You enumerate an operating system deployment task sequence, in System Center 2012 Configuration Manager, by using a recursive method to scan through the task sequence steps and groups.
To enumerate the steps in a task sequence
-
Set up a connection to the SMS Provider. For more information, see About the SMS Provider in Configuration Manager.
-
Obtain a valid task sequence SMS_TaskSequence object. For more information, see How to Create an Operating System Deployment Task Sequence
-
Enumerate through the steps to display any action (SMS_TaskSequence_Actions names. Use recursion to access any groups (SMS_TaskSequence_Group) that are found and display their actions.
Example
The following example displays the actions and groups within a task sequence.
For information about calling the sample code, see Calling Configuration Manager Code Snippets.
Visual Basic Script | Copy Code |
---|---|
Sub RecurseTaskSequenceSteps(taskSequence, indent) Dim osdStep Dim i ' Indent each new group. for each osdStep in taskSequence.Steps for i=0 to indent WScript.StdOut.Write " " next If osdStep.SystemProperties_("__CLASS")="SMS_TaskSequence_Group" Then wscript.StdOut.Write "Group: " End If WScript.Echo osdStep.Name ' Recurse into each group found. If osdStep.SystemProperties_("__CLASS")="SMS_TaskSequence_Group" Then If IsNull(osdStep.Steps) Then Wscript.Echo "No steps" Else Call RecurseTaskSequenceSteps (osdStep, indent+3) End If End If Next End Sub |
C# | Copy Code |
---|---|
public void RecurseTaskSequenceSteps( IResultObject taskSequence, int indent) { try { // The array of SMS_TaskSequence_Steps. List<IResultObject> steps = taskSequence.GetArrayItems("Steps"); foreach (IResultObject ro in steps) { for (int i = 0; i < indent; i++) { Console.Write(" "); } if (ro["__CLASS"].StringValue == "SMS_TaskSequence_Group") { Console.Write("Group: "); } Console.WriteLine(ro["Name"].StringValue); // Child groups that are found. Use recursion to view them. if (ro["__CLASS"].StringValue == "SMS_TaskSequence_Group") { this.RecurseTaskSequenceSteps(ro, indent + 3); } } } catch (SmsException e) { Console.WriteLine("Failed To enumerate task sequence items: " + e.Message); throw; } } |
The example method has the following parameters:
Parameter | Type | Description |
---|---|---|
taskSequence |
|
A valid task sequence (SMS_TaskSequence). The group is added to this task sequence. |
indent |
|
Indent is used to space console output for child groups. |
