我试过这个C#代码:
//items is the list of objects that contain the property a (int) and b(int)
var listOfInts= items.Select(p => new {p.a, p.b}).Distinct().
OrderByDescending(p => p.a).ToList();
//the result is a list of a' wew {p.a, p.b} AND not a list of integers.

我只想将所有对象的这两个属性添加到一个简单的整数列表中,即linq或lambda表达式.
提前致谢!
你可以使用SelectMany:
var listOfInts = items.SelectMany(p => new[] { p.a, p.b })
.Distinct()
.OrderByDescending(x => x)
.ToList();
