Question

I have this array:

$Cluster = @( ("vcdvc012", "CL-CC5-DR"),
    ("vcdvc013", "CL-CCL3-DR"))

Now I would like to search for "vcdvc012" to be able to get as result "CL-CC5-DR".

What is the best way to do this? Gabrie

Answer 1

尝试：

$Cluster | ? { $_[0] -eq 'vcdvc012' } | % { $_[1] }

Answer 2

Frode has a general answer but it relies on knowing the location of the element. Since you are dealing with arrays the operators -contains and -in would be beneficial here. Won't change much for the selection of the second element unless you created your own custom objects.

$Cluster | Where-Object {$_ -contains 'vcdvc012'} | ForEach-Object{ $_[1] }
$Cluster | Where-Object {'vcdvc012' -in $_} | ForEach-Object{ $_[1] }

Both would work just the same. The latter is more intuitive as many confused the functionality of -contains . -in was made available in v3.0
