Publicado: novembro de 2016
Aplicável a: Dynamics CRM 2015
Este código de exemplo é para o Atualização do Microsoft Dynamics CRM 2015 e Microsoft Dynamics CRM Online 2015. Baixe o pacote do SDK do Microsoft Dynamics CRM. Pode ser encontrado no seguinte local no pacote de download:

Demonstra
Este exemplo mostra como determinar se um usuário no Microsoft Dynamics 365 foi associado a uma função específica. Isso é executado usando uma consulta com o método IOrganizationService.RetrieveMultiple. Um trecho que mostra as principais seções do exemplo é mostrada primeiro, seguido pelo Código de Exemplo Completo. Observe que esse exemplo pode ser executado apenas em um ambiente local porque cria um usuário. Entretanto, a parte do exemplo que demonstra a recuperação das funções para um usuário funciona em todos os ambientes.

// Connect to the Organization service.
// The using statement assures that the service proxy will be properly disposed.
using (_serviceProxy = new OrganizationServiceProxy(serverConfig.OrganizationUri, serverConfig.HomeRealmUri,serverConfig.Credentials, serverConfig.DeviceCredentials))

_serviceProxy.EnableProxyTypes();
CreateRequiredRecords();
// Retrieve a user.
SystemUser user = _serviceProxy.Retrieve(SystemUser.EntityLogicalName,
_userId, new ColumnSet(new String [] {"systemuserid", "firstname", "lastname"})).ToEntity<SystemUser>();
if (user != null)
{
Console.WriteLine("{1} {0} user account is retrieved.", user.LastName, user.FirstName);
// Find a role.
