How to get the option set from a field in an entity in CRM 2011 using crm sdk and C#? I just want to share with you guys a direct approach on getting the option set of a fie

Answer 1

depends if it's local or global. If it is local then:

string optionsetText = entity.FormattedValues["new_optionset"];

if its global then you need a lot more code:

        public static string GetoptionsetText(string entityName, string attributeName, int optionSetValue, IOrganizationService service)
    {
        string AttributeName = attributeName;
        string EntityLogicalName = entityName;
        RetrieveEntityRequest retrieveDetails = new RetrieveEntityRequest
        {
            EntityFilters = EntityFilters.All,
            LogicalName = EntityLogicalName
        };
        RetrieveEntityResponse retrieveEntityResponseObj = (RetrieveEntityResponse)service.Execute(retrieveDetails);
        Microsoft.Xrm.Sdk.Metadata.EntityMetadata metadata = retrieveEntityResponseObj.EntityMetadata;
        Microsoft.Xrm.Sdk.Metadata.PicklistAttributeMetadata picklistMetadata = metadata.Attributes.FirstOrDefault(attribute => String.Equals(attribute.LogicalName, attributeName, StringComparison.OrdinalIgnoreCase)) as Microsoft.Xrm.Sdk.Metadata.PicklistAttributeMetadata;
        Microsoft.Xrm.Sdk.Metadata.OptionSetMetadata options = picklistMetadata.OptionSet;
        IList OptionsList = (from o in options.Options
                                             where o.Value.Value == optionSetValue
                                             select o).ToList();
        string optionsetLabel = (OptionsList.First()).Label.UserLocalizedLabel.Label;
        return optionsetLabel;

I got that from Guido on another similar question but rcados is missing the 3rd parameter. To get the text you just set

var foo = GetoptionsetText("lead", "picklist", 1234 , service)

assuming you have already declared IorganizationService
