OK, so – you've figured out how to create enumerations (in bulk even ), use them in custom forms using the special ListPicker control , how to set enum property values , and how to add them to a form using form customization .  In this blog post, I'll show you how to manipulate enumerations programmatically using the SDK. Using this information you can create custom web forms, command line apps, PowerShell cmdlets, or Windows Workflow Foundation activities that need to manipulate enum data type properties.

Here are a few examples:

EnterpriseManagementGroup emg = new EnterpriseManagementGroup("localhost");

//Get all enumerations and list them in a list

foreach(ManagementPackEnumeration mpenum in emg.EntityTypes.GetEnumerations())




//Get a specific enumeration by GUID

ManagementPackEnumeration mpenumIncidentUrgencyHigh = emg.EntityTypes.GetEnumeration(new Guid("2F8F0747-B6CB-7996-FD4A-84D09743F218"));


//Get a specific enumeration by Name and MP

ManagementPack mpSystem = emg.ManagementPacks.GetManagementPack(SystemManagementPack.System);

Version verSystemVersion = mpSystem.Version;

string strSystemKeyToken = mpSystem.KeyToken;

ManagementPack mpWorkItemLibrary = emg.GetManagementPack("System.WorkItem.Library", strSystemKeyToken, verSystemVersion);

mpenumIncidentUrgencyHigh = emg.EntityTypes.GetEnumeration("System.WorkItem.TroubleTicket.UrgencyEnum.High",mpWorkItemLibrary);


//Get a parent enumeration and enumerate all of its children

ManagementPackEnumerationCriteria mpenumcriteriaChildrenOfIncidentUrgencyParent = new ManagementPackEnumerationCriteria("Parent = '04B28BFB-8898-9AF3-009B-979E58837852'");

IList<ManagementPackEnumeration> listenumIncidentUrgency = emg.EntityTypes.GetEnumerations(mpenumcriteriaChildrenOfIncidentUrgencyParent);

foreach (ManagementPackEnumeration mpenumIncidentUrgency in listenumIncidentUrgency)
