サンプル: ユーザーにロールがあるかどうかを判断する
公開日: 2017年1月
対象: Dynamics 365 (online)、Dynamics 365 (on-premises)、Dynamics CRM 2016、Dynamics CRM Online
このサンプル コードは、Microsoft Dynamics 365 (オンラインおよび設置型) 向けです。Microsoft Dynamics CRM SDK パッケージをダウンロードします。 これは、ダウンロード パッケージの次の場所にあります。
SampleCode\CS\BusinessDataModel\UsersAndRoles\DoesUserBelongToRole.cs
要件
この SDK で提供するサンプル コードを実行するために必要な要件については、「サンプルとヘルパー コードの使用」を参照してください。
使用例
このサンプルは、Microsoft Dynamics 365のユーザーが特定のロールに関連付けられているかどうかを確認する方法を示します。 これはIOrganizationService.RetrieveMultiple 方法とクエリを使用して実行されます。 最初に、サンプルのキー セクションを示すスニペット、次に サンプル コードの完了を示します。 ユーザーを作成するため、このサンプルは設置型環境でのみ実行可能なことに注意してください。 ただし、ユーザーのロールを取得したことを示すサンプルの一部は、すべての環境で機能します。

// 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.
