Foreach Item do Foreach?

PowerShell Help

Hi,

I have a foreach loop on a variable that also contains and array of data. Whats the best way to loop through the first set of data and then foreach item in the next set to do somethings.

so kinda like

foreach ($Item in $Data){
 if ($Item.Value -eq "Names"){
 foreach($name in $Item.Value.Names){
    Do-Something .....
    }
  }
}

Hope this makes sense?

Cheers

Tommy

That’s exactly how.

Cool, thanks Don. Following on from this. If i wanted the script to execute different commands based on the value $Item.Value. What would be the best way.

I suppose i could use loads of Try statements, maybe something like this…

foreach ($Item in $Data){
    try {
    if ($Item.Value -eq "Names"){
    foreach($name in $Item.Value.Names){
       Do-Something .....
       }
     }
   }
   Catch{
            Do-Something
        } 
    try {
        if ($Item.Value -eq "Something"){
            foreach($Something in $Item.Value.Something){
               Do-Something .....

        }
    }
}
    catch {
            Do-Something
         }
    elseif {
            Do-Something
    }
}

Is there a better way?

I’m not following what the Try blocks are meant for…? Just If constructs, or Switch if you’ve a bunch of different values to test against.

Oh Okay. So running multiple “If” constructs is acceptable in a single Try/Catch block?
