.NET相当于Java的List.subList（）？

Question

是否有一个.NET的等效Java的List.subList()适用于IList<T> ？

Answer 1

使用LINQ

list.Skip(fromRange).Take(toRange - fromRange)

Answer 2

For the generic List<T> , it is the GetRange(int, int) method.

Edit: note that this is a shallow copy, not a 'view' on the original. I don't think C# offers that exact functionality.

Edit2: as Kamarey points out, you can have a read-only view:

List<int> integers = new List<int>() { 5, 6, 7, 8, 9, 10, 11, 12 };
IEnumerable<int> view = integers.Skip(2).Take(3);
integers[3] = 42;

foreach (int i in view )
  // output

The above will print 7, 42, 9.

Answer 3

GetRange是你的答案
