How to Create an Operating System Deployment Task Sequence Group
Updated: November 1, 2013
Applies To: System Center 2012 Configuration Manager, System Center 2012 Configuration Manager SP1, System Center 2012 R2 Configuration Manager
An operating system deployment task sequence group, in System Center 2012 R2 Configuration Manager, can be added to a task sequence by creating an instance of the SMS_TaskSequence_Group class. The group is then added to the list of steps of the task sequence. The list of steps is an array of the SMS_TaskSequence_Step derived classes. The array is stored in the task sequence, SMS_TaskSequence, Steps property.
To create a task sequence group
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.
Create an instance of the SMS_TaskSequence_Group class.
Populate the group with the appropriate properties.
Update the task sequence Steps property with the new group.
Example
The following example method adds a new group to the supplied task sequence. Because the group is added to the end of the task sequence Steps array, you might want to reorder its position. For more information, see How to Reorder an Operating System Deployment Task Sequence.
For information about calling the sample code, see Calling Configuration Manager Code Snippets.
Sub AddTaskSequenceGroup(connection, taskSequence, name, description)
Dim group
' Create and populate the group.
Set group = connection.Get("SMS_TaskSequence_Group").SpawnInstance_
group.Name=name
group.Description=description
group.Enabled=True
group.ContinueOnError=False
' Resize the task sequence steps array to hold the new group.
ReDim steps (UBound (taskSequence.Steps)+1)
' Add the group.
taskSequence.Steps(UBound(steps))=group
End Sub
public IResultObject AddTaskSequenceGroup( WqlConnectionManager connection, IResultObject taskSequence, string name, string description) { try { // Create the new group. IResultObject ro = connection.CreateEmbeddedObjectInstance("SMS_TaskSequence_Group"); ro["Name"].StringValue = name; ro["Description"].StringValue = description; ro["Enabled"].BooleanValue = true; ro["ContinueOnError"].BooleanValue = false; // Add the group to the task sequence. List<IResultObject> array = taskSequence.GetArrayItems("Steps"); array.Add(ro); // Add the new group to the end of the current steps. taskSequence.SetArrayItems("Steps", array); return ro; } catch (SmsException e) { Console.WriteLine("Failed to create Task Sequence: " + e.Message); throw; } }
