如何拆箱元组？

Question

我有盒装元组：

(int, string) tuple = (1, "abc");
object box = tuple;

如何从box获取元组？将 object 转换回元组的正确语法是什么？

我的尝试：

var deconstruct = (int, string)box;

明显错误：

Error CS1525 Invalid expression term 'int'

Error CS1525 Invalid expression term 'string'

Error CS1002 ; expected

Error CS0201 Only assignment, call, increment, decrement, await, and new object expressions can be used as a statement

Answer 1

ValueTuple<int, string> t = (ValueTuple<int, string>)box;

或

(int, string) t = ((int, string))box;
