c# - 如何选择另一个列表中包含的不同元素列表？

Question

我有以下代码

new Dictionary<string,IEnumerable<Control>>()
{
    { "view1", new Control[] { contents, building, view1 }},
    { "view2", new Control[] { contents,  view2 }},
    { "view3", new Control[] { building,  view3 }
}

如何使用 linq 获取所有不同控件的列表？

结果应该是:

{
    contents,
    building,
    view2,
    view3
}

Answer 1

var controls = yourDictionary.SelectMany(pair => pair.Value).Distinct();
