这是一个有问题的基本类TheProperty
:
class BasicClass {
public BasicClass() {
TheProperty = new Object();
Stamped = DateTime.Now;
}
public object TheProperty { get; set; }
public DateTime Stamped { get; private set; }
}
这是基本列表:
class BasicList {
private List<BasicClass> list;
public BasicList() {
list = new List<BasicClass>();
}
public BasicClass this[object obj] {
get { return list.SingleOrDefault(o => o.TheProperty == obj); }
}
public void Add(BasicClass item) {
if (!Contains(item.TheProperty)) {
list.Add(item);
}
}
public bool Contains(object obj) {
return list.Any(o => o.TheProperty == obj); // Picked this little gem up yesterday!
}
public int Count { get { return list.Count; } }
}
我想添加一个类BasicList
,它将返回一个项目数组。
我可以这样写,使用传统的 C#:
public object[] Properties() {
var props = new List<Object>(list.Count);
foreach (var item in list) {
props.Add(item.TheProperty);
}
return props.ToArray();
}
