Weitere Informationen zu den Anforderungen zum Ausführen des in diesem SDK enthaltenen Beispielcodes finden Sie unter Verwenden des Beispiel- und Hilfscode.
Demonstriert
Dieses Beispiel zeigt, wie Sie eine Rolle eines Benutzers mithilfe der IOrganizationServiceDisassociate-Methode entfernen. Ein Ausschnitt, der nur die Schlüsselabschnitte des Beispiels enthält, wird zuerst angezeigt, gefolgt vom Vollständiger Beispielcode. Beachten Sie, dass dieses Beispiel nur ein einer lokalen Umgebung ausgeführt werden kann, da sie einen Benutzer erstellt. Allerdings funktioniert der Abschnitt mit dem Beispiel, der zeigt, wie die Rolle eines Benutzers entfernt wird, in jeder Umgebung.
Beispiel
// Connect to the Organization service.
// The using statement assures that the service proxy is 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.FirstName, user.LastName);
// Find the role.
QueryExpression query = new QueryExpression
{
EntityName = "role",
ColumnSet = new ColumnSet("roleid"),
Criteria = new FilterExpression
{
Conditions =
{
new ConditionExpression
{
AttributeName = "name",
Operator = ConditionOperator.Equal,
Values = {_givenRole}
}
}
}
};
// Get the role.
EntityCollection roles = _serviceProxy.RetrieveMultiple(query);
// Disassociate the role.
if (roles.Entities.Count > 0)
{
Role salesRole = _serviceProxy.RetrieveMultiple(query).Entities[0].ToEntity<Role>();
Console.WriteLine("Role {0} is retrieved.", _givenRole);
_serviceProxy.Disassociate(
"systemuser",
user.Id,

new EntityReferenceCollection() { new EntityReference("role", salesRole.Id) });
Console.WriteLine("Role {0} is disassociated from user {1} {2}.", _givenRole, user.FirstName, user.LastName);
