为什么 for 循环中的 stack.Count 会使代码的值变得奇怪？

Question

当我在 for 循环中添加 stack.Count 时，它具有神奇的价值，即使我这样做了 < stack.Count + "WhatEverNumber" it never adds last int to array result nor raises an error.

static void Main()
{
    Stack<int> stack = new Stack<int>();
    stack.Push(1);
    stack.Push(2);
    stack.Push(3);
    stack.Push(4);
    stack.Push(5);
    int[] imput = StripStack(stack);
    foreach (var item in imput)
    {
        Console.WriteLine(item);
    }
    Console.Read();
}       
static int[] StripStack(Stack<int> stack)
{
    
    int[] result = new int[stack.Count];
    for (int i = 0; i < stuck.Count; i++)//here the stuck.Count is like magic
    {
        result[i] = stack.Pop();
    }
    return result;
}

我期望 stack.Count 值类似于 5，但如果您尝试向其中添加某些内容，则似乎具有最大值，例如 4。但如果我在 for 循环代码之前存储它就可以正常工作。

static void Main()
{
    Stack<int> stack = new Stack<int>();
    stack.Push(1);
    stack.Push(2);
    stack.Push(3);
    stack.Push(4);
    stack.Push(5);
    int[] imput = StripStack(stack);
    foreach (var item in imput)
    {
        Console.WriteLine(item);
    }
    Console.Read();
}       
static int[] StripStack(Stack<int> stack)
{
    int stackBigenes = stack.Count;
    int[] result = new int[stack.Count];
    for (int i = 0; i < stackBigenes; i++)
    {
        result[i] = stack.Pop();
    }
    return result;
}
