Retrieve Option Set Metadata in C#

Views (20123)

Given the name of an entity and the name of an option set field, Microsoft.Xrm.Sdk.Messages can retrieve all the labels and corresponding integer values for an option set.

Simply build a new RetrieveAttributeRequest and iterate over the response like so:

var attributeRequest = new RetrieveAttributeRequest
{
    EntityLogicalName = "entityName",
    LogicalName = "attributeName",
    RetrieveAsIfPublished = true
};

var attributeResponse = (RetrieveAttributeResponse)service.Execute(attributeRequest);
var attributeMetadata = (EnumAttributeMetadata)attributeResponse.AttributeMetadata;

var optionList = (from o in attributeMetadata.OptionSet.Options
                  select new { Value = o.Value, Text = o.Label.UserLocalizedLabel.Label }).ToList();

optionList now contains a list of all option set options where each object in the list has a Value property and a Text property.

To retrieve a given option set value for a label, use a Linq query:

var activeValue = optionList.Where(o => o.Text == "Active")
                                        .Select(o => o.Value)
                                        .FirstOrDefault();
