使用随机变量的c#λ表达式的奇怪行为

using System;

class Program
{
    static void Main(string[] args)
    {
        Random random = new Random();
        int randomNumber = random.Next(1, 100);

        Func<int, int> lambda = x => x * randomNumber;

        randomNumber = random.Next(1, 100); // 改变随机变量的值

        int result = lambda(5);
        Console.WriteLine(result); // 输出的结果可能与预期不符
    }
}

using System;

class Program
{
    static void Main(string[] args)
    {
        Random random = new Random();
        int randomNumber = random.Next(1, 100);

        int tempNumber = randomNumber;
        Func<int, int> lambda = x => x * tempNumber;

        randomNumber = random.Next(1, 100); // 改变随机变量的值

        int result = lambda(5);
        Console.WriteLine(result); // 输出的结果与预期一致
    }
}
