The PowerShell -and conditional operator

Question

Either I do not understand the documentation on MSDN or the documentation is incorrect   if  user sam -ne    -and  user case -ne           Write-Host  Waaay  Both vars have values     else       Write-Host  One or both of the vars are empty       I hope you understand what I am attempting to output  I want to populate  user sam and  user case in order to access the first statement

Another option   if    string   IsNullOrEmpty  user sam  -and   string   IsNullOrEmpty  user case

User · Answer

Try like this   if  user sam -ne  NULL -and  user case -ne  NULL    Empty variables are  null and then different from      string   empty

You can simplify it to  if   user sam -and  user case              because empty strings coerce to  false  and so does  null  for that matter

The code that you have shown will do what you want iff those properties equal    when they are not filled in  If they equal  null when not filled in for example  then they will not equal     Here is an example to prove the point that what you have will work for       foo   1  bar   1  foo -eq 1 -and  bar -eq 1 True  foo -eq 1 -and  bar -eq 2 False
