我的错误在我的 for 语句中，语法错误是说我的构造函数没有接受三个参数。

        string[] first = new string[20] { "Scott", "Ramona", "Todd", "Melissa", "Naomi", "Leland", "Conor", "Julie", "Armondo", "Leah",
                                          "Frank", "Peter", "Ila", "Mandy", "Sammy", "Gareth", "Garth", "Wayne", "Freddy", "Mark" };

        string[] last = new string[20] { "Kennedy", "Kennedy", "Kennedy", "Kennedy", "Kennedy", "Kennedy", "Carrel", "MaloyTheBeautiful", "Johnson", "Smith", 
                                         "Sinatra", "Clemens", "Eels", "Johnson", "Eels", "Thompson", "Brooks", "World", "Crugar", "Thomas" };
        DateTime[] birth = new DateTime[20];
        birth[0] = new DateTime(1987, 22, 7);
        birth[1] = new DateTime(1962, 15, 9);
        birth[2] = new DateTime(1984, 21, 4);
        birth[3] = new DateTime(1977, 24, 1);
        birth[4] = new DateTime(1983, 12, 8);
        birth[5] = new DateTime(1979, 14, 1);
        birth[6] = new DateTime(1965, 19, 9);
        birth[7] = new DateTime(1968, 21, 2);
        birth[8] = new DateTime(1980, 22, 7);
        birth[9] = new DateTime(1982, 20, 7);
        birth[10] = new DateTime(1984, 19, 4);
        birth[11] = new DateTime(1968, 11, 9);
        birth[12] = new DateTime(1968, 21, 8);
        birth[13] = new DateTime(1975, 5, 2);
        birth[14] = new DateTime(1945, 15, 3);
        birth[15] = new DateTime(1969, 14, 6);
        birth[16] = new DateTime(1987, 141, 4);
        birth[17] = new DateTime(1976, 23, 5);
        birth[18] = new DateTime(1989, 28, 6);
        birth[19] = new DateTime(1988, 23, 9);

        // Populate Array Person[] People = new Person[20];     


        for (int i = 0; i < People.Length; i++)
        {
            People[i]= new Person(first[i], last[i], birth[i]);
        }

我的班级看起来像这样

public class Person
{
    private string _firstname;
    private string _lastname;
    private DateTime _birthDate;

    public void Personn(string firstname, string lastname, DateTime birthDate)
    {
        _firstname = firstname;
        _lastname = lastname;
        _birthDate = birthDate;
    }

    public string Firstname
    { get { return _firstname; } }

    public string Lastname
    { get { return _lastname; } }

    public DateTime Birthdate
    { get { return _birthDate; } }
}

代替

 public void Personn(string firstname, string lastname, DateTime birthDate)

利用

 public Person(string firstname, string lastname, DateTime birthDate)

您认为构造函数只是一种方法。您拼错了班级名称。

改变这个：

    public void Personn(string firstname, string lastname, DateTime birthDate)

至：

    public Person(string firstname, string lastname, DateTime birthDate)

构造函数没有任何返回类型。void从您的构造函数中删除。

检查您的构造函数，它不应该有返回类型，并且应该与类同名。

我认为你应该使用而不是这一行：

 public void Personn(string firstname, string lastname, DateTime birthDate)

这个：

 public Person(string firstname, string lastname, DateTime birthDate)

因为目前它是一个 void 方法而不是构造函数，但是在这种情况下你有一个没有参数的默认构造函数。这可能是您的问题的原因！
