Question

I have 2 pieces of code:

# code 1:
[type]$t1 = [switch] 
# all is ok, code works as expected

#code 2:
function test ([type]$t2) {  }
test -t2 [switch]
# here we get error. can't convert from string to system.type

I know, I can write: test -t2 "System.Management.Automation.SwitchParameter", but it’s ugly!!
Why can i set [switch] to [type]variable, but can’t pass it to function??

Answer 1

You can do this:

test -t2 "switch"

Or you can use the example from code1 and pass in the $t1 itself:

function test ([type]$t2) {  }
[type]$t1 = [switch] 
test -t2 $t1
