我将多个数组聚合成一个“大数组”时遇到困难,我认为这应该是可能的,但我不能让我的头
考虑一些返回一些dummyObject数组的方法
public class DummyObjectReceiver
{
public DummyObject[] GetDummyObjects { -snip- }
}
现在我有这个地方：
public class Temp
{
public List<DummyObjectReceiver> { get; set; }
public DummyObject[] GetAllDummyObjects ()
{
//here's where I'm struggling (in linq) - no problem doing it using foreach'es... ;)
}
}
希望有一点清楚我想要实现的目标
(作为额外的我想要排序这个数组的一个int值DummyObject有… – 但是orderby应该没有问题,我希望;)
您可以使用SelectMany方法将数组中的数组返回到数组中.
原文链接：https://www.f2er.com/javaschema/281370.htmlpublic class DummyObject {
public string Name;
public int Value;
}
public class DummyObjectReceiver {
public DummyObject[] GetDummyObjects() {
return new DummyObject[] {
new DummyObject() { Name = "a",Value = 1 },new DummyObject() { Name = "b",Value = 2 }
};
}
}
public class Temp {
public List<DummyObjectReceiver> Receivers { get; set; }
public DummyObject[] GetAllDummyObjects() {
return Receivers.SelectMany(r => r.GetDummyObjects()).OrderBy(d => d.Value).ToArray();
}
}
例：
Temp temp = new Temp(); temp.Receivers = new List<DummyObjectReceiver>(); temp.Receivers.Add(new DummyObjectReceiver()); temp.Receivers.Add(new DummyObjectReceiver()); temp.Receivers.Add(new DummyObjectReceiver()); DummyObject[] result = temp.GetAllDummyObjects();
