PowerShell 区分大小写变量 [英] PowerShell case sensitivity variables

问题描述

我想编写一个脚本来对我公司的用户进行操作.

I want to write a script that does a manipulation on users in my company.

用户名可以是大写/小写字母，有时域名也可以用大写字母分配给他们，所以用户名可以是这样的:域\用户名、域\用户名、域\用户名或域\用户名.

Usernames can be with capital letters/small letters, and also the domain name is sometimes assigned to them with capital letters, so a username can be like: domain\username, DOMAIN\USERNAME, DOMAIN\username or domain\USERNAME.

我这样要求用户名:

$user = Read-Host "Please insert username"

如何使 $user 不区分大小写以及公司名称?

How can I make $user non case sensitive and also the company name?

用户名需要像 $company\$user 一样，不区分大小写.

The username needs to be like $company\$user without case sensitivity.

推荐答案

默认情况下，PowerShell 中的字符串比较通常不区分大小写.

String comparisons in PowerShell are typically case-insensitive by default.

字符串本身感知，这意味着它们知道A与a是不同的字形，并且它会记住使用的是哪个，但是普通的比较运算符(-eq、-match、-like、-lt、-in 等)都是不区分大小写的.

Strings themselves are case aware, meaning they know that an A is a different glyph than an a and it will remember which was used, but the normal comparison operators (-eq, -match, -like, -lt, -in, etc.) are all case-insensitive.

您必须为区分大小写的比较指定区分大小写的版本(-ceq、-cmatch、-clike、-clt、-cin 等).您还可以指定显式不区分大小写的运算符(-ieq、-imatch、-ilike、-ilt、-iin 等).

You have to specify the case-sensitive versions for case-sensitive comparisons (-ceq, -cmatch, -clike, -clt, -cin, etc.). You can also specify the explicitly case-insensitive operators (-ieq, -imatch, -ilike, -ilt, -iin, etc.).

如果要强制字符为特定大小写，可以这样做:

If you want to force the characters to a specific case, you can do this:

#Set characters to lower case
$user = $user.ToLower();

#Set characters to upper case
$user = $user.ToUpper();

但是没有字符串的属性将它们标记为天生不区分大小写.

But there is no property of strings that marks them as inherently case-insensitive.
