c# - 元组到元组的转换

Question

有什么简单的方法可以转换Tuple<int, string, Guid>吗？至 Tuple<int, string> ？

更新:... 转换 List<Tuple<int, string, Guid>>至 List<Tuple<int, string>> ？

Answer 1

确定:

Tuple<int, string, Guid> t1 = ...;
Tuple<int, string> t2 = new Tuple<int, string>(t1.Item1, t1.Item2);

更新:
随着列表:

List<Tuple<int, string, Guid>> t1s = ...;
List<Tuple<int, string>> t2s = t1s.Select(t1 => new Tuple<int, string>(t1.Item1, t1.Item2)).ToList();
