ForEach和foreach

Question

我正在尝试在C#中向MailAddress添加多个字符串.

如果我要使用ForEach,我的代码看起来像

        foreach (var item in GetPeopleList())
        {
            m.Bcc.Add(new MailAddress(item.EmailAddress));
        }

我现在正试图用我的foreach(即List.ForEach())来做这件事而我不能.

 public class Person
    {
        public Person(string firstName, string lastName, string emailAddress)
        {
            FirstName = firstName;
            LastName = lastName;
            EmailAddress = emailAddress;
        }

        public string FirstName { get; set; }
        public string LastName { get; set; }
        public string EmailAddress { get; set; }
    }

        static void Main(string[] args)
        {
            MailMessage m = new MailMessage();
            List<Person> people = GetPeopleList();

            m.Bcc.Add(people.ForEach(Person people =>
                {
                    //what goes here?
                }
            ));
        }

        private static List<Person> GetPeopleList()
        {
            List<Person> peopleList = new List<Person>();
            //add each person, of type Person, to the list and instantiate the class (with the use of 'new')
            peopleList.Add(new Person("Joe", "Bloggs", "Joe.Bloggs@foo.bar"));
            peopleList.Add(new Person("John", "Smith", "John.Smith@foo.bar"));
            peopleList.Add(new Person("Ann", "Other", "Ann.Other@foo.bar"));
            return peopleList;
        }

我已经尝试了几种版本/变体,但我显然做错了.我阅读了Eric Lippert关于它的页面,遗憾的是这也无济于事.

你需要类似的东西

people.ForEach(Person p => {
    m.Bcc.Add(new MailAddress(p.EmailAddress));
});

ForEach您可以ForEach在列表中添加单个项目人员,而不是添加选定的单个项目范围.

那就是说...我自己更喜欢常规foreach循环.
