【问题描述】：

所以我有一个脚本，您可以在其中输入名字中间名首字母和姓氏，并从中创建登录名，但有时可能需要输入自定义用户名我这样做？登录名确实显示了我想要的方式，但是当我按 C 或 c 时 if 语句不允许我更改它

任何帮助提前谢谢

#getting user information
Write-Host "Gathering information for new account creation."
Write-Host
$firstname = Read-Host "Enter in the First Name"
Write-Host
$middlename = Read-Host "Enter in Middle Initial"
Write-Host
$lastname = Read-Host "Enter in the Last Name"
Write-Host
$fullname = "$firstname $lastname"
#getting samaccountname with first letter of first name, first letter of middle name, first 4 letters 
of last name
$i = 1
$p = 4
$logonname = $firstname.substring(0,$i).tolower() + $middlename.Substring(0,$i).tolower() + 
$lastname.Substring(0,$p).tolower()



$confirm = Read-Host "Is [$logonname] correct  or would you like to change it (Y/C)"
  if ($confirm -eq "y" -or "Y"){
#proceed

     } else { write-host 
     $logonname = Read-Host "Enter Custom User Name"
 }

使用 ANR [Ambiguous Name Resolution，我认为] 来获取所有相似的名称，找到具有最高数字的名称，增加该数字，最后使用它来制作您的新名称。
同上@Lee_Dailey。除此之外，您需要检查用户是否实际输入了某些内容，并且它不仅仅是空格。例如，如果有人在 Read-Hostprompts 之一中没有输入任何内容，您的脚本将出错。如果用户输入的姓氏少于 4 个字符（碰巧我的是..），您的脚本将出错。如果用户输入空格，您可能会得到错误的登录名。简而言之，您需要重新考虑这一点，并对每个用户输入添加检查。
是的，我明白，这就是为什么我要求他们确认名称，如果没有，则让他们输入自定义登录名

好的，这样我就可以让它工作了

#getting user information
Write-Host "Gathering information for new account creation."
Write-Host
$firstname = Read-Host "Enter in the First Name"
Write-Host
$middlename = Read-Host "Enter in Middle Initial"
Write-Host
$lastname = Read-Host "Enter in the Last Name"   
Write-Host
$fullname = "$firstname $lastname"
#getting samaccountname with first letter of first name, first letter of middle name, 
first 4 letters of last name
$i = 1
$p = 4
$logonname = $firstname.substring(0,$i).tolower() + 
$middlename.Substring(0,$i).tolower() + $lastname.Substring(0,$p).tolower()

Do{
Write-Host
$confirm = Read-Host "Is [$logonname] correct  or would you like to change it (Y/C)"
  if ($confirm -ne "y" -or $confirm -ne "Y"){
       #proceed

     } else {
     }
     if($confirm -eq "y" -or $confirm -eq "Y"){
     }else { $logonname = Read-Host "Enter custom logon name"
     }

   Write-Host
   $confirm = Read-Host "Please confirm [$logonname] is correct (Y or N)"
   if ($confirm -ne "y" -or $confirm -ne "Y"){
     #proceed
   }
     } 
        until ($confirm -eq "y" -or $confirm -eq "Y")     

        Write-Host $logonname
