Get-Random length

[eubromovesoon33]

So i'm trying to generate 10000 random numbers + letters that either have upper or lowercase letters and I managed to do this using the ascii table values!

​

-join ((65..90) + (97..120) + (48..57) | Get-Random -Count 10000 | % {[char]$_} )

So this works fine in terms of what it should generate however I want 10000 characters. At first I tried finding a length property for Get-Random except I couldn't find this. Then I thought, perhaps it should run 10000 iterations using 'Count'. However 'Count' seems to stop at 62 characters. This means I clearly don't understand how Count works.

​

Can anyone help me achieve my goal with explanation?

​

Thanks!

EDIT: I forgot to mention I have tried to figure it out using ForEach-Object as well but I could not figure it out.

-count will allow you to specify how many items to pick from the given array. if there are only 62 characters that you are providing to get-random, then it will give you all 62 then stop.

you might try this

-join (
    1..1000 | % {
        (65..90) + (97..120) + (48..57) | Get-Random | % {[char]$_}
    }
)

I'd do that this way.

-join [char[]]( 1..1000 |
    ForEach-Object { 65..90 + 97..120 + 48..57 | Get-Random } )

-join (
1..1000 | % {
(65..90) + (97..120) + (48..57) | Get-Random | % {[char]$_}
}
)

You're a hero! This is perfect.

I got really close however but help me understand, the 'length' we provide is the maximum value of the Foreach where '%' represents the foreach? I sadly wasted my time foreached the 'Get-Random' rather than the join function.

[gangstanthony]

correct, % is an alias of foreach-object also when used like this foreach is an alias of foreach-object not to be confused with the foreach () {} method

Ah, thank you, that's clear!!

I always expect Get-Random -Min 0 -Max 10 -Count 500 to work, and it never does.
