwards:

    FilteredBatch = FilteredBatch.Where(p => searchCriteriaQueue.stageVal.Contains(p.Stage)).ToList();
