When judging conditions, $True and $False are indispensable. When converting other types into Bool types, there are several points to pay attention to:
Convert other types to boolean types
PS> 0,1,-1,'0','1','true','false',$null | foreach { [bool]$_ }
False
True
True
True
True
True
True
False
Summary: Only integers 0 and Null can be converted to False, and others will be cast to True
Boolean type converted to string
Copy the codeThe code is as follows:
PS> $true,$false | foreach { $_.ToString() } True False
There should be no suspense about this.
Boolean type converted to integer
Copy the codeThe code is as follows:
PS> $true,$false | foreach { [int] $_ } 1 0
It is also understandable that 1 and 0 represent true and false, respectively.
