Question

        var groups = new List<Group>
        {
           new Group{
               Name = "Train", 
               Members = new List<Colleague>{
                   {FirstName = "Thomas", LastName = "Tank"},
                   {FirstName = "Honey", LastName = "Booboo"}
               }  
           }, 
           new Group{Name = "Bus"}
        };

我在'FirstName'和'LastName'下得到一个红色下划线...意思是我错误地初始化了...

如何初始化该（同事）列表？我认为我错误地初始化该列表（成员）......

修改：为了让事情更清楚，

public class Group
{
    public string Name { get; set; }
    public List<Colleague> Members { get; set; }
}

编辑：跟随Kirk Woll进行讨论：

这就是我对你的建议所做的。成员是空的但是......

var groups = new List<Group>
        {
           new Group
           {
               Name = "Train", 
               Members = new List<Colleague>{
                   new Colleague { FirstName = "Thomas", LastName = "Tank" },
                   new Colleague { FirstName = "Jet", LastName = "Starr" }
               }

           }, 
           new Group{Name = "Bus"}
        };

总而言之，在群组初始化之后有一个断点。每个组（x2）都定义了Name，但在第一个Group（'Train'）中Members = null。会员必须初始化！干杯。

你想：

Members = new List<Colleague>
{
    new Colleague { FirstName = "Thomas", LastName = "Tank" },
    new Colleague { FirstName = "Honey", LastName = "Booboo" }
}

因为它是您尝试添加的Colleague列表。
