错误方法必须有一个返回类型

Question

这是我的类文件，我得到一个错误的“方法必须有一个返回类型”

public class Users 
{ 
    public string FirstName { get; set; } 
    public string LastName { get; set; } 
} 
public class UsersList : List<Users> 
{ 
    public UsersList 
{ 
    this.Add(new Users() { FirstName = "John", LastName = "Lock"}); 
    this.Add(new Users() { FirstName = "James", LastName = "Soyer"}); 
    this.Add(new Users() { FirstName = "Jack", LastName = "Sephered"}); 
} 
}
