请考虑C#中的元组列表.这与原始元组(不是Value Tuple)有关.如果我知道元组列表中的一个项目,我怎样才能获得List的索引？

        List<Tuple<double, int>> ListOfTuples2 = new 
        List<Tuple<double, int>>();

        double doubleTuple = 5000;
        int intTuple = 7;

        ListOfTuples2.Add(Tuple.Create(doubleTuple, intTuple));
        ListOfTuples2.Add(Tuple.Create(5000.00, 2));
        ListOfTuples2.Add(Tuple.Create(5000.25, 3));
        ListOfTuples2.Add(Tuple.Create(5000.50, 4));
        ListOfTuples2.Add(Tuple.Create(5000.25, 5));


        /* How can I get the Index of the List if 
        doubleTuple = 5000.25 ?  */
