Say the class that holds the permissions is named Permission, you can define an extension method:

public static class PermissionExtensions
{
    public static object SelectProperty(this Permission obj, string variable)
    {
        return obj.GetType().GetProperty(variable).GetValue(obj, null);
    }
}

You can use this in your query like this:

(from s in dc.Permissions where s.dashboardname == permission select s)
    .Single().SelectProperty(variable);

This doesn't select the property in the query but instead gets it from the instance.
