Powershell将阵列与get-random结合

Question

Hello Below is my momentary Code..

It takes seven random „meals“ out of an list and then orders them into a weekly list ordert in days.

# Food selector for the week!
#random Stuff mixed for every day.

Enum Food
{#Add Food here:
    Tacos
    Pizza
    Quesedias
    Lasagne
    Älplermakkaronen
    Apfelwähe
    Apprikosenwähe
    Rabarberwähe
    Käsekuchen
    Pasta
    Ravioli
    Empanadas
    Hamburger

}
function Food {
    $foodsOfWeek = [Enum]::GetValues([Food]) | Get-Random -Count 7

    foreach ($day in [Enum]::GetValues([DayOfWeek])) {
        ([string]$day).Substring(0, 3) + ': ' + $foodsOfWeek[[DayOfWeek]::$day]
    }

}

I am trying to make it so it can be combined with more arrays like this:

Enum Food
{#Add Food here:
    Tacos
    Pizza
    Quesedias
    Lasagne
    Älplermakkaronen
    Apfelwähe
    Apprikosenwähe
    Rabarberwähe
    Käsekuchen
    Pasta
    Ravioli
    Empanadas
    Hamburger
}
Enum Food2
{#Add Fish Stuff here:
    Whatever Fish I want^^ :)
}

#and an array for meat(like steak)
.....

#an array for som healthy food!
.....



function Food {
    $foodsOfWeek = [Enum]::GetValues([Food]) | Get-Random -Count 7

    foreach ($day in [Enum]::GetValues([DayOfWeek])) {
        ([string]$day).Substring(0, 3) + ': ' + $foodsOfWeek[[DayOfWeek]::$day]
    }

}

So it does combine them and takes RANDOM out of them all but I can set criterias like it must have one at least from every "List". Perfect would be: Every week at least once —> Meat, Fish, Vegetables and then the rest is random from the first list...

I hope you guys can help me :)

Kind regards Alex

Albeit this may not be exactly what you are looking for, you could try the following:

{
# Food selector for the week!
#random Stuff mixed for every day.

Enum FastFood
{#Add Food here:
Tacos
Pizza
Quesedias
Lasagne
Älplermakkaronen
Apfelwähe
Apprikosenwähe
Rabarberwähe
Käsekuchen
Pasta
Ravioli
Empanadas
Hamburger

}

Enum Meat
{#Add Food here:
Steak
Chop
Beaf
Lamb
Pork
Chicken
}

function Food {
#either
  $Foods =  [Enum]::GetValues([FastFood]) + [Enum]::GetValues([Meat])
#or
  $Foods =  [Enum]::GetValues([FastFood])
  $Foods += [Enum]::GetValues([Meat])

$foodsOfWeek = $Foods | Get-Random -Count 7

foreach ($day in [Enum]::GetValues([DayOfWeek])) {
    ([string]$day).Substring(0, 3) + ': ' + $foodsOfWeek[[DayOfWeek]::$day]
}

The $Foods variable of course is not an Enum type but an object collection, however you can then generate your random 'meal' of the day & have the option to extend the list as additional categories are added. To access a specific entry you can index as follows: $Foods[10]

The current variable contains 19 elements ($Foods.count)

Hope it helps,
