怎么实现在List结果中搜索？

[OS_50]

假设先从数据库搜索Customer 的name是 *Zhang?

返回一个List<Customer>结果集，现在怎么实现在这个结果中搜索，

条件还是 "Customer 的name是 *Zhang? "
(*?等正则表达式一定要支持)

List<Customer> Search(List<Customer> customer, string filter)
{
return customer.Find(
delegate(Customer cus)
{
return Regex.IsMatch(cus.name, filter);
});
}
