錯誤方法必須有一個返回類型

Question

這是我的類文件，我得到一個錯誤的「方法必須有一個返回類型」

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"}); 
} 
} 

我試圖綁定到一個集合的靜態資源定製實例

Answer 1

public UsersList() 
{ 
    ... 
}
