Programmatically Getting CRM Entiry Picklist Option value

Whenever use picklist in CRM Entity’s Attribute you have to collect all picklist options in any collections like ArrayList, HashTable OR controls like DropDownList, ListBox etc. for display Options in UI.
For collecting Picklist Options you have to use CRM’s MetaDataService.asmx as older Post.
See the below sample code snippet for collect picklist options.

RetrieveAttributeRequest request = new RetrieveAttributeRequest();//Create Obj for RetrieveAttributeRequest

            request.EntityLogicalName = CrmSdk.EntityName.new_crmcustomentity.ToString();//Assign CRM's Custom Entity

            request.LogicalName = "new_customattribute";//Set Obj's Picklist Attribute Name

           

            //Now collect entity's response using Metadataservice execution

            RetrieveAttributeResponse response = (RetrieveAttributeResponse)service.Execute(request);//service is MetaDataService.asmx's object

            //collect Picklist Attribute Metadata value

            PicklistAttributeMetadata picklist = (PicklistAttributeMetadata)response.AttributeMetadata;



            //here I use DropDownList for collecting PickList Options

            foreach (Option o in picklist.Options)

            {

                objDropDownList.Items.Add(new ListItem(o.Label.UserLocLabel.Label, o.Value.Value.ToString()));

            }
