注意：这段代码编写得很快，而且，当它编译时，我还没有彻底测试过。



首先，如果你的代码正在创建'Person的实例列表，你想要执行一些筛选规则姓名，这是一个例子：

Note: this code was written quickly, and, while it compiles, I have not tested it thoroughly.

First, if your code is creating the list of instances of 'Person and you want to enforce some screening rule about names, here's an example:

public class Person
{
    private static List<string> surnamesInUse = new List<string>();
    private static List<string> firstNamesInUse = new List<string>();

    private string lname;
    private string lsurname;

    public Person(string name, string surname)
    {
        if (name == String.Empty || surname == String.Empty)
        {
            throw new ArgumentException(

name和surname不能为空字符串）;
}

lname = name.ToLower（）;
lsurname = surname.ToLower（）;

if（lname == lsurname）
{
抛出新的ArgumentException（

"name and surname cannot be empty strings"); } lname = name.ToLower(); lsurname = surname.ToLower(); if (lname == lsurname) { throw new ArgumentException(

名称和姓氏不能独立于案例） ;
}

if（firstNamesInUse.Contains（lname））
{
抛出新的DuplicateNameException（

"name and surname cannot match independent of case"); } if (firstNamesInUse.Contains(lname)) { throw new DuplicateNameException(
