Hash table containskey does not work

[JoergenKaare]

The following code does not find key in hashtable:

# Wait while there are less than $maxTask running

      while($taskTab.Count -ge $maxTasks){

          out-log "Max tasks running" "yellow"

          sleep 15

          Get-Task| where {$_.name -eq "RelocateVM_Task"} | %{

                write-host "ID " $_.id

                $tasktab.Keys | % { "key = $_ , value = " + $tasktab.Item($_) }

               if($taskTab.ContainsKey($_.id) ){

                    Write-host "Task found"

                    if ($_.State -eq "Success") {

                    $taskTab.Remove($_.Id)

                    write-host "remove task"

                    }

               }

          }

     } #end while

Doing some tests:

display keys from table:

PS C:\WINDOWS\system32> $tasktab.Keys | % { "key = $_ , value = " + $tasktab.Item($_) }

key = Task-task-4059866 , value = T-JKJ-test06

Test if key exist fails

PS C:\WINDOWS\system32> if ($tasktab.containskey("Task-task-4059866") ){write-host "found"} else {write-host "not found"}

not found

Any suggestions?

Hard to tell if you don't show how you built the content of $taskTab.

Sorry, forgot that – here it is

$disks=$vm|Get-harddisk|% {$_.id.split('/')[1]}  #-> 3 disk ids should be here

    $spec = New-Object VMware.Vim.VirtualMachineRelocateSpec

    $spec.Host = $esx.extensiondata.moref

    $spec.pool = $TCluster.extensiondata.resourcepool

    $spec.datastore = New-Object VMware.Vim.ManagedObjectReference

    $spec.datastore.type = "Datastore"

$spec.datastore.Value = $dsos

    $spec.disk = New-Object VMware.Vim.VirtualMachineRelocateSpecDiskLocator[] (3)

    $spec.disk[0] = New-Object VMware.Vim.VirtualMachineRelocateSpecDiskLocator

    $spec.disk[0].diskId = $disks[0]

    $spec.disk[0].datastore = New-Object VMware.Vim.ManagedObjectReference

    $spec.disk[0].datastore.type = "Datastore"

$spec.disk[0].datastore.Value =  $dsOS

    $spec.disk[1] = New-Object VMware.Vim.VirtualMachineRelocateSpecDiskLocator

    $spec.disk[1].diskId = $disks[1]

    $spec.disk[1].datastore = New-Object VMware.Vim.ManagedObjectReference

    $spec.disk[1].datastore.type = "Datastore"

$spec.disk[1].datastore.Value =  $dsPF

    $spec.disk[2] = New-Object VMware.Vim.VirtualMachineRelocateSpecDiskLocator

    $spec.disk[2].diskId = $disks[2]

    $spec.disk[2].datastore = New-Object VMware.Vim.ManagedObjectReference

    $spec.disk[2].datastore.type = "Datastore"

$spec.disk[2].datastore.Value = $dsData

    $tasktab[((Get-View -Id $vm.id).RelocateVM_Task($spec, "defaultPriority"))] =$vmname

There are a few issues with your code.

- You can't use the the [] notation on a hash table if that key does not exists yet.

The correct way would be to use the Add method.

- The Task object is an object with 2 properties, Type and Value.

When you compare this with a string, you are relying on implicit type conversion, which will not work in this case.

Better is to explicitly cast the desired type.

When you do

$tasktab.Add((Get-View -Id $vm.id).RelocateVM_Task($spec, "defaultPriority").ToString(),$vmname)

you will be able to do a ContainsKey with a [string] value

$tasktab.ContainsKey('Task-task-12345')

Thanks Luc, i works:-)
