PowerShell脚本开发需求：实现200种餐食编号映射与周饮食计划

Hey there! Let's get your script to properly link food items with their numbers and generate a usable weekly meal plan. Your current code generates random numbers from 1-200, but we need to tie those numbers to actual food names first. Here's a step-by-step solution:

1. Create a Mapping of Numbers to Food Items #

First, we need to associate each number (1 to 200) with a specific food. The easiest way to do this is with a hashtable (a key-value pair structure), where the key is the number and the value is the food name. Alternatively, you can use an array (since arrays are zero-indexed, we'll just add 1 to the index to get the number).

Here's how to set this up:

# Replace this example list with your full 200 food items
$allFoods = @(
    "塔可",
    "披萨",
    "汉堡",
    "凯撒沙拉",
    "番茄意面",
    "日式寿司",
    "牛肉拉面",
    # ... keep adding until you have 200 items
    "水果燕麦碗"
)

# Create a hashtable to map numbers (1-200) to foods
$numberedFoods = @{}
for ($index = 0; $index -lt $allFoods.Count; $index++) {
    $foodNumber = $index + 1  # Start numbering at 1
    $numberedFoods[$foodNumber] = $allFoods[$index]
}

If your food list is stored in a text file (one food per line), you can load it like this instead:

$allFoods = Get-Content -Path "C:\Path\To\Your\FoodList.txt"

2. Update the Random Selection Function #

Next, we'll rewrite your function to pick 7 unique random numbers, then pair each number with its corresponding food and format it as a weekly plan (with days of the week for clarity):

function Get-WeeklyMealPlan {
    Param(
        [hashtable]$FoodMapping
    )

    # Pick 7 unique random food numbers from the mapping
    $selectedNumbers = $FoodMapping.Keys | Get-Random -Count 7

    # Pair numbers with foods and assign to days of the week
    $days = @("周一", "周二", "周三", "周四", "周五", "周六", "周日")
    $mealPlan = @()

    for ($i = 0; $i -lt 7; $i++) {
        $mealPlan += [PSCustomObject]@{
            日期 = $days[$i]
            餐食编号 = $selectedNumbers[$i]
            餐食名称 = $FoodMapping[$selectedNumbers[$i]]
        }
    }

    return $mealPlan
}

3. Generate and Display the Plan #

Finally, call the function and output the result in a readable format:

# Generate the weekly plan
$weeklyMeals = Get-WeeklyMealPlan -FoodMapping $numberedFoods

# Print the plan
Write-Host "📅 本周餐食计划：" -ForegroundColor Cyan
$weeklyMeals | Format-Table -AutoSize

Bonus: Quick Array Alternative #

If you prefer using an array instead of a hashtable (since your numbers are sequential), you can simplify the selection step. Just pick a random index, add 1 to get the number, and grab the food directly:

function Get-WeeklyMealPlan {
    Param(
        [array]$FoodList
    )
    $selectedIndices = 0..($FoodList.Count - 1) | Get-Random -Count 7
    $days = @("周一", "周二", "周三", "周四", "周五", "周六", "周日")
    $mealPlan = @()

    for ($i = 0; $i -lt 7; $i++) {
        $foodNumber = $selectedIndices[$i] + 1
        $mealPlan += [PSCustomObject]@{
            日期 = $days[$i]
            餐食编号 = $foodNumber
            餐食名称 = $FoodList[$selectedIndices[$i]]
        }
    }
    return $mealPlan
}

# Call it with your food array
$weeklyMeals = Get-WeeklyMealPlan -FoodList $allFoods

Now your script will generate a clear, numbered weekly meal plan with actual food names instead of just random numbers!
