PowerShell实现在字符串中查找大写字母

$text = 'here is some text with Uppercase letters' $c = 0$position = foreach ($character in $text.ToCharArray()){ $c++ if ([Char]::IsUpper($character)) {  $c  break }} if ($position -eq $null){ 'No uppercase characters detected.'}else{ "First uppercase character at position $position" $text.Substring(0, $position) + "<<<" + $text.Substring($position)}

PS C:/>First uppercase character at position 24 here is some text with U<<
