$text = "thIS is A TEST teXT" [CultureInfo]::InvariantCulture.TextInfo.ToTitleCase($text) Words that are ALL CAPITALIZED will remain untouched:
This Is A TEST Text
如果您不喜欢有些例外的单词没有被转成首字母大写，那么先将文本转为全小写然后传给该方法：
1 2 3 4 5
PS> [CultureInfo]::InvariantCulture.TextInfo.ToTitleCase('TEST remains aLL uppER Case') TEST Remains All Upper Case
PS> [CultureInfo]::InvariantCulture.TextInfo.ToTitleCase('TEST remains aLL uppER Case unless you lowerCASE YOUR text beFORE'.ToLower()) Test Remains All Upper Case Unless You Lowercase Your Text Before
$text = "thIS is A TEST teXT" # title convert and then replace two or more spaces with one space only: [CultureInfo]::InvariantCulture.TextInfo.ToTitleCase($text.ToLower()) -replace'\s{2,}', ' ' Now this approach returns the exact same result as in our previous parts:
process { [CultureInfo]::InvariantCulture.TextInfo.ToTitleCase($text.ToLower()) -replace'\s{2,}', ' ' } }
当您运行该函数，它将和之前的版本一样灵活和可扩展：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

By assigning the enum type [ServerTypes] to your result variable, all translating is performed automatically, and cryptic code numbers now show as friendly text. 通过将枚举类型 [ServerTypes] 绑定到您的结果变量，所有转换都会自动进行，而且现在幻数可以转换为友好的文本。
