如何在C# 7中检查ValueTuple列表是否为List<ValueTuple>类型

using System;
using System.Collections.Generic;

public class Program
{
    public static void Main()
    {
        var tupleList = new List<(int, string)>
        {
            (1, "One"),
            (2, "Two"),
            (3, "Three")
        };

        if (tupleList is List<(int, string)>)
        {
            Console.WriteLine("tupleList is of type List<(int, string)>");
        }
        else
        {
            Console.WriteLine("tupleList is not of type List<(int, string)>");
        }
    }
}
