==============

I wrote some method to get picklist value by knowing picklist name.

namespace test
{
public class CrmServiceProvider
{

private WebMetadataService.MetadataService _MetaService = null;

///* Create a MetadataService end point */
private WebMetadataService.MetadataService MetaService
{
get
{
if (_MetaService == null)
{
_MetaService = new WebMetadataService.MetadataService();
_MetaService.Url = "http://localhost/mscrmservices/2007/metadataservice.asmx";

// Use a special user credentials
NetworkCredential cred = new NetworkCredential();
cred.Domain = ConfigurationManager.AppSettings["Domain"];
cred.UserName = ConfigurationManager.AppSettings["UserName"];
cred.Password = ConfigurationManager.AppSettings["PassWord"];

_MetaService.UseDefaultCredentials = false;
_MetaService.Credentials = cred;

_MetaService.UnsafeAuthenticatedConnectionSharing = true;

WebMetadataService.CrmAuthenticationToken token = new WebMetadataService.CrmAuthenticationToken();
token.AuthenticationType = 0;
token.OrganizationName = ConfigurationManager.AppSettings["Organization"];

_MetaService.CrmAuthenticationTokenValue = token;
}
return _MetaService;
}
}


public int GetPicklistValueByPicklistName(string PicklistName, string EntityLogicalName, string LogicalName)
{
int retval = -1;

/* Retrieve the attribute metadata */
WebMetadataService.RetrieveAttributeRequest attributeRequest = new WebMetadataService.RetrieveAttributeRequest();
attributeRequest.EntityLogicalName = EntityLogicalName;
attributeRequest.LogicalName = LogicalName; //picklist

WebMetadataService.RetrieveAttributeResponse attributeResponse =
(WebMetadataService.RetrieveAttributeResponse)MetaService.Execute(attributeRequest);

/* Cast the attribute metadata to a picklist metadata */
WebMetadataService.PicklistAttributeMetadata picklist =
(WebMetadataService.PicklistAttributeMetadata)attributeResponse.AttributeMetadata;


foreach (WebMetadataService.Option op in picklist.Options)
{
if (op.Label.UserLocLabel.Label == PicklistName)
retval = op.Value.Value;
}

return retval;
}
}
}

To call this method use then next construction:
int psv = GetPicklistValueByPaymentSystemName(categorycode, "account", "accountcategorycode");
if (psv > 0)
{
acc.accountcategorycode = new Picklist();
acc.accountcategorycode.Value = psv;
}

Неплохой пример работы с метаданными.
