Este ejemplo muestra cómo determinar si se ha asociado a un usuario de Microsoft Dynamics 365 con un rol específico. Para llevar a cabo esta acción se utiliza una consulta con el método IOrganizationService.RetrieveMultiple. Un fragmento de código que muestra las secciones principales de ejemplo se muestra en primer lugar, seguido por el Código de ejemplo completado. Tenga en cuenta que este ejemplo solo se puede ejecutar a un entorno local porque crea un usuario. Sin embargo, la sección del ejemplo que demuestra cómo recuperar los roles de un usuario funcionará para todos los entornos.
Ejemplo
// 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.
QueryExpression query = new QueryExpression
{
EntityName = Role.EntityLogicalName,
ColumnSet = new ColumnSet("roleid"),
Criteria = new FilterExpression
{
Conditions =

// Get the role.
