    I am trying to iterate through a SPWorkflowTaskCollection but get the error below..

    ... Is there another technique?

    Method invocation failed because [Microsoft.SharePoint.Workflow.SPWorkflo

    wTaskCollection] doesn't contain a method named 'GetEnumerator'.

    At C:\Users\nyannios\Documents\OLF-ModClientsWorkflows.ps1:813 char:39

    + $IEnum = $tasks.GetEnumerator <<<<

    ()

    + CategoryInfo : InvalidOperation: (GetEnumerator:String) [

    ], RuntimeException

    + FullyQualifiedErrorId : MethodNotFound

     

    $tasks = [Microsoft.SharePoint.Workflow.SPWorkflowTaskCollection]
$task = [Microsoft.SharePoint.Workflow.SPWorkflowTask]
$IEnum = [System.Collections.IEnumerable]
.
.
.
$tasks = $_.Tasks
$IEnum = $tasks.GetEnumerator()
while ($IEnum.MoveNext())
{
  $task = $IEnum.Current
   write-Host "Task: " $task.DisplayName 
.
.
.
}

    more detail: 
$ClientWebs | 
%{ 
	$WebI = $_
	Write-Host; "Web: " + $_.Title; $l = $_.Lists; $l | 
	%{ 
		$specificList = $_
		$wfAssocArray = $_.WorkflowAssociations
		write-host "List: " $_.Title ; $_.WorkflowAssociations |%{ 
		$wfassoc = $_
		$wfid = $_.Id 
		' Workflow Association Name: {0} Internal: {1}' -f $_.Name, $_.InternalName
		$specificList.Items | 
		%{ 
			$spitem = $_
			$_.Workflows | 	%{ 
				$wfCount += 1
				Write-Host -ForegroundColor Blue "WF: " $_.InstanceId $_.InternalState $_.IsCompleted $_.IsLocked
				if ($_.InternalState -match "Completed") {$wfCompleted += 1} 
				if ($_.InternalState -match "Running") {$wfRunning += 1}
				$tasks = $_.Tasks
				$IEnum = $tasks.GetEnumerator()
				while ($IEnum.MoveNext())
				{
					$task = $IEnum.Current
					write-Host -ForegroundColor DarkMagenta "Task: " $task.DisplayName 
				}
			}

 				{
 					write-Host -ForegroundColor DarkMagenta "Task: " $task.DisplayName 
                                             .
                                             .
                                             .

 				}
 			}
 		}
		}
	}
}

    changed from using GetEnumerator() to simply using foreach() to iterate through the tasks.  That worked.  Now i can edit through all the associated tasks with a workflow instance and find their associated Task Lists, etc.
