说明：

1、密码一共8位。

2、由2个数字，2个大写字符，2个小写字符，2个特殊字符组成。

3、字符的次序是随机组成的。

复制代码 代码如下:

function CreatePassword

{

$figure=1,2,3,4,5,6,7,8,9;

$capital="Q","W","E","R","T","Y","U","I","O","P","A","S","D","F","G","H","J","K","L","Z","X","C","V","B","N","M";

$lowercase="q","w","e","r","t","y","u","i","o","p","a","s","d","f","g","h","j","k","l","z","x","c","v","b","n","m";

$specialCharacter="~","!","@","#","$","%","^","&","*","(",")","-","+";

$order=New-Object System.Collections.ArrayList;

for($i=0;$i -lt 8;$i++)

{

[void]$order.Add($i);

}

$newOrder=@();

for($i=0;$i -lt 8;$i++)

{

$produceOrder=Get-Random -InputObject $order;

$newOrder+=$produceOrder;

$order.Remove($produceOrder);

}

$newPassword=@();

foreach($i in $newOrder)

{

if($i -eq 0)

{

$index=Get-Random -Maximum 8;

$newPassword+=$figure[$index];

}

if($i -eq 1)

{

$index=Get-Random -Maximum 8;

$newPassword+=$figure[$index];

}

if($i -eq 2)

{

$index=Get-Random -Maximum 25;

$newPassword+=$capital[$index];

}

if($i -eq 3)

{

$index=Get-Random -Maximum 25;

$newPassword+=$capital[$index];

}

if($i -eq 4)

{

$index=Get-Random -Maximum 25;

$newPassword+=$lowercase[$index];

}

if($i -eq 5)

{

$index=Get-Random -Maximum 25;

$newPassword+=$lowercase[$index];

}

if($i -eq 6)

{

$index=Get-Random -Maximum 12;

$newPassword+=$specialCharacter[$index];

}

if($i -eq 7)

{

$index=Get-Random -Maximum 12;

$newPassword+=$specialCharacter[$index];

}

}

return $newPassword -join "";

}
