Retrieve Option Set Metadata in C#

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();
