.SYNOPSIS
A wrapper around Write-Host that supports selective coloring of
substrings via embedded coloring specifications.
.DESCRIPTION
In addition to accepting a default foreground and background color,
you can embed one or more color specifications in the string to write,
using the following syntax:
#<fgcolor>[:<bgcolor>]#<text>#
<fgcolor> and <bgcolor> must be valid [ConsoleColor] values, such as 'green' or 'white' (case does not matter).
Everything following the color specification up to the next '#', or impliclitly to the end of the string,
is written in that color.
Note that nesting of color specifications is not supported.
As a corollary, any token that immediately follows a color specification is treated
as text to write, even if it happens to be a technically valid color spec too.
This allows you to use, e.g., 'The next word is #green#green#.', without fear
of having the second '#green' be interpreted as a color specification as well.
.PARAMETER ForegroundColor
Specifies the default text color for all text portions
for which no embedded foreground color is specified.
.PARAMETER BackgroundColor
Specifies the default background color for all text portions
for which no embedded background color is specified.
.PARAMETER NoNewline
Output the specified string withpout a trailing newline.
.NOTES
While this function is convenient, it will be slow with many embedded colors, because,
behind the scenes, Write-Host must be called for every colored span.
.EXAMPLE
Write-HostColored "#green#Green foreground.# Default colors. #blue:white#Blue on white."
.EXAMPLE
'#black#Black on white (by default).#Blue# Blue on white.' | Write-HostColored -BackgroundColor White

'StringBuilder' 객체 색상의 어떤 개념이 없습니다. 색상을 원한다면 문자열 내에 이스케이프 코드를 삽입하고 문자열을 원하는 색상으로 출력해야합니다. –
@ Bill_Stewart 당신은 작은 것을 어떻게 사용합니까? 문자열에 색상을 인쇄하는 몇 가지 기능을 찾았습니다. https://stackoverflow.com/questions/2688547/multiple-foreground-colors-in-powershell-in-one-command하지만 일부 기본 코드가있을 수 있습니다. "{color : # 8B0000}"이것은 빨간색 선입니다. – E235
직접 작성해야합니다. 코드의 표시 부분에서는 포함 된 채색을 찾고 그대로 출력해야합니다. 이 작업을 수행 할 기본 제공 항목이 없습니다. 색상은 "출력 전용"기능입니다. –
