Cool!

So why does this fail:

PSH [D:\foo]: $e="[enum]::GetNames([system.consolecolor])"
PSH [D:\foo]: $e
[enum]::GetNames([system.consolecolor])
PSH [D:\foo]: & $e
The term '[enum]::GetNames([system.consolecolor])' is not recognized as
a cmdlet, function, operable program, or script file. Ver
ify the term and try again.
At line:1 char:2
+ & <<<< $e

Whereas this works fine when typed from the commend line

PSH [D:\foo]: [enum]::GetNames([system.consolecolor])
Black
DarkBlue
DarkGreen
DarkCyan
DarkRed
DarkMagenta
DarkYellow
Gray
DarkGray
Blue
Green
Cyan
Red
Magenta
Yellow
White
PSH [D:\foo]:

With a string, you want to use Invoke-Expression e.g.:

2> $e="[enum]::GetNames([system.consolecolor])"
3> Invoke-Expression $e
Black
DarkBlue
DarkGreen
DarkCyan
DarkRed
DarkMagenta
DarkYellow
Gray
DarkGray
Blue
Green
Cyan
Red
Magenta
Yellow
White

If you want to call the code later then put it in a scriptblock.

4> $e={[enum]::GetNames([system.consolecolor])}
5> &$e
Black
DarkBlue
DarkGreen
DarkCyan
DarkRed
DarkMagenta
DarkYellow
Gray
DarkGray
Blue
Green
Cyan
Red
Magenta
Yellow
White
