LINQ where condition with string operations

Question

I get this error when that linq code runs. I try many string methods like concat,join,etc. But LINQ doesn't permit string operations. Finally error is runtime error.

ERROR: System.NotSupportedException: 'System.String Format(System.String, System.Object, System.Object)'

public List<ItemEntity> GetItems(List<string> codeList)
{
    return ExecuteCrud(session =>
    {
        return (from Item in session.Query<ItemEntity>()
                where (codeList.Contains(Item.code) || codeList.Contains($"{Item.Id.ToString().PadLeft(10, '0')}-{ Item.ItemId.ToString().PadLeft(12, '0')}"))
                select Item).ToList();
    });
}
