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 "";
}
